The below program uses the "+" operator to concatenate the two strings together but I would like to use the append() function to do the task. How would that be implemented? Please and Thank you C++ source code: // Necessary header files #include <iostream> #include <string>   // Function to concatenate the strings together std::string concatenateStrings(const std::string& str1, const std::string& str2) { return str1 + str2; }   int main() { // Loop to take user's input three times for (int i=0; i <3; ++i) { // Prompt user for first string input std::cout << "Please enter a string: "; std::string input1; std::getline(std::cin, input1); // Allowing spaces in input   // Prompt user for second string input std::cout << "Please enter another string: "; std::string input2; std::getline(std::cin, input2); // Allowing spaces in input   // Concatenate the strings std:: string result = concatenateStrings(input1, input2);   // Print the concatenated result std::cout << "Your concatenated string result: " << result << "\n\n";   } return 0; }

Question

The below program uses the "+" operator to concatenate the two strings together but I would like to use the append() function to do the task. How would that be implemented?

Please and Thank you

C++ source code:

// Necessary header files

#include <iostream>

#include <string>

 

// Function to concatenate the strings together

std::string concatenateStrings(const std::string& str1, const std::string& str2) {

return str1 + str2;

}

 

int main() {

// Loop to take user's input three times

for (int i=0; i <3; ++i) {

// Prompt user for first string input

std::cout << "Please enter a string: ";

std::string input1;

std::getline(std::cin, input1); // Allowing spaces in input

 

// Prompt user for second string input

std::cout << "Please enter another string: ";

std::string input2;

std::getline(std::cin, input2); // Allowing spaces in input

 

// Concatenate the strings

std:: string result = concatenateStrings(input1, input2);

 

// Print the concatenated result

std::cout << "Your concatenated string result: " << result << "\n\n";

 

}

return 0;

}
