Do not know how to implement this into a script in Unix?
Relevant commands, code, scripts, algorithms:
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 */
#include
#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");
printf("\t================\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

Any idea on how to perform this task?

3. The attempts at a solution (include all code and scripts):
Save it in text and save it power2.c but nothing works.

How did you try to save it to a file? There are many editors for UNIX just as with Windows. Is saving it the problem or running it? You know to compile it next...?
you'd generally type:
cc -o power2 power2.c
and then run it, like so:
./power2
edit: OH, the problem is you need to rewrite this C program into a shell script??
Do you understand the C program already? What do you know about shell? Which shell are you learning (Bash? Korn? "sh"?)
If its a c program, it cant be a shell script...
But as a c source program only it can be saved which is nothing more than a ascii text file for unix and so can be read by any editor such as vi...
If its being copied from windows then you would have to check if it doesnt need to be converted using tools such a ux2dos or unix2dos ...
Then only can you try to compile it... as shown by the 2 posts above
