Write a Line to stdout with fputs
The donation counter already has its message. fputs(text, stdout) sends it to normal output exactly as written; it does not supply a newline. This example writes to stdout, not to a local file.
c
#include <stdio.h>
int main(void) {
fputs("Donations ready\n", stdout);
return 0;
}
Run it, then remove \n from the string and compare where the next terminal prompt appears. Put the newline back to keep the notice on its own line.
