g++ compiler and iostream.h


In trying to write basic programs I get what appears to be erratic
errors when using iostream.h and cmath.h in that it tells me to use
the C++ Standard section 17 but where can I find this standard.Cout and Cin
are not recognised by the compiler but this doesn't always happen.
Greatful for any help.

Thanks

Dave

Try using #include <iostream> rather than iostream.h

The iostream.h library has been depreceted, and replaced with iostream. Functionally they are generally the same, but iostream is now part of the 'std' namespace.

Either g++ no longer supports the deprected iostream.h, or you may be using the two interchangably.

Try:

#include <iostream>

using namespace std; // Without this you would have to use std.cin or std.cout

int main(void)
{
char input[16];
cout << "Enter num: ";
cin >> input;
cout << "\nYou input: " << input;
return 0;
}

g++ does support iostream.h, it will give you a warning about "using antiquated headers", but the programs will compile and run properly.

THANK YOU, Boogle.

I've just got the same trouble. But your example is clear enough.

Cheer !
