C Program - Write a program, which accepts two integers and an operator as a character (+ - * /), performs the corresponding operation and displays the result

Program

#include<stdio.h>
int main()
{
  int a,b,res;
  char c;

  printf("\n Enter any one operator +, -, *, / :");
  scanf("%c",&c);
  switch(c)
  {
    case '+':
printf("\n Enter two numbers: ");
    scanf("%d%d",&a,&b);
res=a+b;
    printf("\n The sum is %d",res);
    break;
    case '-':
printf("\n Enter two numbers: ");
    scanf("%d%d",&a,&b);
res=a-b;
    printf("\n The difference is %d",res);
    break;
    case '*':
printf("\n Enter two numbers: ");
    scanf("%d%d",&a,&b);
    res=a*b;
    printf("\n The product is %d",res);
    break;
    case '/':
printf("\n Enter two numbers: ");
    scanf("%d%d",&a,&b);
    res=a/b;
    printf("\n The quotient is %d",res);
    break;
    default: printf ("\n Invalid entry");
  }
}

Output:

 Enter any one operator +, -, *, / :*

 Enter two numbers: 6 4

 The product is 24
