    Can repeated characters be printed with a C statement?

    'Basic' had a way to choose a character and repeat it as many times as needed in one statement. Great for drawing horiziontal lines in text-mode applications. Does such a statement exist in C of should I just use a FOR/LOOP? (No need to post a FOR/LOOP code, I can do that, I'm just looking for a shortcut if it exists by using some form of printf, puts, etc. statement if ones available.)

    Thanks,

    Pete

    In C? Not that I know of using just a single statement. You can do it in C++ by outputting a temp string object initialized to an arbitrary number of a specific character though.

    Write a function.
    Code:
    void putcn( int c, size_t n )
    {
        size_t x;
        for( x = 0; x < n; x++ )
            putc( c );
    }

    Hope is the first step on the road to disappointment.

    An odd thing to do:
    Code:
    #include <stdio.h>
    
    void foo(int count)
    {
       static const char ch[] = "*************************************************";
       printf("%.*s\n", count, ch);
    }
    
    int main()
    {
       foo(5);
       foo(10);
       return 0;
    }
    
    /* my output
    *****
    **********
    */

    Thank you everyone,

    I did not think I missed anything. I spent about an hour reading over various C statements and tutorials before I asked.

    I am working strictly in C to avoid getting too confused but thanks hk_ for the C++ info.

    quzah - The FOR/LOOP I know, but I did mine with printf. Thank you for posting it another way with put. Examples alway help a lot.

    Dave - Good idea, glad I thought of it (well, after I saw your post!) Sure, that would work great for the times when you have text characters that form lines and borders. Thanks for showing me how to control the size of the output. Very much appreciated.

    Wow, I'll say it again, what a great forum community you have here. I also need to apologize. I left my computer on today when I left to attend to some other things. I didn't shut down the browser windows, so it may have read as if I was on. Sorry about that. I would have responded sooner had I been able to but I think you will find I will be the type to always respond to a reply...well, unless it's ancient.

    Thanks again,

    Pete
