Question

How do I limit the length of the user input string?

Answer 1

If you want to limit the length of the user input string, you can manually check the length and take appropriate action. 

Here's an example code snippet:

#include <iostream>
#include <string>

int main() {
    std::string name;
    
    std::cout << "Enter your name (up to 10 characters): ";
    std::getline(std::cin, name);
    
    if (name.length() > 10) {
        std::cout << "Name exceeds the limit." << std::endl;
    } else {
        std::cout << "Hello, " << name << "!" << std::endl;
    }
    
    return 0;
}
 

In this example, the code checks if the length of the input string is greater than 10 characters and displays an error message if it is.
