how to make sure the user inputs a int and not anything else c++

To ensure that the user inputs an integer and not any other type of input in C++, you can use the std::cin function along with the >> operator to read user input as an integer. Here are the steps to achieve this:

1. Include the necessary header file: cpp #include <iostream>

2. Declare a variable of type int to store the user's input: cpp int userInput;

3. Prompt the user for input: cpp std::cout << "Enter an integer: ";

4. Read the user's input using std::cin: cpp std::cin >> userInput;

5. Check if the input was successful and if the next character in the input stream is a newline character ('\n'): cpp if (std::cin.fail() || std::cin.peek() != '\n') { // Input was not an integer std::cout << "Invalid input. Please enter an integer." << std::endl; // Clear the input stream std::cin.clear(); // Discard the remaining characters in the input stream std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n'); // Handle the error or ask for input again } else { // Input was an integer // Proceed with further processing }
