Functions in C++ - Reading Assignment

[Dan_O_Kane]

1. A function is a reusable sequence of statements designed to do a particular job.
2. main()
3. A return value is the value passed back from the function to the caller.
4. Nested functions aren’t allowed will not compile.

[Ouzo69]

1. What is a function?
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?
In a C++ program the function “main” is run first.

3. What are return values?
If a function does some computation it can deliver back a result. Even the main function has a return value, which is usually “0”.

4. Are nested functions allowed in C++?
Nested functions are not allowed in C++. You can call a function from “main”, but the definition of this function has to be outside of “main”.

What is a function?

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

main

2. What are return values?

Information that is returned by a function.

3. Are nested functions allowed in C++?

No

Questions at the end:

1. the curly braces and statements in between are called the function body.
2. Program starts main calls doA and then doB then doB again then ends main.

1. A function is a reusable sequence of statements designed to do a particular job.
2. int main()
3. The specific value returned from a function
4. Nested function are not allowed in C++, functions cannot be defined inside other function – it is not legal.

1. What is a function?

• A sequence of statements designed to do a particular job. As we give this sequence a name, we can later re-use it by calling just the name.

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

• main()

3. What are return values?

• When we define a function, before its name we state what kind of data it will return. At the end of function body we define the return. If we use the function for side effects, we can type return 0;

4. Are nested functions allowed in C++?

• No. What we can do instead is define a function before and then type a call for that function inside another function.

[LTL]

1. A piece of code that does a certain task.
2. The program will run at the top of the Main() function
3. Calls a function and returns a value:
   subtract(10, 9);
   Output =

cout<<subtract(10, 9);
Output = 1

or

int result = subtract(10, 9);
cout<<result;
Output = 1

4.No

[Rafael_Albuquerque]

1. A function is a reusable sequence of statements.

2. main().

3. The results returned to the caller from functions.

4. No.

[Emmerich]

1. What is a function?

A function is a reusable set of instructions/statements that execute sequentially to perform a specific task.

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

main();

3. What are return values?

They are values returned by a function.

Are nested functions allowed in C++?

No.

[Proniss]

1. a collection of statements that execute sequentially

3. The specific value returned from a function
   4.no

What is a function?

A function is a snippet of code that is seperate from the main sequence that may be called (executed) whenever needed.

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

The main function.

What are return values?

A return value is a unit of data a function may return to its caller if needed. For instance a function declared as an int may return an int that will set the r-value of the function call. If the function is declared as a void it won’t return a value.

Are nested functions allowed in C++?

Nested functions are not supported in C++. All functions must be declared sequentially (not inside of other functions).

[Tordek]

1. What is a function?
   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?
   main()
3. What are return values?
   Value that is returned after a function finished executing.
4. Are nested functions allowed in C++?
   No, this is not allowed.

[enrico]

1. What is a function? 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? int main()
3. What are return values? values which are returned from the function
4. Are nested functions allowed in C++? no, any function should be defined outside another function

[MadAussie]

1. What is a function?
   The reusable sequence of statements coded for a specific objective.

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

3. What are return values?
   Return values are what is recalled when you run a return statement that indicates a value in the memory. Return statements start with return.

4. Are nested functions allowed in C++?
   No they are not. And are traditionally not supported by C++ and Other C languages.

[nwenzel0900]

1. What is a function?
   A function is code that can be used whenever that specific function is called.
2. What function is run first of all in a C++ program?
   The function that is run first is main().
3. What are return values?
   Return values are derived from what the function does.
4. Are nested functions allowed in C++?
   No, they have to be outside of main().

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++?

A1: A function is a collection of statements that can be executed to do a particular job. It is run sequentially over and over.

A2: In a C++ program the first function that runs is the Main function.

A3: return values are specific values you set to be returned back to the caller function within user defined functions. There are two requirements for the function to be returned back to the caller.

First there must be a return type set before the function name. e.g; int, Bool,Void, Double are all types of functions and not the return value itself.

Secondly to return a specific value a return statement must be defined with a return value within the function, and the value is sent back to the caller function.

int returnOne() // int is the type of function
{

  return 1; // this is the return statement with a return value of 1

}
A4: No nested are functions are not legal and not supported in C++

[piciu]

1. A function is a reusable sequence of statements designed to do a particular job
2. Main function is the first to run
3. Values returned from the function execution
4. No

[Thomas_VL]

1. What is a function?
A sequence of statements which can be reused

2. What function is run first of all in a C++ program?
The main()

3. What are return values?
When you call a function, she will return you values. When a function returns value, you have to specify the type of this value just before you declare it

4. Are nested functions allowed in C++?
No not in C++
