C Programming Tutorial - 50 - Writing Files in C

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

int main()
{
    //files allow you to save data even when you shut off your computer
    //sequential access files - must write your data in order
    //random access files - can store data all over

    //need this to keep track of where you are in your file
    FILE * fPointer;

    //now we need to open a file to point to
    //w - write (aka create) a new file
    //r - read from a file
    //a - append (aka add on to) end of existing file
    fPointer = fopen("bacon.txt", "w");

    fprintf(fPointer, "I love cheese\n");

    //if you run this again, it will overwrite the old file

    fclose(fPointer);

    return 0;
