Geometric calculator in c++

Answer 1

#include <iostream>

int main() {

std::string method;
std::string Options;
double num1, num2;

std::cout << "Welcome to Calculator.\n";
std::cout << "Can I be of any help?\n";
std::cout << "What do you want to do : ";
std::cin >> method;

if (method == "addition") {
std::cout << "Enter First Value : ";
std::cin >> num1;
std::cout << "Enter Second Value : ";
std::cin >> num2;
std::cout << "Answer : ";
std::cout << num1+num2;
}

else if (method == "subtraction") {
std::cout << "Enter First Value : ";
std::cin >> num1;
std::cout << "Enter Second Value : ";
std::cin >> num2;
std::cout << "Answer : ";
std::cout << num1-num2;
}

else if (method == "multiplication") {
std::cout << "Enter First Value : ";
std::cin >> num1;
std::cout << "Enter Second Value : ";
std::cin >> num2;
std::cout << "Answer : ";
std::cout << num1*num2;
}

else if (method == "division") {
std::cout << "Enter First Value : ";
std::cin >> num1;
std::cout << "Enter Second Value : ";
std::cin >> num2;
std::cout << "Answer : ";
std::cout << num1/num2;
}
}
