scanf() misbehaving

Question

I have a very short snippet that reads in an integer:

#include 

int main() {
    while (1) {
        int i = 0;
        int r = scanf(\"%d\",         


        

Answer 1

Sounds like you are not clearing the input buffer and leaving the incorrect char to be scanned over and over.

scanf not terminating
