Day 2 of 30-Day .NET Challenge: Variable Scope & Logic Control with Code Blocks

Introduction

Code blocks in programming are essential for grouping code lines and controlling variable accessibility. Variable scope, which determines where a variable can be accessed, is influenced by code blocks.

Learning Objectives:

• Gain insight into the implications of declaring and initializing variables within and outside code blocks.

Prerequisites for Developers

• Declaring and initializing variables.
• Utilizing if-else selection statements.
• Employing foreach iteration statements.
• Calling methods from classes within the .NET Class Library.

Getting Started

How do code blocks impact variable scope?

Code blocks play a crucial role in determining the scope of variable declarations. Variable scope refers to the visibility of a variable within your application’s code. A variable declared within a code block is locally scoped, meaning it is accessible only within that specific block. Attempting to access the variable outside the block will result in a compiler error.
