CS50 Task meow.c custom made function doesn´t work

Question

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>

//Prototype
void meow(void);

int main(void)
{ 
    meow(3);
}

void meow(int n)
{
    for(int i = 0; i < n; i++)
    {
        printf("meow\n");
    }
}

Answer 1

The prototype and the actual function don't match.

//Prototype
void meow(void);
...

void meow(int n)
{...

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