As seen in the example form Mastery Topics 2. You should only write the function outside the main fucntion and finally, in the main fucntion, write the name of the function while stablishing what are the parameters for it (making sure the type of each parameter is the adequate for the function. remember that int and doubles can be easily converted, but char cannot become an int or a double and viceversa).

Similar to the output, what changes is that, instead of cout and what followed according to the mastery topics-, you type cin(comes in) and two arrows rightwards (>>) and store the text in a variable (you should determine wheter as an int, double or char variable, be sure to revise Mastery Topics – 3).

As easy as it may see, after importing the library and use namespace std, to give an output you only have to write an int main() and follow between the braquets a cout (comes out), two arrows towards the left (<<), the text within quoting marks and following yet another two arrows with endl or \n, both are correct as long as you end with a semicolon.

A type determines what the variable is and what can contain.
Baisc types are int, double and char.
Char is for variables with text, however, you have to denotate the number of characters for it, as if you print a Char=”Hola”, it will only print the first letter.
Int is for integer numbers and double for float numbers. If you declare an int variable’s value as a float number (ex: int x=2.4), decimals will be chopped out; similarly, when you give a double variable’s value an integer number, a decimal space is added to it (ex: double x=1, will be interpreted as 1.0)

To have a proper coding style you have to optimize the space of the text of the code, use comments, remove innecesary codes (or make them shorter).
A simple example is the code I used for the WSQ05, which, looking at it again, sucks on space optimization.
This way is how it should be coded
Use of comments to describe what thing does that part of the code does, remove spaces that are not necessary, yet leaving those that may distinguish which part of the code are similar to others. (inputs and outputs, functions)

A comment is a piece of text in a cod that is meant to be readed for humans, not programs. Their main use is to facilitate the programmer to understand the code.
#include <iostream>
using namespace std;
int main()
{
cout<<“Hi”<<endl;//This is a comment
cout<<“Hellow world”<<endl; /*which can be used to say that
this will print out
“Hello world”*/
}
