The integer division should truncate toward zero.Assume that the given expression was always valid.Some Examples:"3+2*2" = 7 "3/2" = 1 "3+5/2" = 5Note:do not use the eval built-in library function.

Today to talk about the implementation of the calculator, the effect is how, take out your mobile phone calculator to see the know, note that we calculate the number of two and then click the equal sign will be the result, click the operator will also produce results,. This is the 1th need to pay attention to, the 2nd need to note that after the results come out and then click on the number will overwrite t

Below is the final version of our calculator.The problem now is that the user can only count once. If someone buys a disposable calculator, then he must be a local tyrants. Our calculator can not be used only for local tyrants, so we should change it to be used repeatedly.You can use loop statements, but what code loops? From user input to printing results this process is repeated, and the code is:enumopt{J
