What actions are performed when function is called?

In the context of a macro or program, the values of the arguments of the function (variables) are substituted into the function and it is evaluated. The result is returned.


Does a function that takes a value or values and performs an operation return a result to the caller?

Not necessarily. A function that accepts one or more arguments may process those arguments but need not return any value to the caller. In this case the function simply returns void.


What are the different types of function in c plus plus programming?

There are five types of functions and they are:Functions with no arguments and no return values.Functions with arguments and no return values.Functions with arguments and return values.Functions that return multiple values.Functions with no arguments and return values.Functions with no arguments and no return value.A C function without any arguments means you cannot pass data (values like int, char etc) to the called function. Similarly, function with no return type does not pass back data to the calling function. It is one of the simplest types of function in C. This type of function which does not return any value cannot be used in an expression it can be used only as independent statement.Functions with arguments and no return value.A C function with arguments can perform much better than previous function type. This type of function can accept data from calling function. In other words, you send data to the called function from calling function but you cannot send result data back to the calling function. Rather, it displays the result on the terminal. But we can control the output of function by providing various values as arguments. Functions with arguments and return value.This type of function can send arguments (data) from the calling function to the called function and wait for the result to be returned back from the called function back to the calling function. And this type of function is mostly used in programming world because it can do two way communications; it can accept data as arguments as well as can send back data as return value. The data returned by the function can be used later in our program for further calculations. Functions with no arguments but returns value.We may need a function which does not take any argument but only returns values to the calling function then this type of function is useful. The best example of this type of function is "getchar()" library function which is declared in the header file "stdio.h". We can declare a similar library function of own. Functions that return multiple values.So far, we have learned and seen that in a function, return statement was able to return only single value. That is because; a return statement can return only one value. But if we want to send back more than one value then how we could do this? We have used arguments to send values to the called function, in the same way we can also use arguments to send back information to the calling function. The arguments that are used to send back data are called Output Parameters.It is a bit difficult for novice because this type of function uses pointer


Write a program to return a function using class in C Plus Plus?

Classes cannot return values, only functions can return values. But you cannot return a function from a function, you can only return a function pointer -- a pointer variable holding the address of the function you wish to return. All possible return values must be of the same type, therefore all function signatures and return types must be exactly the same -- only the name of the functions can differ.


Values used with a function in Excel?

Arguments


The values that you use with a function are called?

values used with a function are called


All the values that go into a function. All of the input or independent values what is this called?

They are called the arguments of the function.


What are the values that are used in a function?

There are several possibilities. They can be called arguments and there are two kinds, variables and constants. Variables can have different values and constants are always the same.


The set of all values that a function will return as outputs is called the of the function?

The set of all values that a function will return as outputs is called the *range* of the function.


Design a function named max that accepts two integer values as arguments and returns the value that is greater of the two For example if 7 and 12 are passed as arguments to the function the function?

The function already exists in PHP and is even called max(); Otherwise use: function max ($one, $two) { return $one > $two ? $one : $two; }


Mention the importance of subroutines in programming?

A subroutine is typically defined as being a function or procedure that can be invoked at any point in a program, causing the procedural execution to branch to the subroutine. This is not unlike a goto or jump statement, however subroutines also make use of the program's call stack to allow values (arguments or parameters) to be passed to the subroutine, including the address of the caller so that execution can return to the point of the call when the subroutine falls from scope. A subroutine can also (optionally) return a single value to the caller, known as the return value. Return values are temporary and will fall from scope when the expression that invoked the subroutine falls from scope. However, by assigning a subroutine to a variable, the return value can be stored in that variable and can then used in subsequent expressions. Subroutines pop their arguments from the stack and construct local variables or references from the argument values. Arguments passed by reference can therefore be used to return values through the referenced values. Values returned in this manner are known as output arguments. Subroutines that use output arguments often use the subroutine's temporary return value to indicate any errors that occurred within the subroutine, with zero indicating success (no error).


What should a function include?

A function must include an interface and an implementation. In some programming languages the two may be declared separately, particularly if the language is declarative. The interface typically consists of the function's return type followed by the function name and the type of its arguments, if any, usually enclosed in parenthesis (often round brackets). In untyped languages, the return type and the type of arguments may be optional, but the arguments must be formally named while the return value usually has the same name as the function. In typed languages the types must be specified but the names are optional unless the interface and implementation are combined. In typed languages that support function overloading, the function name and the number and type of the arguments form the function's unambiguous signature. The signature also includes the constness of the function and its arguments where supported, but does not include the return type nor any argument default values that may be provided. The function's implementation must duplicate the interface (if declared separately) but must also formally name the arguments. The function body is usually parenthesised (often in curly braces).
