- Learn the operators and techniques required to evaluate and compare values in your decision statements.
After you complete this module, you'll be able to:
Use operators to create Boolean expressions that test for comparison and equality.
Use built-in methods to the string class to perform better evaluations on strings.
Use the negation operator to test for the opposite of a given condition.
Use the conditional operator to perform an inline evaluation.
- Use code blocks with more confidence, understanding how they impact the visibility and accessibility of both higher and lower-level constructs in your code.
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.
- Learn how to add branching logic that matches one variable or expression against many possible values.
After you complete this module, you'll be able to:
Use the switch-case construct to match a variable or expression against several possible outcomes.
Convert code that uses an if-elseif-else construct into a switch-case construct.
- Use the for iteration statement to loop a pre-set number of times and control the iteration process.
After you complete this module, you'll be able to:
Use the for statement to loop through a block of code
Modify how the .NET Runtime executes the looping logic, changing the value of the iterator, the condition and the pattern
- Use the do-while and while statements to iterate as long as a Boolean expression evaluates to true.
After you complete this module, you'll be able to:
Write code that uses the do-while statement to iterate through a code block
Write code that uses the while statement to iterate through a code block
Use the continue statement to step directly to the Boolean evaluation
- Gain experience developing a console app that implements selection and iteration statements to achieve app specifications.
In this module, you'll practice how to:
Use Visual Studio Code to develop a C# console application that uses a combination of selection and iteration statements to implement logical workflows in accordance with supplied application data and user interactions.
Evaluate the underlying conditions and make an informed decision when choosing between if-elseif-else and switch statements, and between foreach, for, while, and do iteration statements.
Scope variables at an appropriate level within an application.
