c++ - Simple calculator issues (Not outputting answers) -

-

just started reading c++ book , 1 of practice problems write small calculator takes input 1 of 4 arithmetic operations, 2 arguments operations, , prints out results.

sadly, program works until user inputs arithmetic option. if chose multiplication, id write "multiplication" , stay there , not after. image of problem im having

#include <iostream> #include <string>  using namespace std;  int main(){     // simple calculator program      // declaring 3 variables     float numberone;     float numbertwo;     string operationoption;      // asking user 2 numbers he/she use     cout << "enter first number apply arithmetic operation to: ";     cin >> numberone;     cin.ignore();     cout << "now enter second number: ";     cin >> numbertwo;     cin.ignore();      // using cin input users selection     cout << "enter operation want perform." << endl;     cout << "the options have are: " << endl;     cout << "multiplication, subraction, division , addition: " << endl;     cin >> operationoption;     cin.ignore();     cin.get();     // happens     if ( operationoption == "multiplication" ) {         cout << "the first number multiplied second number is: " << numberone * numbertwo << endl;     } else if ( operationoption == "division" ) {         cout << "the first number divided second number is: " << numberone / numbertwo << endl;     } else if ( operationoption == "subtraction" ) {         cout << "the first number subtracted second number is: " << numberone - numbertwo << endl;     } else if ( operationoption == "addition ") {         cout << "the first number added second number is: " << numberone + numbertwo << endl;     } else {             cout << "you entered invalid option.";     };  }

remove line :

cin.get();

will solve problem
