Program to demo arithmetic calculator using switch
#include<stdio.h>
void main()
{
int a, b;
float res;
char op;
printf("\nEnter a op b :");
scanf("%d %c %d", &a, &op, &b);
switch(op)
{
case '+' : res = a+b;
break;
case '-' : res = a-b;
break;
case '*' : res = a * b;
break;
case '/' : if(!b)
printf("\n Divide by zero error");
else
res = (float)a/b;
break;
case '%' : res = a % b;
break;
default: printf("\nGive valid operator+");
break;
}
printf("\n Result = %f", res);
}
Output:
Enter a op b : 1 / 2
Result = 0.500000
