I think I did exactly like he showed. But there comes an error message.

When running it through help50 make meow it says:

You seem to be passing in too many arguments to a function on line 8 of meow.c. The function meow is supposed to take 0 argument(s), but you're passing it 1. Try providing 1 fewer argument(s) to the function.

This is my code, please help me to see what I´ve done wrong.

#include <stdio.h>

void meow(void);

int main(void)

void meow(int n)
    for(int i = 0; i < n; i++)

  • Welcome! Three backticks\backquotes\grave accents (`) in a row, followed by the the language (so just typing c for this question) will start a code block with syntax hightlights. If you want to end the code block to type more text, you can close it with three more backticks\backquotes\grave accents, but that is not necessary in situations like this where the code block is the end of the post.

1 Answer 1


The prototype and the actual function don't match.

void meow(void);

void meow(int n)

I'm surprised it even compiled. Both need to have int n
