Explore how conditional statements control code execution in C# using if, else if, and else.

Learn how to use the if statement in C# to make decisions, enclose actions in braces, and see how true conditions execute while false ones skip.

Use comparison operators in if statements to drive C# program flow; evaluate conditions like greater than or less than, execute when true, and skip when false, and beware unreachable code.

Learn to program with C# from scratch focusing on conditional if statements, testing conditions with variables and comparison operators, and understanding when the if body executes.

Learn how C# uses if and else if statements to execute code based on conditions, evaluate conditions from top to bottom, and produce output when a condition is true.

Master the if-else conditional in C# by evaluating multiple conditions and executing the corresponding block when previous conditions are false, with results shown in a popup window.

Learn to use the ternary operator in C#, mastering its syntax, condition evaluation, and true/false branches to produce concise, conditional expressions and outputs.

See how the switch statement in C# executes a block based on a matching expression. Learn about switch, case, default, and break to understand how the program selects the block.

Explore how the switch statement in C-sharp selects code blocks by expression, using cases, a default, and breaks, illustrated with a month example.

Explore the three types of loops in c#, and learn to use while, do-while, and for loops to iterate over arrays and collections with conditions and curly braces.

This lesson introduces while loops in C-sharp, including do-while and for loops, and demonstrates a while loop that prints values from zero to six.

Demonstrate the do-while loop in C# by executing the loop body once before evaluating the condition and repeating while the condition is true, printing 0 through 6.

Learn how to use for and foreach loops in C#, including initialization, conditions, and increments. Iterate over arrays and print each item to the console using the write line method.

Explore break and continue statements in C# loops, showing how break exits a loop when a condition is met and continue skips the current iteration.

Learn to declare arrays in C# with square brackets to store multiple values in a single variable, and access items using zero-based indices.

Learn how to declare and define arrays in C# using square brackets, assign integer or string values, separate items with commas, and access values using the variable name.

Create string arrays in c# with the string keyword and square brackets, populate a fruits array with Apple, banana, fig, and cherry, and access items by index.

Access array elements using zero-based indices in C#. Retrieve the first, second, and third items—apple, banana, and fig—by index zero, one, and two, and display them with console WriteLine method.

Update array elements by index numbers to modify the first and second values of the fruits array in a C# program, then print the updated fruits to the console.
