Can anyone explain why this code is not working..? 🙄

Question

#include <stdio.h>
#include <stdint.h>
int main()
{
float num1;
float num2;
char op;
float result;

printf("Enter first value :");
scanf("%f",&num1);

printf("Enter operator :");
scanf("%c",&op);

printf("Enter second value :");
scanf("%f",&num2);

switch(op)
{
case '+' :
result = num1+num2;
printf("%f",result);
break;
case '-' :
result = num1-num2;
printf("%f",result);
break;
case '*' :
result = num1*num2;
printf("%f",result);
break;
case '/' :
result = num1/num2;
printf("%f",result);
break;
}
return 0;
}

Answer 1

Add a space prior to %c to consume the remaining whitespace character from the previous scanf.
scanf(" %c",&op);

Answer 2

Try using #include<stdlib> in place of <stdint> it works.. you can refer this..made some changes :)
