Here we will develop a C++ program for addition subtraction multiplication and division operations.
following are the arithmetic operations in C++ programming.
| Sr No | Operator | Symbol | Example |
|---|---|---|---|
| 1 | Addition | + | int result = num1 + num2; |
| 2 | Subtraction | – | int result = num1 - num2; |
| 3 | Multiplication | * | int result = num1 * num2; |
| 4 | Division | / | double result = num1 / num2; |
| 5 | Modulo | % | int result = num1 % num2; |
| 6 | Increment | ++ | num++; |
| 7 | Decrement | — | num--; |

Output
Menu Driven addition subtraction multiplication and division with error handling
following is a menu-driven program for C++ to perform addition, subtraction, multiplication and division also handles exceptions where the denominator is zero in the division operation.
