Write a C program which produces its own source code as its output

#include<stdio.h>
int main(){
    FILE *fp;
    char c;

    fp = fopen(__FILE__,"r");
    do{
         c= getc(fp);
         putchar(c);
    }
    while(c!=EOF);
    fclose(fp);
    return 0;
}

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