Control variable scope and logic using code blocks in C#
Use code blocks with more confidence, understanding how they impact the visibility and accessibility of both higher and lower-level constructs in your code.
Learning objectives
After you complete this module, you'll be able to:
- Understand the impact of declaring and initializing variables inside and outside of code blocks
- Remove code blocks in if statements to improve readability when there's only one line of code in the body of the code block
- Describe the purpose and scoping hierarchy for namespaces, classes, and methods
Prerequisites
- Experience creating simple C# applications that include console I/O and access the methods of .NET classes such as String and Random
- Experience using Visual Studio Code to develop, build, and run C# console applications that implement arrays, if-elseif-else statements, and foreach statements
- Experience using operators to evaluate an expression or condition in C#
