Using a library "fstream to solve
"Ifstream is to file read
Ofstream for file is written to the flow of
Fstream flow for file read and write

CodePudding user response:

Can you write a complete code

CodePudding user response:

I don't know you is to realize the file input and output?

Suppose you put the files and programs on the same path (i.e., the same folder), you can like this:

Freopen (" STH. In ", "r", stdin);
Freopen (" STH. Out ", "w", stdout);

Then you read data from STH. In this file read (you can modify the name of your file name), the output data in STH. Out (also can be modified),

This can be achieved is the file input and output,

Pictures I won't, please trust,
