    Default Qtcreator won't calculate correctly

    I have the following console program on qtcreator 4.7.

    Qt Code:
    1. #include <iostream>
    2. #include <cstdlib>
    3. using namespace std;
    4.  
    5. int main()
    6. {
    7. int a;
    8. int b;
    9. int result = a * b;
    10.  
    11. cout<<"Enter a";
    12. cin>>a;
    13.  
    14. cout<<"Enter b";
    15. cin>>b;
    16.  
    17. cout<<"You entered"<<a<<"and you entered"<<b<<"Their product is"<<result<<endl;
    18. cout << "Press any key to exit..." << endl;
    19. system ("pause");
    20. return 0;
    21. }
    To copy to clipboard, switch view to plain text mode 

    When i input 5 and 9,i get You entered5and you entered9Their product is-2009147472

    why am i not getting 45?.

    Hm, that's just a guess, but maybe you should calculate the result after the user has entered the numbers...

    Qt Code:
    1. cout<<"Enter a";
    2. cin>>a;
    3.  
    4. cout<<"Enter b";
    5. cin>>b;
    6.  
    7. int result = a * b;
    To copy to clipboard, switch view to plain text mode

    This question has precisely nothing to do with either Qt or Qt creator.

    For future reference, the language you are writing code in is called C++.
