some functions

[MC felon]

I heard that the operators for string manipulations have been
overloaded in standard c++.
like for strcmp, we use == and for assignment, we use =. is it true?
also, what are the function equivalents in standard c++ for:
1.) clrscr(); //clear the screen
2.) gotoxy(int x_axis,int y_axis); // go to position in screen at x
axis and y axis

Almost, just the other way round. For "==" _you_ use strcmp
and for assignment ("=") _you_ use strcpy. :>

Trust me -- with C++ strings it is much harder to shoot yourself
in the foot than with C arrays of characters.

also, what are the function equivalents in standard c++ for:
1.) clrscr(); //clear the screen
2.) gotoxy(int x_axis,int y_axis); // go to position in screen at x
axis and y axis

There are none, AFAIR. Usually the platform you run your programs
on gives you a platform-specific means to do it, like "conio.h".
Might as well use them in C++.

The std::string is a versatile class with many member functions and
operator overloads.
Overloading operators with any class is a C++ cornerstone.

[15.20] How can I clear the screen? Is there something like clrscr()?

C++ doesn't rely on a screen to be available at all. If it did it
probably wouldn't be portable. While that might seem like a restriction
to you, its one of its strong points. C++ code doesn't confine itself
to any particular graphical user interface (or platform) although some
cross-platform GUI libraries are available.

Yes, but the really nice thing is the concatenation operator +, I can
concatenate strings together without having to worry about buffer
overflows and stuff like that and with a nice syntax:

std::string str = "Hello";
str += " World!";

You've heard that? It's certianly true, but if you want to become
proficient in C++ you need to be learning more efficiently than just
hearing about the occasional feature. You need a good textbook or two.

This is ideal if you have some programming experience

And this is an excellent reference for the standard library, including
(but by no means limited to) std::string
