Functions in C++ - Reading Assignment


#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

#62

What is a function?

  • a set of instruction we would like to reuse for a particular task
    What function is run first of all in a C++ program?
  • main()
    What are return values?
  • a value with type declared when the function started, and will be returned when the function finished
    Are nested functions allowed in C++?
  • no

#63
  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.

#64
  • 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++.

#65
  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.

#66

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?
function main()

3.What are return values?
return values are specific value being returned to the caller.

4.Are nested functions allowed in C++?
NO!


#67
  1. A function is a reusable sequence of statements designed to do a particular job.

  2. The main function gets executed first.

  3. Return values are outputs from a function

  4. No functions cannot be defined inside other functions, but a you can call a function inside another function that was previously defined.


#68

What is a function? it 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? the actual value returned from the function;

Are nested functions allowed in C++? no


#69

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.


#70
  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.

#71
  1. A function is a group of statements that together perform a task.

  2. int main()

  3. Data that is sent to the user who called a given function

  4. No.


#72
  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


#73

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.


#74

What is a function?

  • a reusable sequence of code statements designed to execute a specific “function” or task.

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

  • int main()

What are return values?

  • output values returned from the function

Are nested functions allowed in C++?

  • no, not allowed

#75
  1. a reuseable block of code that performs a series of actions.
  2. the function called main
  3. what the function passes back to the caller
  4. no

#76

Functions in C++ Reading Assingment

1. A function is a reusable sequence of code that can return a value. 2. C++ runs main() first in any program. 3. a function can only return 1 value or no value (void). 4. Nested functions are not allowed.

#77

What is 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++


#78

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 Function.

What Are return values?

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++ ?

Nope


#79
