How to run C program on Mac OS X using terminal?

Question

I am new to C. Here is my "Hello world!". Program.

#include <stdio.h>

int main(void)    
{
  printf("Hello, world!\n");
  return 0;
}

After I try to run it using the terminal, it says:

MacBook-Pro-MacBook:~ macbook$ /Users/macbook/Desktop/peng/Untitled1
-bash: /Users/macbook/Desktop/peng/Untitled1: Permission denied
MacBook-Pro-MacBook:~ macbook$ 

Why?
