I have just read atoi() returns no errors. It returns an int though and
the value of the int is supposed to be the value of the conversion. It seems
to me that right there tells you if there was success or not. Am I wrong?
Yes.
Take a look at the following program and tell me how you'd detect an
error in a call to atoi().
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
char *good = "0";
char *bad = "bad";
printf("atoi(\"%s\") = %d\n", good, atoi(good));
printf("atoi(\"%s\") = %d\n", bad, atoi(bad));
return 0;
}
