Functions in C++ - Reading Assignment

C++ Programming
#323

  1. In C++, a function is a reusable sequence of statements designated to a particular task.

  2. The first function to run in a C++ program is main()

  3. Return values are returned from function calls. Function return values provide a way to return a single value back to the caller. When the return statement within a function is executed, the return value is copied from the function back to the caller.

  4. No. Nested functions are not allowed in C++

1.) A function is a reusable sequence of statements designed to do a job. They allow us to group our program into small bite size chunks in order to make them easily managed.
2.) The Main function is the first ran in all C++ progams. This is where the program starts execution when it is run.
3.) The return value is a way for functions to return any single value back to the functions caller.
4.) No, c++ does not allow for nested functions.

  1. What is a function?
    A function is a reusable sequence of statements designed to do a particular job. The statements in the function will execute sequentially.

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

  3. What are return values?
    They are the specific value returned from a function. A return value is returned to the function caller by way of a return statement. The return value will be of a specific type which is determined by the type before the functions name eg int numberOfLives() where int is the return type and numberOfLives is the function name.

  4. Are nested functions allowed in C++?
    No, nested functions are not supported or allowed in C++

QUIZ TIME

1 a function is a reusable sequence of statements designed to do a particular job.
2 main()
3 return values output by a function and you have to specify the type of the value. Example int test () {return 0;} // return is an integer.
4 functions cannot be defined inside of the other functions in C++

  1. What is a function?
    A resusable sequence of statements designed to perform a specific job

  2. What function is run first of all in a C++ program?
    The function defined as the “main” function

  3. What are return values?
    A value that is retunred from the function to the caller

  4. Are nested functions allowed in C++?
    No because functions can not be defined inside another function.

  1. A function is a reusable sequence of statements designed to execute a specific task.

  2. In C++ program, the function int main() is always run first.

  3. Return values are results of a executed function. These results are produced at the end of the function and are sent back to the caller function.

  4. Nested functions are not allowed in C++.

A function is a reusable block of code.

main() is always the first function to run.

The value you want the function to return after it is finished.

No.

1 A function is in it self a program, a sequence of statements (instructions).
2 main()
3 The return value is what the function generates (due to the input).
4 No, all definitions of functions must be “outside” any other function.

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? The main function is the point by where all C++ programs start their execution, independently of its location within the source code.
3. What are return values? What are return values? Return values are just what they sound like — the values that a function returns when it has completed.
4. Are nested functions allowed in C++? Nested functions are supported as an extension in GNU C, but are not supported by GNU C++.

What is a function?

Functions are commands groups that executes lines abstracted by algorithms and are operating units in the language. 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. *

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

main()

What are return values?

Output values from a function call.

Are nested functions allowed in C++?

No, nested functions are not supported in C++.

Q.)What is a function?
A.)A function is a block of code which only runs when it is called. You can pass data, known as parameters, into a function. Functions are used to perform certain actions, and they are important for reusing code: Define the code once, and use it many times.
Q.)What function is run first of all in a C++ program?
A.) The execution of all C++ programs begins with the main function, regardless of where the function is actually located within the code.
Q.)What are return values?
A.) 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.
Q.)Are nested functions allowed in C++?
A.)In short NO, Not supported by GNU C++. Nested function definitions are only permitted within functions in the places where variable definitions are allowed; that is, in any block, mixed with the other declarations and statements in the block.
