Reading, outputting, and saving file content using file streams [abandon Sina Blog]

I have always felt that the part of the file stream in the book is more ugly than A Dream of Red Mansions. I have never understood this problem for almost two years. Today, we have finally solved a part of the problem. It is indeed a leap in terms of "quality.
/*
I want to write a program to read and output the file content to the display and save the file content to a file named Zhaos. renye file (in Linux, the suffix does not matter ). Start to implement

# Include <iostream. h> 〉

Int main (){
File * FP, * Zhaos:
// Open the file
Fp = fopen ("a.txt", "R "):
If (FP = NULL)
{

Printf ("file open erroe! \ N "); exit (0 );
}
Char C;
While (1)
{
C = fgetc (FP); putc (C, FP );
} Fcloese (FP); fcloese (Zhaos );
Return 0:
