Created page with "FIle library.c: <source lang=c> // library.c #include <stdio.h> #include <stdlib.h> void foo(int x) { printf("foo(%d)\n", x); } int main(int argc, char **argv) { if..."

New page

FIle library.c:

<source lang=c>
// library.c
#include <stdio.h>
#include <stdlib.h>

void foo(int x) {
printf("foo(%d)\n", x);
}

int main(int argc, char **argv) {
if (argc != 2) {
fprintf(stderr, "USAGE: %s n\n", argv[0]);
exit(1);
}
foo(atoi(argv[1]));
return 0;
}
</source>
