Just as pointers can point to variables, pointers can also point to functions. Thus you can pass function pointers to functions. In so doing, you can alter the behaviour of the function by having it call dynamically call arbitrary functions rather than just preset functions.
There is no such thing. You probably meant the main function. The main function is the only function that is required as it serves as the entry point of the program.
-define class with necessary data member & member function. -create object of that class. -communication.
Nemo plus iuris
If you meant x + 5 = 4 then the multiplicity is 1.
No.
colinear and non-colinear are terms that are used when describing points in space, not the graph of a function. Maybe what you meant is "Is the function linear?" The answer to that question is no.
Plus 1 is when you miss a player out when passing.
That is not a function, although it does involve the function of addition. A function is something that is done to numbers.
There is no such term as "building function" in C++.
...a function call.
Control is returning to the caller of the function.
yes,we can make function inline
