Functions in C++ - Reading Assignment

#121
  1. It is a sequence of statements that can be used repeatedly, sparing us from having to rewrite code chunks everytime.

  2. main()

  3. It is the value that a callee function returns to the caller.

  4. Nope. You have to define them separately, before main(), can’t define them “on the go” inside other functions.

#122
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?

The function named main, which has to have a type int. You write it int main().

3. What are return values?

Return values are the specific values returned from a function. They are returned thanks to a return statement inside the calling function. The called function has the data type defined directly in its name. For example, for a function to return an integer, you use int NAMEOFFUNCTION(). If you use void NAMEOFFUNCTION, void means that no value will be returned.

4. Are nested functions allowed in C++?

No. While you can have functions calling functions in C++, you cannot define a function inside a function in C++.

#123
  1. A function is a reusable sequence of statements designed to do a particular job.
  2. main
    3.Return value are the data which is returned by a function after it was executed.
  3. No
#124
  1. What is a function? A function is a ‘program within a program’ that is activated when a ‘function call’ is included in your program’s code. The CPU will interrupt the current program, go do the function ‘program’ and then return to the original program and resume from there. More specifically, 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 int main() function
  3. What are return values? return values are what are returned to the main function after the execution of the function that was executed due to the function call.
  4. Are nested functions allowed in C++? No, nested functions are not allowed in C++.
#125

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?
main
3. What are return values?
The value which is returned to the calling function when the called function is complete.
4. Are nested functions allowed in C++?
Nested functions are not allowed in C++.

#126
  1. A function is basically a group of statements within a program. They are used to encapsulate specific functionality that ultimately helps with a programs readability, structure, and maintainability.

  2. int main ()

  3. return values are values returned by a function. When a function is called and it has a return value by another function or the main function, the return value will be returned as a result of the call to it.

  4. No, nested functions are not permitted in C++

#127

1- A function is a reusable sequence of statements designed to do a particular job.
2- The first function to run in C++ programs is the function named main.
3- Return values are the values returned when the function is called.
4- Unlike Javascript, C++ does not allow nested functions. If you want to call functions inside a function, these called functions must be define outside the caller function.

#128
  1. A function is a piece of code, a mini-program
  2. The main function
  3. Return values are values that functions return when they are executed
  4. No
#129
  1. A function is set of statements designed to complete a certain task in the program.
  2. The ‘main’ function is the first function run in C++ ‘int main’
  3. A returned value from a called function
  4. No, C++ doesn’t support defining functions within functions.
