Functions in C++ - Reading Assignment


#41
  1. A function is a sequence of code which is executed when a function call is made
  2. main() function is the one which is there in every c++ program
  3. Values returned from the function is called as return values
  4. Nested functions are not permitted in c++

#42

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?
When a function finishes it returns a return value to the function that called it.

Are nested functions allowed in C++?
nope


#43

1. What is a function?
It’s a sequence of statement that can be reused many times in another functions.

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

3. What are return values?
Return value is the value returned by a function and the type of this value is defined just before the function’s name.

4. Are nested functions allowed in C++?
No. They aren’t allow in C++.


#44

What is a function?
You can use it to encapsulate some statements that you want to reuse.
What function is run first of all in a C++ program?
the mail function
What are return values?
You can define a function and give up the returntype (for example int), then the function is expected to return an int value after calling the function.
Are nested functions allowed in C++?
No


#45
  1. A function is a reusable list of instructions

  2. The main function is always run first in C++

  3. return value, is the value that is returned to the main program to be used.

  4. No, functions cannot be nested in C++


#46

1. What is a function?
Function is a piece of code that can be executed in the specified place during the execution of the program. Functions are designed to execute specified logic and make the code more readable.
2. What function is run first of all in a C++ program?
main
3. What are return values?
Return values are values that are returned by the function.
4. Are nested functions allowed in C++?
No


#47
  1. As the text says, a series of statements that are meant to do a job.
  2. main()
  3. The value a function outputs at the end of execution.
  4. Nope :v

#48
  1. A set of statements ( code ) that can be executed by calling the function.
  2. main()
  3. Values that are passed back to the caller function from the called function.
  4. No

#49

What is a function?
reusable sequence of statements
What function is run first of all in a C++ program?
int main()
What are return values?
0 = success
1 = failure
Are nested functions allowed in C++?
nope, and that’s too bad


#50

What is a function?
It is a reusable piece of code, designed to do a specific job.

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

What are return values?
Is the value that a function returns to its caller after it is executed. Its value has to be specified at
the beginning of the function (the return value can be void).

Are nested functions allowed in C++?
No. You have to place functions that are to be used in your
code before the main() function.


#51

A function is a named series of statements that you can reuse to do tasks as many times as desired. The main() function that is executed when you start a C++ program is just one example.

A return value is a value returned by the function being called (callee) to the code that called the function (caller).

Functions are not nested in C++.


#52
  1. A function is a piece of reusable code that once it is established, you can reuse as many times as needed.
  2. The function to run first in all C++ programs is the main function.
  3. A return value is the type value that a function gives back to the caller once it is done executing. For example, the main function returns an integer type, usually 0.
  4. Functions may not be nested inside other functions. Your program will no execute.

#53

What is a function?
sequence of steps that need to be executed
What function is run first of all in a C++ program?
main() //main function
What are return values?
value returned from a function
Are nested functions allowed in C++?
nested functions in c++ are not allowed

quiz:
1a) 16
1b) can’t compile because there is a nested function
1c) works but it doesn’t print anything
1d)
A
B
1e) it doesn’t compile because void function doesn’t return a value (which we need in cout)
1f)
5
5
1g) can’t compile because the function return 5() is not defined properly
1h)
parantheses are missing. if we type:
std::cout << return5() << std::endl; // it returns 5


#54

1. What is a function?

A function is a reusable sequence of statements that are able to perform a particular task.

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

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

3. What are return values?

A return value is the value that once a function has been executed will return a value to the caller. The return value is generally not printed unless it is specified to do by stating “std::cout”

4. Are nested functions allowed in C++?

Nested function are not allowed in C++ and instead suggested to placed separately.


#55

What is a function?
A function is a piece of code that can be reusable at any part of my code. So i do not have to repeat code everytime i need those statments.

What function is run first of all in a C++ program?
the function that runs first when we run our c++ program is main()

What are return values?
a return value is the value that the caller function receive after call the called function.

Are nested functions allowed in C++?
no


#56
  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?
    Every program has a function named main() which is where the program starts execution.
  3. What are return values?
    Inside the called function, a return statement is used to indicate the specific value being returned to the caller. The actual value returned from a function is called the return value.
  4. Are nested functions allowed in C++?
    Functions can not be defined inside other functions (called nesting) in C++.

#57

1. What is a function?

A function is a reusable series of statements designed to do a certain job.

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

Main() is the function run first of all in a C++ program.

3. What are return values?

Return values are the values returned from a function.

4. Are nested functions allowed in C++?

No.


#58

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?
Every program must have a function named main() (which is where the program starts execution).
What are return values?
Then, inside the called function, we use a return statement to indicate the specific value being returned to the caller. The actual value returned from a function is called the return value.
Are nested functions allowed in C++?
Functions can not be defined inside other functions (called nesting) in C++
Quiz
1A 16
1B Nested functions are not allowed, this program will not compile. .
1C This program compiles but does not produce any output. The return values from the functions are not used by main section of the program, and are not used.
1D Output printed of the letter A and then B on a new line
1E This program will not compile
1F 5 is printed twice, 7 is never return
1G will not compile , invalid name
1H Program compiles, but function not called


#59
  1. A function is a sequence of particular statements, which can be called in other functions.
  2. At first the main function runs
  3. Return values are the value which gets returned by a function after execution. The return type is part of the functions definition. The content of the return value is assigned in the function itself.
    4.no

#60
  1. A function is a reusable sequence of code designed to do a specific job.

  2. The main function

  3. It is something that is needed in functions depending on what type of value the function is declared with. The end of a function returns a value that is then used in your main function. If your function is a “void” then you do not need to return a value.

  4. It is not allowed in C++.
