C program to perform arithmetic operations using switch case

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>

void main()
{
int ch;
float a,b,res;
clrscr();
printf("Enter two numbers:");
scanf("%f%f",&a,&b);
printf("
Menu
1.Addition
2.Subtraction
3.Multiplication
4.Division");
printf("
Enter your choice:");
scanf("%d",&ch);

switch(ch)
{
case 1: res=a+b;
break;
case 2: res=a-b;
break;
case 3: res=a*b;
break;
case 4: res=a/b;
break;
default: printf("Wrong choice!!
Press any key...");
getch();
exit(0);
}

printf("
Result=%f",res);
getch();
}

C Program to perform all arithmetic calculation using switch case

#include<iostream.h>
#include<conio.h>

cout<<"Arithmetic Operatios";
cout<<"

1.Addition
2.Subtraction
3.Multiplication
4.Division
5.Mode";
cout<<"
Enter your choice:";
cin>>ch;

switch(ch)
{
case 1:
{
cout<<"

Enter two variables:";
cin>>a>>b;
res=a+b;
cout<<"
Result="<<res;
}
break;

case 2:
{
cout<<"

Enter two variables:";
cin>>a>>b;

Enter two variables:";
cin>>a>>b;

Enter two variables:";
cin>>a>>b;
if(a>=b)
{
res=a/b;
cout<<"
Result="<<res;
}
else
cout<<"

1st varable should be greater than 2nd.!!!";
}
break;

case 5:

Enter two variables:";
cin>>a>>b;
