You need to learn C++ first, these questions are all covered in the basics of the language. And you will not learn it by posting questions here.

When answering a question please:

Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

First : you should learn how to add the code tags to your posts so one can see the code displayed properly.

Your question is unclear. Curly braces are used to delineate groups of code such as the extents of a function or a method, the boundaries of a while or for loop, the extents of conditional statements. Following the while statement there is a left curly brace, some lines of code, and a right brace. The code within that pair of braces will execute continuously while the expression in the while statement evaluates to true.

Braces are fundamental to the C++ language. I recommend you take a look at a tutorial: C++ Language Tutorials[^]
