Example: Sort Names using std::sort in C++

// Sort Names using std::sort
#include <iostream>  // For input/output operations
#include <vector>    // For using std::vector to store names
#include <string>    // For using std::string objects
#include <algorithm> // For the std::sort function

int main() {
    // Step 1: Declare a vector of strings to store names
    std::vector<std::string> names;
    std::string name;
    int numNames;

    // Step 2: Get the number of names from the user
    std::cout << "Enter the number of names you want to sort: ";
    std::cin >> numNames;
    std::cin.ignore(); // Consume the newline character left by std::cin >> numNames

    // Step 3: Read names from the user
    std::cout << "Enter " << numNames << " names:\n";
    for (int i = 0; i < numNames; ++i) {
        std::cout << "Name " << i + 1 << ": ";
        std::getline(std::cin, name); // Read full line including spaces
        names.push_back(name);
    }

    // Step 4: Sort the names using std::sort
    // std::sort works directly on std::string objects, comparing them alphabetically
    std::sort(names.begin(), names.end());

    // Step 5: Print the sorted names
    std::cout << "\nNames in alphabetical order:\n";
    for (const std::string& sortedName : names) {
        std::cout << sortedName << std::endl;
    }

    return 0;
