    Normally, If you would like to print to standard output you can go ahead with Printf, In case if you want to Print any thing to user defined Files, you can use fprintf.
    There is not much difference between printf and fprintf, if your writing to standard output

    Thanx,

    Gobinath is right. Irrelevant to the question however, this is the prototype for fprintf()
    Code:
    int fprintf(FILE *stream, const char *format, ...);
    so im not sure why you put a 5 here
    Code:
    fprintf(stdout,"asdfa",5);

    fprintf(stdout, "blah");

    is exactly the same as

    printf("blah");
    If you understand what you're doing, you're not learning anything.

    Think of printf() as a "wrapper" for fprintf(stdout....)
