    write this program and save it as pro.c....run....it will show the program to the consol and write the source code into data.txt file...................

    #include<stdio.h>
    void main()
    {
    FILE *fp,*ft;
    char buff[100];
    fp=fopen("pro.c","r");
    if(fp==NULL)
    {
    printf("ERROR");
    }
    ft=fopen("data.txt","w+");
    if(ft==NULL)
    {
    printf("ERROR");
    }
    while(getc(fp)!=EOF)
    {

    fscanf(fp,"%s",buff);
    printf("%s ",buff);
    fprintf(ft,"%s ",buff);
    }
    }



    This seems to be taking longer than usual.
