Finding the arithmetic operators

Below is a very simple program to find the arithmetic operator.
Please feel free to put a comment if need an explanation.





#include
#include


void main()
  {
    float a1,a2;
    char operator;
    printf("\n Enter the values of a1 operator a2\n");
    scanf("%f%c%f",&a1,&operator,&a2);
    switch(operator)
     {
case '+':
printf("%.2f",a1+a2);
break;
case '-':
 printf("%.2f",a1-a2);
 break;


case '*':
 printf("%.2f",a1*a2);
break;
case '/':
 if(a2==0)
 printf("error\n");
 else
 printf("%.2f",a1/a2);
 break;
default: printf("unknown operatotr\n");
break;
     }
   }
