Operators are symbols that specify some kind of operation. In C++, we sometimes need to take operators as user input mainly to perform mathematical operations. In this article, we will learn how to take operators as user input in C++.

Operators as Input in C++

To take operators (like +,-,*,/ etc) as user input, we can use a char datatype to read the operator as a character using cin and then validate whether the entered operator is valid or not using a switch or conditional statements.

C++ Program to Take Operator as Input

The below example demonstrates how we can take the operator as user input, validate it, and perform mathematical calculations.

Output

Enter the first number: 8   
Enter the second number: 2
Enter the arithmetic operator (+, -, *, /): /
Result: 4
