The following yields incorrect result when characters are inputed instead of integers. import stream; int main() { const int answer = 10; int guess; printf("Pick a number: "); scanf("%d", &guess); if(answer == guess) { printf("Answer = %d.", guess); } else if(answer > guess) { printf("Answer > guess."); } else if(answer < guess) { printf("Answer < guess."); } else { printf("That wasn't a number."); } return 0; }

If you change "guess" to a float, I think it works as expected. Apparently, integers default to 0 when a non-number is given. Try this: import stream; int main() { const int answer = 10; float guess; printf("Pick a number: "); scanf("%f", &guess); if(answer == guess) { printf("Answer = %f.", guess); } else if(answer > guess) { printf("Answer > guess."); } else if(answer < guess) { printf("Answer < guess."); } else { printf("That wasn't a number."); } return 0; } Andrew Edwards wrote:The following yields incorrect result when characters are inputed instead of integers. import stream; int main() { const int answer = 10; int guess; printf("Pick a number: "); scanf("%d", &guess); if(answer == guess) { printf("Answer = %d.", guess); } else if(answer > guess) { printf("Answer > guess."); } else if(answer < guess) { printf("Answer < guess."); } else { printf("That wasn't a number."); } return 0; }
