The default is to use vectors. --alex StepanovThe most useful vector in the C + + standard library is vectors. A vector provides a series of elements of a specified type. You can find an element by its index (subscript), use push_back () to extend

The C language has the following rounding methods:1, the direct assignment to the integer variable. Such as:int i = 2.5; or i = (int) 2.5;This method uses the rounding up of the decimal part 2, the integer division operator in C + +"/"has a

In the view of C + + programming ideas, each exercise is basically using ofstream,ifstream,fstream, before a rough knowledge of its usage and meaning, after reading a few Daniel's blog post, to organize and summarize:C + + supports the input and
