Ameer,
Your if stmt:
if(argv[1] == "hello")
is only comparing the pointer values in memory. You need
to use strncmp(3) to do comparison on strings.

Hi all.
Let's say that I have the following c++ code:
#include <iostream>
int main(int argc, char *argv[])
{
if(argv[1]=="hello")
cout <<"Hello World!";
return 0;
}
When I try that, and I type:
./a.out hello
It doesn't give me any output.
Can someone explain how to process args properly?
Thanks,
Ameer
