Read a book, found that C + + and C, although on the hair similar, but the way to solve the problem is not the same, after all, object-oriented and process-oriented are two different ways of thinking. The following is a comparison of C and C + + by

First, decltype meaningSometimes we want to infer the type of the variable you want to define from the type of the expression, but you don't want to initialize the variable with the value of the expression (auto if you want to initialize). To meet

First, process-oriented programmingThe program is mainly composed of a function.There is a close correspondence between the calling procedure of the function and the algorithm's solving steps.Second, object-oriented programmingThe program consists

This is a very basic interview question, but to be considerate.First, reverse a string:The basic idea is to change to a char array, then call the method inside C #, or set two index, traverse from head to tail, and swap.Method One: Array.reverse
