Built-in types (int, char, double etc) are not defined in headers, because they are built-in types.
Header files contain data-definitions and function-prototypes (those may include compiler-specific informations, like __attribute__), but not function implementations. If you are interested in the source code of library functions like printf, you have to do some Google search.
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);
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

Turbo C++ keywords are the same as C++ keywords. The language remains the same, only the implementations differ. The Turbo C++ implementations were standards-compliant at the time of their release, but the product is no longer supported.

Predefined functions are functions that have been written and we can use them in our C++ statements. But we must know how to use each of these predefined functions.
I guess you mean predefined functions or library functions. Well, you don't have to use them, but they can be useful.

yes
it is predefined function
32 keywords are present in C language. There are 44 keywords in C99.
Predefined functions in C are those that are part of the C library. These are present in any of the various headers that can be included in a program. For example, the function double sqrt(double) present in <math.h> that computes the square root of the argument passed to it.
