Write a code according to the statement and execute the operation according to the user's choice. We can also use these programming statements as a C++ program to make a simple calculator to add, subtract, multiply or divide using a switch case.

## C++ Program to Perform Arithmetic Operations Using Switch Case

```
#include <iostream>
using namespace std;
int main()
{
/*C++ program for addition, subtraction, multiplication and division using switch case */
float a, b, rem;
int ch, q;
cout << "Arithmetic Operatios";
cout << "\n1.Addition\n2.Subtraction\n3.Multiplication\n4.Division\n5.Mode";
cout << "\n\nEnter Your Choice:\n";
cin >> ch;
switch (ch)
{
case 1:
{
cout << "\nEnter Two Value Ie:- Value Of A And B ";
cin >> a >> b;
rem = a + b;
cout << "\n Result = " << rem;
cout << "\n";
}
break;
case 2:
{
cout << "\nEnter Two Value Ie:- Value Of A And B";
cin >> a >> b;
rem = a - b;
cout << "\n Result = " << rem;
cout << "\n";
}
break;
case 3:
{
cout << "\nEnter Two Value Ie:- Value Of A And B";
cin >> a >> b;
rem = a * b;
cout << "\n Result = " << rem;
cout << "\n";
}
break;
case 4:
{
cout << "\nEnter Two Value Ie:- Value Of A And B";
cin >> a >> b;
if (a >= b)
{
rem = a / b;
cout << "\n Result = " << rem;
cout << "\n";
}
else
cout << "\nt 1st Varable Should Be Greater Than 2nd. !!!";
cout << "\n";
}
break;
case 5:
{
cout << "\nEnter Two Value Ie:- Value Of A And B";
cin >> a >> b;
if (a >= b)
{
q = a / b;
rem = a - (b *q);
cout << "\n Result = " << rem;
cout << "\n";
}
else
cout << "\nt 1st Varable Should Be Greater Than 2nd. !!!";
cout << "\n";
}
break;
}
return 0;
}
```
