Question

What is the best way to describe this program with instructions written above each function so that other programmers understand the program for this simple C++ program?

#include <iostream>

#include <fstream>

#include <string>

#include <limits>

using namespace std;

string mixColors(int color1, int color2) {

string mixedColor;

if ((color1 == 0 && color2 == 1) || (color1 == 1 && color2 == 0)) {

mixedColor = "purple";

} else if ((color1 == 0 && color2 == 2) || (color1 == 2 && color2 == 0)) {

mixedColor = "orange";

} else if ((color1 == 1 && color2 == 2) || (color1 == 2 && color2 == 1)) {

mixedColor = "green";

} else {

mixedColor = "No Mix";

}

return mixedColor;

}

int getUserInput() {

int color;

cout << "Enter a prime color: " << endl;

cout << "'0' for red, '1' for blue', and '2' for yellow: ";

while (!(cin >> color) || color < 0 || color > 2) {

cout << "Invalid input! Please enter a valid color ('0', '1', or '2'): ";

cin.clear();

cin.ignore(numeric_limits<streamsize>::max(), '\n');

}

return color;

}

int main() {

string arr[] = {"red", "blue", "yellow"};

int color1, color2;

string mixedColor;

char choice;

ofstream outputFile("color_mixer_results.txt"); // opens file that truncates

do {

color1 = getUserInput();

color2 = getUserInput();

mixedColor = mixColors(color1, color2);

// below is where input inside do while loop is writ to .txt file

outputFile << "Mixed color for your selection (" << color1 << " and " << color2 << ") is " << mixedColor << endl;

cout << "Mixed color for your selection (" << color1 << " and " << color2 << ") is " << mixedColor << endl;

cout << "Would you like to mix again? (Y/N): ";

cin >> choice;

} while (toupper(choice) == 'Y');

outputFile.close(); // closing output file

cout << "Results have been saved in 'color_mix_results.txt'. Goodbye!" << endl;

return 0;

}
