How can i actually make this program go back to the menu when b is pressed? Im new to C++ so any tips for this script is much appreciated. Also is there any better replacement for the continuous "if/ else if"?ThanksCode:#include <iostream> #include <cmath> using namespace std; int main() { int number; double num1; double num2; double num3; char goback; cout << "Type in 1 to use addition\n" << endl << "Type in 2 to use subtraction\n" << endl << "Type in 3 to use division\n" << endl << "Type in 4 to use multiplication\n" << endl << "Type in 5 to find the square root of a number\n" << endl << "Type in 6 to square a number\n" << endl; cin >> number; if ( number == 1 ) { cout << "Please enter your first number\n" << endl; cin >> num1; cout << "Please enter your second number\n" << endl; cin >> num2; num3 = num1 + num2; cout << "The sum of your two numbers is " << num3 << " Press b to go back to the main menu."<< endl; cin >> goback; cin.get(); } else if (number == 2) { cout << "Please enter your first number\n" << endl; cin >> num1; cout << "Please enter your second number\n" << endl; cin >> num2; num3 = num1 - num2; cout << "The difference between your numbers is " << num3 << " Press b to go back to the main menu."<< endl; cin >> goback; cin.get(); } else if (number == 3 ) { cout << "Please enter your first number\n" << endl; cin >> num1; cout << "Please enter your second number\n" << endl; cin >> num2; num3 = num1 / num2; cout << "The quotient of your numbers is " << num3 << " Press b to go back to the main menu."<< endl; cin >> goback; cin.get(); } else if (number == 4 ) { cout << "Please enter your first number\n" << endl; cin >> num1; cout << "Please enter your second number\n" << endl; cin >> num2; num3 = num1 * num2; cout << "The product between your numbers is " << num3 << " Press b to go back to the main menu."<< endl; cin >> goback; cin.get(); } else if (number == 5 ) { cout << "Please enter your number\n" << endl; cin >> num1; num2 = sqrt(num1); cout << "The square root of your number is " << num2 << " Press b to go back to the main menu."<< endl; cin >> goback; cin.get(); } else if (number == 6) { cout << "Please enter your number\n" << endl; cin >> num1; num2 = pow(num1,2.0); cout << "Your number squared is " << num2 << " Press b to go back to the main menu."<< endl; cin >> goback; cin.get(); } else { cout << "Invalid number\n" << " Press b to go back to the main menu." <<endl; cin >> goback; cin.get(); } cin.get(); return 0; }
