Resolving "'hi' is not recognized as internal or external command..." error using C++ with codeblocks on Windows Vista?

Question

I am learning C++ in school now. Currently using C++ with codeblocks on my windows vista laptop. I noticed whenever I try to use functions from imported classes from the Clibrary I get an error in the console.

" 'hi' is not recgonized as internal or external command, operable command or batch file "

My code looks like this ...

#include <iostream>
#include <cstdlib>  

using namespace std;

int main()
{
    system("hi");
    return 0;
}

Just something simple you can see, however I am getting that error. I can use the iostream fine, I have tested the io include and that works... is there something else I need to install to be able to use the cstdlib?

Thank you, Zach Smith

Answer 1

The error is exactly what it looks like: you're trying to execute with system a command that simply does not exist, so you'll get just the same error if you typed hi at a command prompt (codeblocks has nothing to do with it). Try using e.g. system("echo hi") or any other command that does exist and your results might be better.

Answer 2

system() in cstdlib runs another command on the system. Unless there's a hi.exe on your path, this is going to fail. It looks as if you want to write "hi" to stdout, in which case your code should be:

#include <iostream>

using namespace std;

int main()
{
   cout << "hi" << endl;
   return 0;
}

Answer 3

If you want to use iostream, try:

cout << "hi" << endl;
