BASIC CALCULATOR

Write a C program to simulate a basic calculator. [+,-,*,/,%]. Use switch statement.

Input Format:
The first line of the input consists of an integer which corresponds to a. The second line of the input consists of a character which corresponds to the operator. The third line of the input consists of an integer which corresponds to b.

Output format: Output consists of a single line [a op b]. Refer to sample output for details.

Sample Input 1:
3
+
5

Sample Output 1:
The sum is 8

Sample Input 2:
7
-
6

Sample Output 2:
The difference is 1

Sample Input 3:
4
*
3

Sample Output 3:
The product is 12

Sample Input 4:
12
/
3

Sample Output 4:
The quotient is 4

Sample Input 5:
4
%
2

Sample Output 5:
The remainder is 0

Sample Input 6:
5
^
2
Sample Output 6:
Invalid Input

Code:

  #include<stdio.h>
int main()
{
  int a,b;
  char o[1];
  scanf("%d",&a);
  scanf("%s",o);
  scanf("%d",&b);
  switch(o[0])
  {
    case '+':
          printf("The sum is %d",a+b);
          break;
    case '-':
          printf("The difference is %d",a-b);
          break;
    case '*':
          printf("The product is %d",a*b);
          break;
    case '/':
          printf("The quotient is %d",(int)(a/b));
          break;
    case '%':
          printf("The remainder is %d",(int)(a%b));
          break;
    default:
    printf("Invalid Input");
    break;
    
  }
  return 0;
}
