System function (C++)
#1
Here's what I'm trying to do

Allow users to type in a website (eg google.com) and then use the system function to launch net.exe

I have figured out how to launch net but not how to type cast the string

Google has failed me here

It's simple if you're using std:Confusedtring:

Code:
std::string exe = "net.exe ";
std::string webpage = "google.com";
system(exe + webpage);

Expect I'm getting user input, where I have to cast it.
But, let me try your idea first.

If you're getting user input, you might as well use this:

Code:
std::string exe = "net.exe";

system(exe + USER_INPUT_STRING);

C++ strings are different from C strings, which leads to a lot of confusing bugs like that... It's why I switched to Java. Good luck.

You switched to Java just because of the strings? Really? How often do you use strings, anyway?


Anyways, to Roperson, try this:
Code:
std::string exe = "net.exe ";
exe += USER_INPUT;
system(exe.c_str());

Sorry about my previous post.
