Raesel's Opus

Spring Semester 2012

Introduction

This is my second course here at the lair and I am looking forward to it. I am still a computer science major with interest in software engineering and, more enthusiastically, aerospace engineering. My status is a freshmore here at CCC. I do plan to transfer to a four year school for my bachelor degree and possibly look into getting my masters degree.

Random information about me: I like to wear fedora hats and you will almost never see me without one. I am passionate about movies and and embarking on an adventure to rewrite Macbeth and make it into a movie. I like to bake and occasionally cook savory foods. I do enjoy listening to music… on occasion. I love to travel to exotic locales. I am also an avid couch potato.

Part 1

Entries

Entry 1: January 31, 2012

Today we played more with pointers. We wrote another program which delved into the realm of double pointers. I think I understand pointers but I may be over-simpplifing them. Esssentialy, they direct the computer to another location. When called to give the information contained in them they return the value of what they are pointing to.

Entry 2: Febrauary 2, 2012

Todday we wrote a game in class. We used some elements of things that we used in previous classes as well as looked into loops. We also looked at the rand function which is supposed to resemble a random number generator but doesn't do it very well. We did go through and fix the problem which did make it more random. We also added a loop into the code which looped the game until the user decides to quit. I understand this program and what it is doing, which is a good sign. I haven't gotten lost in the class yet which is always a hopeful start.

Entry 3: February 7, 2012

Today we looked at arrays. My previous experince with arrays is limited to the theoretical realm. I understood that arrays needed to be sized before you start to fill them but I never was quite sure how to actually create them in a program. Today's class helped. I am still not 100% comfortable with creating them on my own but I do see how it can be done.

Entry 4: February 25, 2012

Today Project 1 was due and it was rather more challenging than previously thought. I understand the logic of how to do the program and I understand what needs to be done on the project, however, I am struggling with the actual implementation of the code. When I sit to write the code I essentially draw a blank and have no idea where to begin. I believe that if I sit down more with a pseudocode and play more with syntax and read source material on how to code in C I can overcome this dilemma. Otherwise, this will be a very difficut semester.

cprog Objective

cprog Objective

comprehend the basics of memory management, data representation and storage

Definition

Can the student understand how to allocate memory and represent what they wish to represent with the proper file type? Does the student understand how to store values in C?

Method

Explain the code of project 0

Measurement

The code of project 0 is defining the size of the storage available for the different types of arguments in C. Each storage size dictates how much memory needs to be allocated for that type and whether or not datat will fit into that storage type.

Analysis

I understand the logic behind most codes but will need to continue to work on writing the actual code.

Experiments

Experiment 1

Question

Can a program check the upper and lower bounds

Resources

Class notes and book

Hypothesis

Yes. The program can check the upper

Experiment

Write a code

Data

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char **argv)
{
        signed int input;
        char column=0;
        char row=0;
        printf("Enter a value (0-4): ");
        scanf("%d", &input);
        while((input<4) && (input>0))
        {
                printf("argv[%hhu]: %c\n", input, *(*(argv+row)+column));
                printf("You ran this program with %hhu arguments, they are:\n",argc);
                exit(1);
        }


        printf("You have input an invalid value\n");

        return(0);
}

Analysis

I know that the code should work but I am unable to get the right syntax to compile it.

Conclusions

I need to spend more time learning syntax.

Experiment 2

Question

What happens if you put a semicolon on the end of a loop statement

Resources

the book was consulted

Hypothesis

The program won't compile

Experiment

I will add a semicolon on the end of a loop statement in a program and see what happens

Data

The program didn't compile. The loop statement was treated like another regular statement in the program which threw the whole program off.

Analysis

The hypothesis was correct although I could have gone much further into figuring out why it would not compile. The hypothesis short cited and lacks depth.

Conclusions

Although the program behaved as expected it could have been explore further.

Experiment 3

Question

What types of things create a segmentation fault

Resources

class programs and book

Hypothesis

Faulty syntax will cause a seg fault

Experiment

Play with codes already written

Data

I found that mainly a logic error in the loops will give a seg fault

Analysis

Based on the data collected: The hypothesis was not entirely correct. The hypothesis was very vague as was the question posed. If The hypothesis could have been slightly more specific the experiment might have had a little more guidance.

Conclusions

The main cause of segmentation faults are logic errors but logic errors also lead to other types of problems within the program.

Part 2

Entries

Entry 5: March 6, 2012

Today we covered a couple of new pieces of material in class. The first of which is a typedef which renames something to be more easily referenced in the code. The other was a union. The thing to remember about unions is that they are like an array but can have different data types within whereas an array can only have one data type. The union can be useful only if the things inside of it need not be used at the same time.

The other brief lesson was on struct which is similar to a union but different. A struct does not share memory space like a union but instead creates memory for each but you still need to allocate.

Entry 6: March 20, 2012

Today I caught up on some of the things I missed the previous week. One of these concepts was multifile and inheritance. We set up codes in different code sets and then linked them all together. This is multifile. It isn't terribly difficult but it does require some thinking especially if writing header files to be incuded in the different code blocks that will be used for inheritance. I think I mostly understand how it works but making sure I have defined everything is going to be my biggest challenge. Also making sure that I i define the header files properly and include them using the right syntax will also be something to keep an eye out for.

Entry 7: March 22, 2012

This day in class history we talked about cin, cout, and cerr. It became clear that to use cout would take a lot more syntax than using a printf statement. Conversely, it takes a little less to use a cin statement instead of a scanf statement. We also played around a little more with multifiles and gates. Gates are an interesting concept that I need to explore further in how to set them up properly.

Entry 8: March 29, 2012

Inheritance was the topic of the day. We focused mostly on perfecting it and understanding the concept behind it. I do understand it and I am fairly confident that the next topic of polymorphism will confound but not completely baffle with no ray of sunshine.

Definition

typedef: rename function in code aka alias union: a container that can contain more than one data type. it allocates memory to the largest data type within and only works with one data type at a time. can only be used when the things inside need not be used at the same time

Demonstration
#include <stdio.h>
#include <stdlib.h>
 
int main()
{
     int i;
     union var{
          int x;
          float f;
     };
     typedef union var Uif;
     Uif value;
     value.x=0;
     for(i=0; i<24; i++)
     {
          value.x=value.x+rand()%51+1;
     }
     printf("total is %d\n", value.x);
     for(i=0; i<73; i++)
     {
          value.f=value.f+rand()%27+0.1;
     }
     printf(total is %f\n, value.f);
     }
     return(0);
}

Structures

Declarations, Accessing Elements, Pointers to

Definition

basically the same as a union except it will allocate memory for each member but does not share memory

Demonstration
#include <stdio.h>

int main()
{
     struct person{
     char *name;
     unsigned char age;
     short int weight;
     float gpa;
     };
     return(0);
}

This is the setup for a struct based on characteristics of a person

cprog Objective

cprog Objective

Distinguish and explain the difference between homogeneous and heterogeneous composite data types

Definition

Can the student correctly identify a homogeneous composite data type and a heterogenous composite data type?

Method

Write a code for both a heterogeneous and homgeneous containers

Measurement

<code> #include <stdio.h>

int main() {

   struct time{
        float sec;
        char min;
        int hour;
        short int day;
   };
   
   long int century[20]
   return(0);

}

Analysis

This is not a complete view of the code but it does show the difference in how each of these types are set up. The struct allocated memory for each of the elements within and accessed them. There are many different data types within the struct. When trying to add different data types to the array century the compiler will not allow because it only a long int can go into century. The array is homogeneous and the struct is heterogeneous.
