  1. What is a function?
    a function is a piece of code that can be called at any point during a program and it perform a specific task, the use of functions to structure code is very useful since it helps to reduce complexity and size of the program and makes it easier to read and debug

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

  3. What are return values?
    return values are data that’s returned from a function

  4. Are nested functions allowed in C++?
    nesting of functions is not allowed

  1. What is a function?
    The majority of instructions in a program are statements - these statements are grouped into functions. The statements perform actions that generate (with luck) whatever the program was designed to produce. - The programs produce results by manipulating, changing and writing data - in computing, data is any information that can be moved, processed, or stored by a computer. Programs are collections of instructions that manipulate data to produce a desired result.
    A program can aquire data to work with in many ways - from a file or database, over a network, from the user providing input on a keyboard, or from the programmer putting data directly into the source code of the program.
  2. What function is run first of all in a C++ program?
    int main(){
    return 0; (optional because the compiler will already assume)
    }
  3. What are return values?
  • 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.
  1. Are nested functions allowed in C++?
    No, nay never.

  1. What is a function?

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

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

First function to run in every C++ program is main() function which represents the start of program execution.

  1. What are return values?

Return value is the specific value returned (copied from the function back to the caller) from a function.

  1. Are nested functions allowed in C++?

No, nested functions are not supported in C++

  1. What is a function?
  • A function is a reusable sequence of statements designed to do a particular job
  1. What function is run first of all in a C++ program?
  • The run function is also known as the main function, for that is where the program starts its execution when it is in run
  1. What are return values?
  • Return values are when statements stop an execution and returns to the calling function
  1. Are nested functions allowed in C++?
  • Nested functions are not allowed in C++ because functions cannot be defined in other functions

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

  2. Function int main ().

  3. It’s a value that returned from a function.

  4. No, nested functions in C++ are not allowed. You have to declare functions on the top of the code and just called them inside the main function.

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

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

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 the name of the function when you declare her.
Ex: int myFunction() { return 0; } //return an Int

4. Are nested functions allowed in C++?
Not in C++.

NOTE: Don’t forget to declare your function above the main() function. Otherwise, the main function would not find her.
