Vincent Cordes Spring 2012 Opus

This is the last year of the world (so they say)

Introduction

Looking forward to another fun semester.

Part 1

Entries

Entry 1: January something, 2012

  • What action or concept of significance, as related to the course, did you experience on this date?
  • Pointers
  • Why was this significant?
  • Pointers as Matt says give C a lot of its power making it mo better
  • What concepts are you dealing with that may not make perfect sense?
  • The concepts make sence
  • What challenges are you facing with respect to the course?
  • I need to make some time to practice and play with the things I'm learning

Entry 2: January something, 2012

  • What action or concept of significance, as related to the course, did you experience on this date?
  • Malloc, and the various memory allocating tools
  • Why was this significant?
  • It makes C mo better
  • What concepts are you dealing with that may not make perfect sense?
  • The implementation of them is a bit difficult
  • What challenges are you facing with respect to the course?
  • Using these tools can be a bit tricky…also what is the long term purpose of them…why not just set variables within a program since there is a limited amount of space that can be allocated anyway

Entry 3: February 16, 2012

  • What action or concept of significance, as related to the course, did you experience on this date?
  • Putting together a program from a combination of things that we have learned so far
  • Why was this significant?
  • It was a good test of what I have learned and my ability to put everything together
  • What concepts are you dealing with that may not make perfect sense?
  • Everything makes sense
  • What challenges are you facing with respect to the course?
  • It ended up being a simple yet difficult project at the same time. More practice I think will be key to becoming efficient.

Entry 4: January Day, 2012

This is a sample format for a dated entry. Please substitute the actual date for “Month Day, Year”, and duplicate the level 4 heading to make additional entries.

As an aid, feel free to use the following questions to help you generate content for your entries:

  • What action or concept of significance, as related to the course, did you experience on this date?
  • Why was this significant?
  • What concepts are you dealing with that may not make perfect sense?
  • What challenges are you facing with respect to the course?

Remember that 4 is just the minimum number of entries. Feel free to have more.

Keywords

cprog Keywords

Pointers

Since this seems to be a biggie I guess I will start here.

Definition

A pointer is a tool that “points” you to a block of memory and allows access to the data contained within.

Demonstration

Demonstration of the chosen keyword.

If you wish to aid your definition with a code sample, you can do so by using a wiki code block, an example follows:

#include<stdio.h>
#include<stdlib.h>
int main( )
 
{
        int *p1, *p2, p3, **p4;
        p1=(int *)malloc(sizeof(int)*1);
        *p1=26;
        printf("*p1 is %u\n", *p1);
        p2=p1;
        p4=&p1;
        printf("**p4 is %u\n", **p4);
        printf("*p2 is %u\n", *p2);
        *p2=61;
        return(0);
}

File Access (Read, Write, Append)

Matt withheld some info saying something about the force not being strong enough to do everything I want to be capable of with this topic but I will get there.

Definition

File Access is the ability of C to “access a file.” (crazy how these things kind of define themselves) Essentially you can pull a file into C to Read it, create a file and write it, or append the file (make changes). On a side note if you intend to open a file via C you must also close the file.

Demonstration
#include<stdio.h>
#include<stdlib.h>
 
int main()
{
        FILE *in, *out;
        char value=0;
        in=fopen("file.txt", "r");
        out=fopen("out.txt", "w");
        if (in == NULL)
        {
                printf("ERROR!\n");
                exit(1);
        }
        fscanf(in, "%hhd", &value);
        while(value !=-1)
        {
                value *=2;
                fprintf(out, "%hhd\n", value);
                fscanf(in, "%hhd", &value);
        }
        fclose(in);
        fclose(out);
        return(0);
}

Arithmetic (equations, operators)

Definition

C can do math. Math can be done in C. operators being +-/* as they would be with math and equations working the same as would be expected.

Demonstration
#include <stdio.h>
#include <stdlib.h>
 
int main()
{
    int a=1;
    int b=5;
    int c=(a+b);
    printf("%d", c);
    return(0);
}

cprog Objective

cprog Objective

State the course objective

Definition

In your own words, define what that objective entails.

Method

State the method you will use for measuring successful academic/intellectual achievement of this objective.

Experiments

Experiment 1

Question

Curious as always I want to know how closely C and C++ are related. If I take an existing(working) C program and try to compile it with a C++ compiler will it compile, and furthermore will it work.

Resources

Hypothesis

I believe it will work flawlessly…or not I don't know if the syntax is the same, I am sure however that the libraries are universal.

Experiment

How are you going to test your hypothesis? What is the structure of your experiment?

Data

It worked easily and flawlessly with the proper output.

Analysis

Based on the data collected:

  • Was your hypothesis correct?
  • Aye and Nay I didn't know what would happen
  • Was your hypothesis not applicable?
  • It was applicable
  • Is there more going on than you originally thought? (shortcomings in hypothesis)
  • Perhaps but I didn't come across it.
  • What shortcomings might there be in your experiment?
  • I used a relatively simple program I can't be certain that there wouldn't have been a problem with something more complex
  • What shortcomings might there be in your data?
  • None that I can see

Conclusions

I can be sure that anything C can do C++ can do as well.

Experiment 2

Question

What is the question you'd like to pose for experimentation? State it here.

Resources

Collect information and resources (such as URLs of web resources), and comment on knowledge obtained that you think will provide useful background information to aid in performing the experiment.

Hypothesis

Based on what you've read with respect to your original posed question, what do you think will be the result of your experiment (ie an educated guess based on the facts known). This is done before actually performing the experiment.

State your rationale.
