Answer #1

While loop has a syntax which is started by a keyword called 'While' and then it is followed by a bracket and inside a bracket, there can be any arithmetic expression or logical expression which will be in turn computed as boolean value either True or False.
Then, there is a block that can have one or multiple statements inside it. If there are multiple statements inside a while loop, then it should initiate and end with '{' and '}' respectively.

Friend, this was a really nice question. If you find my answer helpful, please like it. Thanks.
