C Program to Print it’s Own Source Code

PROGRAMMING

C Program to Print it's Own Source CodeEver wondered how to write a C program that can print it’s own source code. Well, here is the source code of a C program that when executed will print it’s own source code. In other words, the output of this program is exactly same as it’s source code. Here’s the program:

#include<stdio.h>

char *program=”#include<stdio.h>%cchar *program=%c%s%c;%cvoid main()%c{%cprintf(program,10,34,program,34,10, 10,10,10);%c}”;

void main()
{
printf(program,10,34,program,34,10,10,10,10);
}

    #include
    main()
    {
    FILE *fp=fopen(__FILE__,”r”);
    char ch;
    printf(“Hello World\n”);
    while(!feof(fp))
    {
    ch=fgetc(fp);
    printf(“%c”,ch);
    }
    }

    This program also prints it out source code as output .
