/* Useful Maths Calculator Created by Squid I got bored and played with loops. This code isn't efficient, but I wanted to test my loop skills. I also added commentary to make the experience more likeable. Please leave an upvote if you like it. Enjoy! Input: [first line] operation [second line] first number [third line] second number Operation List (no negative values or answers): addition subtraction multiplication division */ #include int answer; // I like functions. They keep things nice and neat void Addition (int numeroUno, int numeroDos) { int increment = 0; // Always put brackest around Math, it makes it way more raedable while (increment < (numeroUno + numeroDos)) { answer = answer + ((numeroUno + numeroDos) / (numeroUno + numeroDos)); // I always get confused between `++x` and `x++`, so I just use `+=` increment += 1; } std::cout << answer; } void Subtraction (int nombreUn, int nombreDeux) { answer = nombreUn + nombreDeux; // okay, I know to use `++i` in for loops, but I still don't know what that does; too risky for me for (int i = 0; i != (nombreUn - nombreDeux); ++i) answer = i; std::cout << answer; } // Fun fact #1 - I'm part Greek void Multiplication (int enas, int dyo) { answer = 0; // My favourite loop Start: if (answer != (enas * dyo)) { answer += 1; goto Start; } else if (answer == enas * dyo) { std::cout << answer; } else { std::cout << "Come on, multiplying by 0?"; } } void Division (int oneFish, int twoFish) // red fish blue fish { int increment = 0; while (increment <= (oneFish / twoFish)) { std::cout << "One fish, two fish, " << increment << "ish, red fish!"; increment += 1; } } int main() { // Fun fact #2 - `using namespace std;` is considered bad practice std::string operation; std::cin >> operation; int firstNumber; std::cin >> firstNumber; int secondNumber; std::cin >> secondNumber; if (operation == "addition") Addition(firstNumber, secondNumber); else if (operation == "subtraction") Subtraction(firstNumber, secondNumber); else if (operation == "multiplication") Multiplication(firstNumber, secondNumber); else if (operation == "division") Division(firstNumber, secondNumber); else std::cout << "Can you read?"; // FUn fact #3 - You don't actually need a `return 0`! C++ does it for you automatically! }

A very talkative and not efficient calculator. But fun!
