Well, how would you define the result of multiplying "milk" with "peanuts"?
"mpielaknuts" or "mmmmmmmiiiiiiilllllllkkkkkkk"?
If you want to convert a string to an integer, use the following:

std::stoi(yourString);    // s to i; string to int

@bugbyte sir ? where should i put that ?

[bugbyte]

where ever you want to calculate with int values in strings. Who should know better than you? Maybe here?

cout << "Gross Income: "<< stoi(pay) * stoi(hours) << '\n';

Maybe I should add, you should validate input before processing it.
