I started reading a well known book called Programming: principles and practice in c++. But the first program that was included in a book looked like that. Now, there are 2 problems. Line #include "std_lib_facilities.h"
my compiler doesn't recognise as a valid code (I thought you should write include iostream) and down where the code cout is, wasn't there seposed to be a code named using namespace std; for the code cout to be written in short version.
#include "std_lib_facilities.h"
int main()
{
cout << "Hello, World!\n";
return 0;
}
