C Program to Display same Source Code as Output

C Program to Display same Source Code as Output.

⦁ When working with files, we need to declare a pointer of type file. This declaration is needed for communication between the file and program.
                              FILE *fptr;

⦁ Opening a file is performed using the library function in the "stdio.h" header file: fopen( )

⦁ The syntax for opening a file in standard I/O is
                 ptr = fopen("fileopen","mode")

--------------------------------------------------------------------------------------------------------------------------

#include<stdio.h>
int main ( )
{
     FILE *fp;
     char ch;
     fp = fopen(_FILE_,"r");
     do
     {
           ch = getc(fp);
           putchar(ch);
     }
     while(ch ! = EOF);
     fclose(fp);
     return 0;
}
