What's wrong with this code? It's not asking for entering character. I'm unable to input any character.

Question

#include <stdio.h>
void main(){
float num1,num2;
char ch;
printf("Enter the numbers:");
scanf("%f %f", &num1, &num2);
printf("Enter operation:");
scanf("%c", &ch);

switch(ch){
case '+':
printf("%f",num1+num2);
break;

case '-':
printf("%f",num1-num2);
break;

case '*':
printf("%f",num1*num2);
break;

case '/':
printf("%f",num1/num2);
break;

}
}

Answer 1

Add a space before the %c format specifier, as follows:

scanf (" %c", &ch);

What happens here is that we have a '\n' character in the input stream from previous input (when reading <num1> & <num2>). By adding the space before %c specifier the '\n' character it will work.

Good luck!
