Hammer & Screwdriver C program into UNIX?

Hello folks!

I need help on this one:

I have this C known program which I need to save it as "power2.c", and create it as a file in my UNIX environment:
/* power2.c -- Print out powers of 2: 1, 2, 4, 8, .. up to 2^N */
#define N 16
int main(void) {
int n; /* The current exponent */
int val = 1; /* The current power of 2 */
printf("\t n \t 2^n\n");
for (n=0; n<=N; n++) {
printf("\t%3d \t %6d\n", n, val);
val = 2*val;
return 0;
/* It prints out :
n 2^n
0 1
1 2
2 4
3 8
4 16
5 32
6 64
7 128
8 256
9 512
10 1024
11 2048
12 4096
13 8196
14 16384
15 32768

Any idea on how to perform this task?
