Void function and returning values

[admin]

Reproducing part of Lecture 1 below:

“We can even change our meow function to take in some input, n, and meow n times:

#include <stdio.h>

void meow(int n);

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

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

[/dm_code_snippet]

The void before the meow function means that it doesn’t return a value, and likewise in main we can’t do anything with the result of meow, so we just call it.”

To me, it returns a value, which is “meow\n”. Once meow function called, it is generating an output, which to me returning a value. I know I am perhaps unable to differentiate between calling without value and calling with value. Help appreciated.
