The C++ standard library contains all the pre-defined functions.
Predefined functions are built-in functions that perform standard operations and that generally do not depend on any classes. A predefined void function is simply a predefined function that has no return value. An example of a predefined void function is the abort() function which typically has the following signature: void abort(void);
it is predefined function
yes
Not necessary, there is a predefined 'pow' function.
No predefined 'header' function in the standard C libraries. There are header files, if that's what you mean.
There is no such term as "building function" in C++.
Guess you meant: can a recursive function call predefined functions? Answer: sure, why not.
Just as you would do it manually, I mean there is no predefined 'solve_equation' function in C.
Predefined codes or the predefined functions are the codes small or large codes which are predefined by the maker of the language. In C++ the predefined codes can be included in the program by the header files. These codes are placed in files and functions could be used to access them. Like a simple console Code to output "Hello World" uses a predefined code cout
That won't happen, you have to have a predefined putpixel (or something like that) function.
I guess you mean predefined functions or library functions. Well, you don't have to use them, but they can be useful.
...a function call.
