1 - A function is a set of statements that execute whenever the function is called

2 - The main function runs first in C++

3 - Functions either return a value when called or are void. Return values are identified with the “return” statement

4 - Nested functions are not allowed in C++

1- A function is a reusable sequence of statements designed to do a particular job.

2- int main()

3- Return values are the output values that are returned back to the user as a conclusion of a function.

4- Unlike some other programming languages, in C++, functions cannot be defined inside other functions.

  1. A function - is reusable sequence of statements design to do a particular job.

  2. the int main () is the first function that is run

  3. The specific value returned from a function is called the return value. When the return statement is executed, the return value is copied from the function back to the caller. This process is called return by value.

  4. Nested functions are not allowed in C++

  1. “A reusable sequence of statements designed to do a particular job.”
  2. Main
  3. “A specific value returned from a function.” This can be easily used to return for example a result of a functions, that calculated something, that we have to use in another function.
  4. Nested functions are not supported.

  1. What is a function?

A function is a collection of statements that executes sequentially and a function may be used multiple times within the scope of a program.

  1. What function is run first of all in a C++ program?

The main function runs first.

  1. What are return values?

Any function in C++ that is not of the type void can have a return value. The data type of the return value is determined at the point of the function’s definition. The return value of a function may be passed on to the main function and be used there.

  1. Are nested functions allowed in C++?

No.

  1. a function is a reusable code containing one or more statements. Every function is written to do a particular job and can be called by other functions, but also call other functions itself.

  2. main function

  3. the returned value of a function after being called and executed.

  4. no

FORUM QUESTIONS

  1. What is a function?
    A function is sequence of statements set out to perform some set of instructions. These instructions may print, compute, store and manipulate data.

  2. What function is run first of all in a C++ program?
    In every C++ program, a main() funtion must be called.
    Everything that is to be executed in the program should go within the body of the main() function. This is where the program starts executing when it is run.

  3. What are return values?
    A return value is one in which is presented to the computer as a result of executing a function. When a return statement is executed, the value is copied from within the function to the caller.
    This specific value that is copied is known as the return value.

  4. Are nested functions allowed in C++?
    Unlike several other programming languages, C++ does not accept nested functions. You can perform similar tasks as nesting functions, however each function needs to be initialised and defined separately.
    You can however, include functions inside a function; so long as it has been defined separately.

ARTICLE QUESTIONS

  1. In a function definition, what are the curly braces and statements in-between called?
    The part of a function inclusive of the curly braces and contents inside them are known as the body of the function. This is the part of the function which gets executed.

  2. What does the following program print? Do not compile this program, just trace the code yourself.
    The source code published on the article prints:

Starting main()
In doA()
In doB()
In doB()
Ending main()

1. What is a function?
A function is a grouped set of statements that execute when the function is called.

2. What function is run first of all in a C++ program?
The starting point of execution for ALL C++ programs is through the execution of the main function.

3. What are return values?
Return values are the value(s) returned by the function after it is done performing its intended task.

4. Are nested functions allowed in C++?
No. Nested functions are not allowed in C++ as they are in JavaScript.
