Casey Cornaire fall2013 Opus
Its a Dick for!
Last semester! JOE FREEEEEEE!!!!!!
8-28-13
in class today we discussed reviewed memory and data types in class. we also reviewed how to allocate memory. we went over the opus and then discussed the first project for the class which is to either do free cell, forty thieves or eight off.

today we built a program that dealt with arrays, structs, and loops as a review
#include <stdio.h>
#include <stdlib.h>
int main()
{
struct person{
char *name;
int age;
long int id;
};
typedef struct person Person;
Person People[8];
int i=0;
for(i=0; i<8; i++)
{
fprintf(stdout, "Enter person #%d's name: ", (i+1));
People[i].name=(char*)malloc(sizeof(char)*20);
fscanf(stdin, "%s", People[i].name);
fprintf(stdout, "Enter %'s age: ", People[i].name);
fscanf(stdin, "%d", &People[i].age);
fprintf(stdout, "Enter %s's id number: ", People[i].name);
fscanf(stdin, "%ld", &People[i].id);
}
i=-1;

fscanf(stdin, "%d", &i);
if(!((i>=0)&&(i<=7)))
{
fprintf(stdout, "Invalid person #, Try Again!\n");

}
}

64 }
today we worked on insert function, we had noticed that if you insert before node 0, it actually puts it after, the following code prevents
if(input==0)
{
fprintf(stdout, "Enter value for new node: "):
fscanf(stdin, "%d", &input);
tmp2=(Node*malloc(sizeof(Node));
tmp2->value=input;
tmp2->next=NULL;
tmp2->next=tmp;
list=tmp2;
}
today we worked on developing a singly liked list, building a list of nodes and manipulating the list with insert, apeend and remove

today we accomplished completing the insert function
List *insert(List *myList, Node *place, Node *newNode)
{
if(place==myList->start)
{
newNode->next=place;
place->prev=newNode;
newNode->prev=NULL;

}
else
{
newNode->next=place;
place->prev->next=newNode;
newNode->prev=place->prev;
place->prev=newNode;
}
return(myList);
}
today we worked on the getNode function or remove
List *getNode(List *myList, Node **place)
{
if(myList->start->next==NULL)
{
myList->start=NULL;
}
else if(*place==myList->start)
{
myList->start=myList->start->next;
myList->start->prev=NULL;
(*place)->next=NULL;
}
else if(*place==myList->end)
{
myList->end=myList->end->prev;
myList->end->next=NULL;
(*place)->prev=NULL;
}
else
{
(*place)->prev->next=(*place)->next;
(*place)->next->prev=(*place)->prev;
(*place)->prev=(*place)->next=NULL;
}
return(myList);
}
today we made a header file for the doubly linked list
#ifndef _DLL_H
#define _DLL_H
#include <stdio.h>
#include <stdlib.h>
struct node {
int value;
struct node *next;
struct node *prev;
};
typedef struct node Node;
struct list {
struct node *start;
struct node *end;
};
typedef struct list List;
List *build();
void displayf(List*);
void displayb(List*);
List *insert(List *, Node *, Node *);
List *append(List *, Node *, Node *);
List *getNode(List *, Node **);
#endif
today I started to work on the menu for the singly linked list will paste code when finished with it all
today we did the knowledge assessment, ouch did that hurt, I need to get a clue!!!
on this day we continued to work on the knowledge assessment, still not good
on this day we took the second part of the knowledge assessment, I really am not good at this stuff
back to the grind, today we talked about stacks,
pop() - takes the item off the stack push() - puts the item on the top of the stack peek() - shows us the top of the stack top - pointer always located at the top of the stack mkstack() - creates new stack
today we worked on creating the push and pop functions
#include "stack.h"
Stack * push(Stack *myStack, Node *newNode)
{
if((*myStack->size <= 0) || (myStack->data->qty < myStack->size))
{
(*myStack)->data = append((*myStack)->data, (*myStack)->data->e$
(*myStack)->top = (*myStack)->data->end;
}
return(myStack);
#include "stack.h"
Node *pop(Stack **myStack)
{
Node *tmp = NULL;
if(myStack != NULL)
{
tmp = getNode(&(*myStack)->data,(*myStack)->data->data->end);
(*myStack)->top = (*myStack)->data->end;
}
return(tmp);
}
today we did a stack test program in class
nclude <stdio.h>
#include "stack.h"
int main()
{
Node *tmp;
Stack *myStack;
myStack = mkstack(0);
tmp = create();
tmp->value = fgetc(stdin);
fgetc(stdin);
while(tmp->value != '\n')
{
myStack = push(myStack, tmp);
tmp = create();
tmp->value = fgetc(stdin);
fgetc(stdin);
}
fprintf(stdout, "linked list has %d nodes\n", myStack->data->qty);
fprintf(stdout, "String is: ");
do {
tmp = pop(&myStack);
if(tmp != NULL)
{
fprintf(stdout, "%c", tmp->value);
}
}
while(tmp != NULL);
fprintf(stdout, "\n");
return(0);
}
today I defeated the clear command for the singly linked list
Node *clear(Node *list) {
Node *tmp = list;
Node *tmp2;
int count;
while(tmp!=NULL)
{
tmp=tmp->next;
count++;
}
tmp=list;
for(; count>0 ; count--)
{
tmp2=tmp->next;
tmp->next=NULL;
free(tmp);
tmp=tmp2;
}
return(NULL);
}
today I worked on the having trouble with the parameters for thmenu for the singly linked list, it is coming along pretty good, but I am trouble with the parameters for the function calls in the case statements
completed my singly link list menu today!!! well minus the sort command though

