    Explanation to a note.

    Hey there,I was reading a note and I came up across a couple of things I'd like to have explained to me.
    My first question is, what is the purpose of the 2 besides the star on line 6 and the bracketed "int n"? Thanks in advance. This is not an assignment,just a note from the internet.

    Code:
    /* A void function with one argument */
    #include <stdio.h>
    
    /* a void function returns nothing */
    void 
    stars2 (int n)
    {
    int i;
    
    /* a loop displaying a star at
    each iteration */
    for (i=1; i<=n; ++i)
    {
    printf ("*");
    }
    /* change line after each series */
    printf ("\n"); 
    }
    
    int
    main (void)
    {
    int a;
    
    a=10;
    
    /* the argument may be a constant, 
    a variable or an expression */
    
    stars2 (20);
    stars2 (a);
    stars2 (a+2);
    
    return (0);
    }

    "stars2" is the function's name, while "int n" is it's argument. Functions in C
