By function We Means In C which Perform Some Specific Task..e.g Print Scan etc.
The function Should Inclosed of Parantheses.
There Are two Types Of Function
1.User Define Function
2.Built in function
A function statement is a block where the function is declared and defined.
Yes. So long as the function has a value at the points in question, the function is considered defined.
You cannot because the function is not well-defined. There is no equality symbol, the function In(2x) is not defined.
A piecewise defined function is a function which is defined symbolically using two or more formulas
A function statement is a block where the function is declared and defined.
That depends on how the function is defined.
The set of all values of x, for which the equation is true is the domain of the function defined by that equation.
A function is not deigned in to another function. It is because that would lead to dependency injection.
No the two work together REALLY
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.
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.
If a subset is defined by enumeration, you could remove "duplicate" entries. If defined by some generating function you might be able to simplify the function.
