One or more. (In other words: you cannot write a program without at least one function.)
C ++ is a computer progamming language just like Java, Python and Perl or even its predecessor 'C'.
computer progamming degree
There are 27 possible functions.
You can have #include after Stdio.h ...it has so many built in mathematical functions like CIRCULAR FUNCTIONS, ABSOLUTE VALUE and more..Sadly, built-in functions and library functions are different things... there are no built-in functions in C (except for sizeof, which isn't an actual function).
Attending some universities curriculums, would be "C language". However, currently could be exist better versions like Linus.
Yes, there can be friend functions in C++.
compound c language is complicated where we need to use many nested functions and loops
One.
C++ built-in functions are those functions that are provided for you as part of the language itself, and includes all of the C standard library functions (all of which were inherited from C) and is expanded upon by the C++ standard template library. C++ implementors may provide additional functions that are platform-specific, however these are not considered built-in functions becuase C++ is a cross-platform language. These are best described as 3rd party functions. The functions you yourself write are known as user-defined functions.
C programs do not function without functions.
No, because C does not support the concept of template functions. Template functions only exist in C++, never in C.
Not possible in C, only in C++
