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 Keyword 4

Identification of chosen keyword (unless you update the section heading above).

Definition

Definition (in your own words) of the chosen keyword.

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:

/*
 * Sample code block
 */
#include <stdio.h>
 
int main()
{
    return(0);
}

Alternatively (or additionally), if you want to demonstrate something on the command-line, you can do so as follows:

lab46:~$ cd src
lab46:~/src$ gcc -o hello hello.c
lab46:~/src$ ./hello
Hello, World!
lab46:~/src$
