int main(int argc, char *argv[])
{
int z = 0;

cout << *argv[2] << endl;

Like this:
#include <iostream>
int main(int argc, char *argv[])
{
std::string str( argv[2] );
std::cout << str << std::endl;
}

Neither 'cout' nor 'endl' are defined. Did you forget to include
a proper header? BTW, your program has undefined behaviour if
the number of arguments is less than 3.

return z;
}

Drop the asterisk in the output statement.

std::string str( argv[2] );

'std::string' is undefined.

std::cout << str << std::endl;

And why do you need the 'str' anyway? Couldn't you just do

std::cout << argv[2] << std::endl;

?

}

Sorry for my awful spelling in original post.

Many thanks for pointing out that removing the * fixed my problem.

As you probably guessed, tester was written just to post this question
rather than bore you with extra variables from the program where I need
to pass arguments.

There is a trend currently propogating whereby C++ programmers try to make
their programs as inefficient as possible, for sake of appearing to use safe
features. This extends to the use of "vector" when all that was needed was a
simple array.

'std::string' is undefined.

Forgot to
#include <string>
but my program compiled. It is probably included in the iostream (at
least in the library I am using)

You could :)

But you shouldn't rely on that.

Yes, I dont. When reviewing my own code, I always include missing
headers (like in this case), alhtough it compiled well.

But this time, I didnt review this example ;)