today I started working on my doubly liked list menu, I wanted to try something a little different with the case statements, will paste code when done.
on this day I worked on my DLL menu and its coming along good, need to start my sort and clear functions soon
on this day I worked on my sort function for my doubly linked list, its a pain in the ass!! but I am slowly getting it done
today I continued on the sort function for the DLL, I keep getting seg faults and I cannot figure out why
continued the sort function today and making some headway, fixed one seg fault but now getting another later down the road, tried the fix for the one before but it didn't work…
today I finished the sort command for my DLL!!
List *sort(List *myList)
{
Node *tmp;
Node *tmp2;
tmp = myList->start;
Node *max;
int back;
int count = 0;
while(tmp != NULL)
{
tmp = tmp->next;
count++;
}
int first = count;
for(; first>1; first--)
{
tmp = myList->start;
tmp2 = myList->start;
max = tmp;
for(; count>0; count--)
{
if(max->value < tmp2->value)
{
max = tmp2;
}
tmp2 = tmp2->next;
}
myList = getNode(myList, &max);
tmp = myList->start;
for(back = 0; back<(first-2); back++)
{
tmp = tmp->next;
}
myList = append(myList, tmp, max);
}
return(myList);
}
Now time to work on the clear function, I was able to get a good portion of it done, will continue tommmorow
continued on the clear function and completed the code just trying to clean up some errors
finished the clear function,
List *clear(List *mylist)
60 {
61 Node *tmp = mylist->start;
62 Node *tmp2;

on this day I made a quantity function and put it in my listops

217
218 }
on this day I worked more on my listops option menu. I have been getting seg faults and was unsure why. apparently it has been the parameters that I have been passing into the insert function. matt helped me with setting it up, upon him leaving, I was getting another segfault that I have not seen before fscanf.c: No such file or directory
I had never seen this before, so I googled the message and found out that it was an ampersand that I was forgetting, but through this I learned about the backtrace and list commands within gdb so that was very helpful!!!
I was getting seg faults for one program bc my build function was not returning anything and was causing my list pointer to be NULL, but that only fixed one.
on this day I made a display file that houses my display function
1 #include "DLL.h"

3 void displayf( List *mylist)
4 {
5 Node *tmp=mylist->start;
6 int input=0;

ON this day I started to get my stack all together and I am getting errors, rtying to work those out
on this day I continued to work on the stack but am getting nowhere, I think im going to start working on my EoCE and implement in C++ and see if I can make it work in there
Worked on my EoCE for C++ inplementation all week!!!!!!!!!!!!!!!!!!!

