This is a code snippet from my program:
#include <stdbool.h>
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
double get_number()
{
double num;
int result;
do
{
printf("Enter number: ");
result = scanf("%lf", &num);
} while (result != 1);
return num;
}
When the user does not enter a number, I expected the program to simply ask for inout again, but instead, it just does this:
"Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: Enter number: ^C"
until I end the program manually. What's wrong?
I tried used fflush(stdin), but to no avail. I really don't know where to start.
