In this program, You will learn how to perform arithmetic operations using switch case in C++.

```
Enter your choice = 1
10 + 10 = 20
```

## Example: How to perform arithmetic operations using a switch case in C++.

```
#include<iostream>
using namespace std;
int main() {
int x, y, res;
int ch;
cout << "Enter 1 For Addition :";
cout << "\nEnter 2 For Subtraction :";
cout << "\nEnter 3 For Multiplication :";
cout << "\nEnter 4 For Division :";
cout << "\nEnter 5 For Modulus :"<<endl;
cin >> ch;
switch (ch) {
case 1:
{
cout << "Enter Two Numbers :";
cin >> x >> y;
res = x + y;
cout << "\nResult is :" << res;
break;
}
case 2:
{
cout << "Enter Two Numbers :";
cin >> x >> y;
res = x - y;
cout << "Result is :" << res;
break;
}
case 3:
{
cout << "Enter Two Numbers :";
cin >> x >> y;
res = x * y;
cout << "Result is :" << res;
break;
}
case 4:
{
cout << "Enter Two Numbers :";
cin >> x >> y;
res = x / y;
cout << "Result is :" << res;
break;
}
case 5:
{
cout << "Enter Two Numbers :";
cin >> x >> y;
res = x % y;
cout << "Result is :" << res;
break;
}
}
return 0;
}
```

#### Output:

```
Enter 1 For Addition :
Enter 2 For Subtraction :
Enter 3 For Multiplication :
Enter 4 For Division :
Enter 5 For Modulus :
2
Enter Two Numbers :10 2
Result is :8
```
