There are two options to store strings in C++ The rst is the way done in C now called C-strings A C-string is stored as a sequence of chars terminated by the null character (which is denoted ’0’ and has value 0 as an int) The user must ensure that the null terminator remains present

• The main() function is the default function where all C++ programs begin their execution – In this case the main function takes no input arguments and returns an integer value – You can also declare the main function to take arguments which will be filled with the command line options given to the program // my first program in C++

What is the difference between return and void?

is that return is to come or go back (to a place or person) while void is (obsolete) to withdraw, depart. is that return is the act of returning while void is an empty space; a vacuum or void can be . having lost all legal validity. To come or go back (to a place or person).

How to create a function with a return value?

how to make a function with return values. just like: define random between first input and second input if pick random 1 to 2 = 1 then return first input else return first input. then the you can do. move random between 3 5 steps. so it have 2 results. move 3 steps.

Why does recursion still work using a void function?

Recursion will still work if there is a void function too. Every function will do its work and call the next recursive function and when the base condition is met the recursive call stack will start emptying as they have nothing to do now. The call stack will get emptied. Hope you got it !

What is the difference of non void and void function?

Void (NonValue-Returning) functions: Void functions are created and used just like value-returning functions except they do not return a value after the function executes. In lieu of a data type, void functions use the keyword "void." A void function performs a task, and then control returns back to the caller--but, it does not return a value.
