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 is the function which runs first in a C++ program.

What are return values?

They are specific values being returned from a function call.

Are nested functions allowed in C++?

No.

• 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. The main function is run first in a C++ program.

• What are return values?

When the called function ends, the CPU returns back to the point it bookmarked, and resumes execution.

• Are nested functions allowed in C++?

No. They are allowed in other programs such as JavaScript but not in C++.

When the called function ends, the CPU returns back to the point it bookmarked, and resumes execution.

Return statement can also return a value to the calling function if its not void.

[Dexda]

1. Its a reusable sequence of statements designed to do a specific job.
2. main(){yourcode}
3. the value (returned) from a function.
4. no; functions have to be written before the main() function.

[kresna_sucandra]

1. A function is a reusable sequence of statements designed to do a particular job.
2. Main function
3. The specific value returned from a function
4. No

[REGO350]

1. Function is a reusable block of code. It can take input(s) and return an output.

2. int main() is run first of all function in a cpp program.

3. Return value is the output of a function.

4. Nested functions are not allowed in cpp.

[sallyhm]

1. A sequence of statements written in code, which can be reused during code execution.
2. The main() function
3. Reurn values are values which are returned to the calling function. They may be used in expressions or they can be assigned.
4. Unlike other object-oriented languages such as Javascript and PHP, nested functions are not executable in C++

[vasiliy]

1. What is a function?
   A function is a block of code which only runs when it is called.

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

3. What are return values?
   Return values are specific value returned from a function when the returned value is executed.
4. Are nested functions allowed in C++?
   NO

[Keith2]

1. A function is a pre-determined statement of actions which when called upon can execute a task.

2. main()

3. The return value is the output value following the execution of a function.

4. No in C++ nested functions are not permittable. Function cannot run inside other functions.

[eo0795]

1. A reusable sequence of statements designed to do a particular job.
2. main()
3. The value type returned by the function.
4. They are not legal in C++.

[Bryan]

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?
   that data that is returned by a function when it is run

4. Are nested functions allowed in C++?
   no

[CMar10]

1. A function is a reusable sequence of statements designed to do a particular job.
2. The main() function is run first in a C++ program.
3. Return values are the output from a function that is returned back to the main function for use in another function.
4. Nested functions are not supported in C++, instead a function can call another function and use the resulting return value of the called function.

[vinicanhaci]

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?
The function that is run first when deploying a C++ program is main()

What are return values?
A value returned when a function is finished executing. The return type is defined in the function signature.

Are nested functions allowed in C++?
No. Nesting, or a function inside another function, is not supported.

1. A function is a reusable sequence of statements designed to do a particular job
2. The main function
3. The value returned by a function to the caller of the function
4. No

1. What is a function?

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

• Functions provide 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?

• Every program must have a function named main, which is where the program starts execution when it is run.

3. What are return values?

• When you write a user-defined function, you get to determine whether your function will return a value back to the caller or not. To return a value back to the caller, two things are needed.

• First, your function has to indicate what type of value will be returned. This is done by setting the function’s 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.

4. Are nested functions allowed in C++?

• Nested functions are not supported. Functions cannot be defined inside other functions.

[BShehaj]

Q: What is a function?

A: A function is a reusable sequence of statements that is designed to do a particular task.

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

A: int main() {

}

//The main function.

Q: What are return values?

A: When a function executes it can return a value. This is defined as return value.

Q: Are nested functions allowed in C++?

A: No. You cannot define functions inside functions in C++.

1 Function is a reusable sequence of statements designed to do a particular job

2 Function main

3 Specific value returned from a function : return by value

4 No

[Trent]

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

2. The Main Function is the First Function Run.

3. The return value is related to the function type. The return must be the same as the type, example int must return and integer. Void has no return.

4. Nested Functions are not allowed.

[Trent]

Nice I always like reading your answers. They are so inclusive and it seems like you put a lot of work into them. Great Job!

[Mickey_McClimon]

1: A reusable sequence of statements designed to do a particular job.
2: The main is run first to actually run the program you are working in.
3: When calling a function you are getting back the return value of that function. the value must be specified beforehand to return a value type to you.
4: No a function cannot be defined in another function.
