    How do integers get written to files?

    Compile as usual:

        gcc -Wall -Werror -g -o integer_rep integer_rep.c

    Run with no command-line arguments:

        ./integer_rep
*/
#include <stdio.h>

// Use fwrite and fprintf to output integers
int main()
{
    // Write ints with fwrite -- this outputs the actual integer,
    // not the string representation of it
    int j = 25;
    fwrite(&j, sizeof(int), 1, stdout);

    j = 0xABCDE;
    fwrite(&j, sizeof(int), 1, stdout);

    // Write ints with fprintf and the %d format specifier --
    // this outputs the string representation, not the actual integer
    fprintf(stdout, "\t\t\t"); // add some blank space (tabs)
    fprintf(stdout, "0x%X", j);
    fprintf(stdout, "\n");

    return 0;
