First Program in C

Now that I’ve got Ruby and Rails fairly well learned and practiced, I decided it was time to start working towards my long term goal of blending my programming skills with my love of art. Here is my first baby step towards learning C:

touch foo.c

mate foo.c

In foo.c I wrote (with the help of my roommate Sean):

`#include <stdio.h> int main() {

int i;
printf("Hello World!!!!!!\n");
for(i=0; i<5; i++) {
    printf("%d\n", i);
}
return 0;

Next, I compiled my program:

gcc foo.c

This created a file called a.out

Next I ran a.out

./a.out

And it out put:

Hello World!!!!!! 0 1 2 3 4

Sean also taught me how to define the name of the out file:

gcc -o foo foo.c

This let me do the following to execute my program:

./foo
