A function is not deigned in to another function. It is because that would lead to dependency injection.

Can a C plus plus user defined function return a value?
Absolutely. Indeed, any function (user-defined or built-in) that does not return a value is not really a function, it is simply a procedure.
Suppose an external variable is defined outside of function A and accessed within the function Does it matter whether the external variable is defined before or after the function. Explain?
No the two work together REALLY
Defult function in c language is?
Default functions are pre defined functions.Eg. printf();scanf();getch();clrscr();etc..Actually, no-one uses the term 'default function'. (Let alone 'defult function'.)Another answer: Perhaps it is 'main' what you meant.
To create a user defined sizeof function?
Not possible.
What enables us to use a function that has been declared and defined in source code?
If the function has been declared and defined, then the only remaining issue is scope, i.e. visibility.
Can you define a function inside a function?
No. Functions should be defined separately. So you would not define a function within a function. You can define one function, and while defining another function, you can call the first function from its code.
What is the user defined function section in C language?
There are no 'sections' in C source, you can define functions anywhere, except inside another function or variable/type definition.
What is a function statement?
A function statement is a block where the function is declared and defined.
If a function is equal to zero when x is zero is the function considered defined at that point?
Yes. So long as the function has a value at the points in question, the function is considered defined.
What can you say about the end behavior of the function f(x)- In (2x) plus 4?
You cannot because the function is not well-defined. There is no equality symbol, the function In(2x) is not defined.
Describe the defining characteristics of piecewise functions?
A piecewise defined function is a function which is defined symbolically using two or more formulas
What is functional statement?
A function statement is a block where the function is declared and defined.
What restrictions are there on the range of the function of H(w)?
That depends on how the function is defined.
If a function is defined by an equation explain how to find its domain.?
The set of all values of x, for which the equation is true is the domain of the function defined by that equation.
Can a C plus plus user defined function return a value?
Absolutely. Indeed, any function (user-defined or built-in) that does not return a value is not really a function, it is simply a procedure.
How do you write rule for a function?
You can write them any way you like, as long as the basic definition of "function" is maintained. Basically, this means that the function must be defined uniquely defined for every input.
Suppose an external variable is defined outside of function A and accessed within the function Does it matter whether the external variable is defined before or after the function. Explain?
No the two work together REALLY
