Functions in C++ - Reading Assignment

[camarosan]

• What is a function?
  A reusable group of statements that works for a special purpose on our programs
• What function is run first of all in a C++ program?
  main function
• What are return values?
  The information that you return to the caller function… For the main function is generally 0
• Are nested functions allowed in C++?
  No

1. What is a function?

• A reusable part of code.

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

main ()

3. What are return values?

The values the caller returns from functions.

4. Are nested functions allowed in C++?
   No. Unlike in other programming languages, nesting functions are not allowed.

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

2. main()

4. Not allowed.

[CaliCrypto22]

1. What is a function?
   A: A function is a reusable sequence of statements designed to do a particular job.

2. What function is run first of all in a C++ program?
   A: Every program must have a function named “main” (which is where the program starts execution when it is run).

3. What are return values?
   A: A value that is created/outputted by a function.

4. Are nested functions allowed in C++?
   A: No, nested functions are not allowed in C++

[PapatoniC]

1. What is a function?
   A function groups a set of actions and processes usually for an specific purpose that can be called on the app at any time, as many times needed, so the code can be reused.

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

   Main function

3. What are return values?
   The values that a function returns after all actions and processes inside the function are finished , so this values can be used afterwards

4. Are nested functions allowed in C++?
   a Function inside another function , which is not supported in C++

• What is a function?
• What function is run first of all in a C++ program?
• What are return values?
• Are nested functions allowed in C++?

• A function is a reusable sequence of statements that are designed to do a particular job. Functions that you create yourself are called user-defined functions.

• The function named main() is run first in all C++ programs, that is where the program starts execution. Most programs use many functions.

• Return values are the specific value returned from a function. We get the return value when the return statement is executed.

• Nested functions are not allowed in C++, as functions cannot be defined within another function. A function can call another function.

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

2. Function named main.

3. Return values are the specific values returned from a function.

4. No they aren’t allowed. Unlike some other programming languages, in C++, functions cannot be defined inside other functions.

[waka]

1. A function is a reusable sequence of statements designed to do a particular job.
2. main()
3. Return values are the address where a C++ function returns after it has executed all its statements.
4. No, they are not. They have to be written in separate blocks.

[kryptoslav]

1. collection of statements
2. main
3. data sent to caller from called function
4. nope!

[SabineB]

1. What is a function?

A function is a reusable sequence of statements designed to do a particular job. Every program must have a function named Main.

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

The first is always run the function Main

3. What are return values?

When a user-defined function is written, you also need to define the return value, which program will return after the function is called and executed.

4. Are nested functions allowed in C++?

No

Welcome to the discussion about the reading assignment about Functions in C++.

Leave your answers to the questions below in this thread. If you have any questions or you want to discuss something connected to the assignment feel free to do it in this thread as well, but please everything to the topic.

1. What is a function?
2. What function is run first of all in a C++ program?
3. What are return values?
4. Are nested functions allowed in C++?

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

2. Function named main

3. Values return back to the caller using return statement.

4. No.

[Louiseee618]

1. What is a function?

It is a reusable sequence of statements designed to do a particular job.

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

Function main is a must because this is where the program starts execution when it runs.

3. What are return values?

It is the specific value returned from a function.

4. Are nested functions allowed in C++?

Nested Functions are not supported. C++ functions cannot be defined inside other functions. It is illegal.

[porter]

1. Re-usable sequence of statements designed to do particular jobs.
2. A function named main.
3. It is the return type of a user-defined function.
4. No. Nested functions are not supported, because they cannot be defined in side other functions.