During this week we set up the raspberry pi's and waited on resistors and LED's
Today I set up the raspberry pi to turn an led on and off, verified by matt
today I did some research on the link set by matt and started the second project
on this day I was able to get the second project completed verified by Matt
on this day I started working on the bit counter, I am starting with a generic version that just lights up the lights in sequence with no bit counter
on this day I continued to work on the generic counter and it is almost finished
on this day I finished my generic counter

On this day I started to work on the counter using arrays, its coming along pretty good but I am having trouble grasping the concept of the counter
on this day I continued the work on my binary counter and it seems to be coming along pretty good, had matt help me with some syntax issues and it got me going in the right direction
on this day I thought I had finished the project and it compiles cleanly but it just wont count correctly, maybe it has something to do with the bit shift but not sure, will resume
I am completely f'n stumped, my code was looked at by a couple people and they agree that it should work, WTF
today we started pn the P2p with connecting 2 pis together and having one be a sender and the other a receiver.
on this day we continued the p2pproject, almost done witht his one
finished the p2p project

1 - 230
on this day I worked on inventorying the lair computer equipment, checking to see if the compters had ram, HD, and whether they worked or not
1 - 230
on this day I continued working on the inventory project
5 to 7
on this day I started to install virtual box and ubuntu so I could have a linux virtual machine on my laptop, took a little while to set up the virtualbox specs
1 to 3
on this day I helped charlotte with arranging equipment in the lair
1 to 230
on this day I continued to assist charlotte with the equipment in the lair
2 - 4
on this day I started to work on inventory in the cage, wow what a mess
1 - 330
On this day I continued the lair cage inventory, slpwly but surely getting it done
1 to 3
on this day I continued in the cage, its very overwhelming but am making some progress
2 - 4
on this day I went back into the cage, I really have no idea what I am going to do with all this stuff…
4 -5
on this day I started to work on my tetris game tutorial.
first lesson: Defines.h
this is where we define all of the aspects of the game like the window, game speed, levels, points, pieces, etc.
on this day I continued with the tutorial, its alot of information to take in but Im starting to get the grasp
5 to 7
on this day I finished the defines.h file

3 to 4
on this day I started on the enums.h file
this initializes the block types and the dirctions of the blocks
#pragma once
enum BlockType
{
SQUARE_BLOCK,
T_BLOCK,
L_BLOCK,
BACKWARDS_L_BLOCK,
STRAIGHT_BLOCK,
S_BLOCK,
BACKWARDS_S_BLOCK
};
enum Direction
{
LEFT,
RIGHT,
DOWN
};
5 to 6
on this day I worked on the cSquare.h file, this is to individualize the blocks within the shapes so its easier for the collision detection
5 to 7
on this day I continued with the cSquare.h file, getting pretty close to done with it, I am getting a good understanding of the information
530 to 7
on this day I finished cBlock.h file
#pragma once

cBock.h cBlock class will store its center, type, and the four squares that it's built from.
SetupSquares() initializes the locations of the block's squares with respect to its center.
cBlock's Draw() method simply calls the Draw() methods of its squares. Its Move() method just changes its center variables and then calls its squares' Move() methods.

on this day I started the main function, this includes: collision detection, initialization of the screen, background, shape movement, etc
about 18 hours all togther
I have been working on and off on the main function and it is confusing as hell, so I am researching alot and finding alot of good things about the functions and why they are used but its coming along and will be done soon and of course the god damn collision detection is kicking my ass!! I am typing the code in manually.
5pm to 8pm
