Crypt function on Linux

I want to use the crypt function in a program that I am making. I seem to be having troubles using it. Can someone point me in the right direction? (I have read the man crypt)

Thanks in advance. :confused:

Are you calling the external program properly?

Give us an example of the code you are using, so we can see what is going on.

#include <iostream>
#include <unistd.h>

test.cpp
-------------------
void main() {
char *salt="a9";
char *key="Secret";

cout << crypt(key, salt)) << endl;
exit(0);
}

]$ g++ -o test test.cpp

I was missing this: g++ -o test test.cpp -lcrypt. It works now :-) Thanks for your help.
