how to increase the length of a string

#include <iostream>
#include <string>

int main() {
    std::string myString = "Hello";

    // Step 1: Determine the desired length increase
    int increaseLength = 5;

    // Step 2: Use the append function to increase the length of the string
    myString.append(increaseLength, ' '); // Appends 'increaseLength' spaces

    // Step 3: Print the modified string
    std::cout << "Modified String: " << myString << std::endl;

    return 0;
}
