Calculation of two user entered numbers

If the user enters A then we will go for addition of two numbers.
If the user enters B then we will go for subtraction of two numbers 
If the user enters C then we will go for multiplication of two numbers
If the user enters D then we will go for division of two numbers 

#include <stdio.h>
int main(void){
char var;
int num1,num2,v;
printf(" Please enter A, B, C or D \n");
var=getchar();
printf("Enter the two numbers ");
scanf("%d %d",&num1,&num2); // Enter two numbers
switch(var)
{
case 'A':

v=num1+num2;
printf("Sum of two numbers are  ");
printf("\n");
printf("%d",v);
break;

case 'B':
v=num1-num2;
printf("Subtraction of two nmbers are  ");
printf("\n");
printf("%d",v);
break;

case 'C':
v=num1*num2;
printf("Mulitplication of two numbers are ");
printf("\n");
printf("%d",v);
break;

case 'D':
v=num1/num2;
printf("Division of two numbers are ");
printf("\n");
printf("%d",v);
break;

default:
printf("You entered section ");
 }
return 0;
