#61
  1. It is a reusable piece of code, instructions, that will be executed every time this function is called
  2. The main() function
  3. These are values that come out of the function after executing all the code inside the function, and we can work further with these return values
  4. No, they are not allowed, all functions must be initialised outside of main(( function

  1. Functions are sequences of code that are stored at a particular memory address with a given name. Other functions can call this address to execute its statements by using its name followed by parentheses.

  2. The main function is the first function to be executed in a C++ program.

3, Return values tell the compiler what kind of value to return to the caller from a given function.

  1. Nested functions are not allowed in C++ and will not compile if included in your code.

  • 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 named main() is run first which is where the program starts execution).
  • What are return values?
    The actual value returned from a function to its caller is called the return value.
  • Are nested functions allowed in C++?
    Functions can not be defined inside other functions in C++.

  1. Function is a block of code meant to be run multiple times. A function call runs that code.
  2. Function named main.
  3. Return values are values returned by function when it finishes executing (function gets to a return statement).
  4. Nested functions are not allowed.

1.What is a function?
A function in C++ is a piece of code that we can reuse (much like in JavaScript). When called, it will execute a set number of steps, that might or might not return a value. After which, the program continues to run.

2.What function is run first of all in a C++ program?
The first function to run would be

int main(){ }
which is the main function when we first start a new project.

3.What are return values?
Return values are values that outputted by the function after it has been called and successfully executed.

4.Are nested functions allowed in C++?
No nested functions are not allowed in C++. One can declare new functions and call them within other functions, but is unable to declare them within another function.

  1. Function is reusable piece of code, constructed for particular task. It contains sequence of statements. Every program in C++ must have function
  2. The main() function
  3. It is value returned by calling the function, the type of return function is defined in front of the function name.
  4. The nested function are not allowed, they would return error.

  1. What is a function?
    A reusable sequence of statements that serves a particular job

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

  3. What are return values?
    Before a function finishes it can return a value to be used outside of that function, this can be a variable, an integer, or anything that holds a value

  4. Are nested functions allowed in C++?
    You can call a function in a function but not define a function in a function

What is a function? A function is a reusable sequences of statements to perform a specific job.

What function is run first of all in a C++ program? A cpp compiler always looks for the main function in a c++ program and would execute this function with all the code included in the function. This could also include functions defined outside or in other files than the main function, but it has to be referred to in the main function to be executed.

What are return values?
Return values are values that the function would return to the computer after executing the code in the function. The type of the return is given by the definition of the functions type name. If you don’t want the function to return any value you can define the function with void instead of example int, double or string.

Are nested functions allowed in C++? Functions are not allowed to be defined inside of other functions in C++(nested functions). Functions has to be defined outside of other functions and thereafter it could be used in other functions as a function.

A function is a reusable sequence of statements that perform a specific task.

What function is run first of all in a C++ program?
That will be the main function, which is where the program will start its execution.

What are return values?
Return values are the values returned by a function to the caller. They are defined by the return type, which is declared before the function name.

Are nested functions allowed in C++?
No, nested functions, which are functions that are defined inside of another function, are not allowed in C++
