Arithmetic operations using function and switch case

This program uses function to perform the selected mathematical operation. Here switch case is used to select the options.

 

#include<stdio.h>
#include<conio.h>
int res;
int sum(int x,int y);
int sub(int x,int y);
int mul(int x,int y);
int div(int x,int y);
int main()
{
    int choice,a,b;
    printf("select anyone of the following operation\n");
    printf("1.addition\n2.subtraction\n3.multiplication\n4.division\n");
    scanf("%d",&choice);
    printf("enter the two values");
    scanf("%d%d",&a,&b);
    if(choice==1)
    printf("sum is %d\n",sum(a,b));
    else if(choice==2)
    printf("difference is %d",sub(a,b));
    else if(choice==3)
    printf("product is %d",mul(a,b));
    else if(choice==4)
    printf("quotient is %d",div(a,b));
    else
    printf("not a valid choice");
    getch();
}
int sum(int x,int y)
{
    res=x+y;
    return res;
}
int sub(int x,int y)
{
    res=x-y;
    return res;
}    
int mul(int x,int y)
{
    res=x*y;
    return res;
}
int div(int x,int y)
{
    res=x/y;
    return res;
}
    

output

select anyone of the following operation
1.addition
2.subtraction
3.multiplication
4.division
1
enter two values
2
4
sum is 6
