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:Here is the main discussion of

VariableGlobal variables:1 . Variables placed outside of all functions int N; 2 after the program starts, the main function is created and destroyed after the main function is finished. In a multi-file structure program, the global variable should

Overloading, overwriting, and hidingCommon denominator: Function names are the same.(1) Overloading: must be within a domain, function names are the same but function parameters are different. The effect of overloading is that the same function

The C language provides several standard library functions that convert numbers of any type (integer, long, float, and so on) to a string. The following is an example of converting an integer to a string using the Itoa () function:# include #
