[mszp]

1. What is a function?

It is resuable sequence of statements designed to do particular job.

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

The first function is the main one.

3. What are return values?

These values are returned to the caller functions.

4. Are nested functions allowed in C++?

No, they are not allowed.

[zoidsoft]

1. What is a function?

A sequence of reusable code with a return value.

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

int main()

3. What are return values?

This is the result of a function which can return boolean, integers, objects (instantiated classes), etc.

4. Are nested functions allowed in C++?

No, but they are allowed in Pascal. I’ve never really used this much in Pascal but the idea of doing something like this is to reduce the scope of the function to the current procedure or function.

[Howard]

What is a function?
A function is a block of code that contains a group of statements that instructs the CPU to do a specific job.

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

What are return values?
A return value is a Value returned by a function.

Are nested functions allowed in C++?
A nested function is not allowed with C++.

[andersbraath1]

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

2. The main() function.

3. Data that is sent to the caller from a given function.

4. No, a function can not be defined in another function.

[hutch]

1. What is a function?
   A function is a module that contain a sequential set of statements that do a particular job and are reusable.

2. What function is run first of all in a C++ program?
   All programs run the ‘main’ function first.

3. What are return values?
   These are values that are returned by the called function to the caller.

4. Are nested functions allowed in C++?
   No. All functions have to be separately defined.

[Fairway]

1. A function is a reusable sequence of statements designed to do a particular job.
2. The function named main (which is where the program starts execution when it is run)
3. A return value of a certain type is given back to the caller.
4. No.

[PWNSAUCE]

What is a function?

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

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

main

What are return values?

“The specific value returned from a function is called the return value .”

Are nested functions allowed in C++?

no

[iris]

[Dragvandil]

1. A function is a sequence of statements that do a job.
2. The main function always runs first.
3. They are specific values that are given by a function.
4. They are not allowed. Functions can be called inside of functions but they cannot be defined inside the function. They must be previously defined outside of the function.

[pedromndias]

1. What is a function?
   Function is a sequence of statements that can be reused. It provides a way for us to split our programs into small, modular chunks that are easier to organize, test and use.

2. What function is run first of all in a C++ program?
   The main() function is where the program starts execution when it is run.

3. What are return values?
   A return value is a the specific value returned from a function. We have to specify which type of value before the name of the function.

4. Are nested functions allowed in C++?
   In C++, functions can not be defined inside other functions (nested functions not allowed).

[Daniel_Fuchs]

1. sequence of statements determinded for a specific output
2. main()
3. a value which a function creates an return to the calling statement
4. no

[Gedas]

1. Function is a reusable sequence of statements.
2. main()
3. Value returned from a function to a caller.
4. No.

[illyushin]

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

The main function

If you produce a value in a function and want to continue using it outside of the functino, you have to write “return (and name of the value)” this is called the return value

Nested functions are not allowed.

[Ray]

1 A function is a reusable sequence of statements designed to do a particular job.
2 Main function.
3 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 the name of the function when you declare her.
Ex: int myFunction() { return 0; } //return an Int.
4 Nested functions are not supported.

[cryptokaritz]

1. A function is a reusable sequence of statements that perform a specific job.
2. int main()
3. Return values are values that are returned by a called function to the caller.
4. No, a function must be defined above the main() function.

[cherrybluemoon]

What is a function? A function is a reusable sequence of statements designed to do a particular job.
What function is run first of all in a C++ program? Main, which is where the program starts execution when it is run.
What are return values? First, your function has to indicate what type of value will be returned.
Return type, which is the type that is defined before the function’s name.
Second, inside the function that will return a value, we use a return statement to indicate the specific value being returned to the caller. 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.
Are nested functions allowed in C++? No, in C++, functions cannot be defined inside other functions.

[Adam]

1 A reusable sequence of statements designed to do a particular job
2 main()
3 The values returned when a function is called
4 no

[paschkka86]

1. What is a function?
   A function us a reusable sequence of statements designed to do a particular job.
   -> way to split the program, modular chunks which are easier to test and use

  }

3. What are return values?
   Data from a function, which is provided to the caller
