I get error on system line C++

I have a very simple program written in C++, see it here:

#include <iostream>
using namespace std;
int main()
{
cout<<"Simple message"<<endl;
system("msg * test message");
return 0;
}

When I try to compile this script using command: g++ 1.cpp -o test.exe, I get error:

1.cpp: In function 'int main()':
1.cpp:6:29: error: 'system' was not declared in this scope
  system("msg * test message");
                         ^

I checked code, but I can't find the reason of this error, should I change the compiler or is there mistake in in this code?

Solution

  • system() is defined in stdlib.h (or cstdlib for C++).

    #include <cstdlib>
