C++ search with cin

 

Conversation wit

Here is a complete C++ code sample that initializes an array of 5 names, takes input using std::cin >>, and searches for the name using std::find from the <algorithm> header:

C++

#include <iostream>
#include <string>
#include <algorithm> // Required for std::find
#include <iterator>  // Required for std::begin and std::end

int main() {
    // 1. Array of 5 names
    std::string names[5] = {"Alice", "Bob", "Charlie", "Diana", "Ethan"};

    // 2. Get input from user using std::cin
    std::string targetName;
    std::cout << "Enter a name to search for: ";
    std::cin >> targetName;

    // 3. Search using std::find from <algorithm>
    // std::find returns an iterator pointing to the found element, or std::end if not found.
    auto result = std::find(std::begin(names), std::end(names), targetName);

    // 4. Output the result
    if (result != std::end(names)) {
        // Find the index by calculating distance from the beginning
        int index = std::distance(std::begin(names), result);
        std::cout << "Success! '" << targetName << "' was found at index " << index << ".\n";
    } else {
        std::cout << "Sorry, '" << targetName << "' was not found in the array.\n";
    }

    return 0;
}
