I´m going to explain you the #mastery19, which is the do, while mastery. When you want to do a loop with do while there is one thing you have to understand, ther will be one condition and the program will work until that condition is true. Because sometimes people think the other way around, they think that the program have to work until the condition be false and that´s not right.

Knowing this let´s get started.

First you have to put the word “do” and open keys “{}”, inside the keys you will put whatever program you want and at the end after the key you have to put “while” and between parenthesis you have to put the condition you want the program to work until it is true.

After the while you can put an output message or continue with your program.

Here is an example, enjoy!

Here i will show you how to put libraries in c++, which is #mastery13.

Is really simple you just have to put at the beginning of the code hashtag “include” and between this <> the name of the library. Like this “#include <(name of the library)>” and that´s it.

Here is an example.

Enjoy!

This is a post where i will show you  the #Mastery10 which is how to put a basic output and input.

To do an output you just put “cout<< (Whatever you want to print between quotes) (if you want to print a variable put the variable between this “<<” and then put a semi colon “;”.

To do an input you will have to declare a variable, lets say the variable is called “num”, once you have your variable you do this “cin>> num;” and that´s all now you saved whatever you asked the user to give.

Here is an example to make it easier

Enjoy!
