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); }
