Welcome to C sharp programming! Today we'll explore loop structures, which are fundamental programming constructs that allow us to repeat code execution. Loop structures help us avoid writing repetitive code and efficiently control program flow based on conditions or collections.
The for loop is the most commonly used loop structure in C sharp. It consists of three parts: initialization, condition, and increment. The loop starts by initializing a variable, then checks the condition before each iteration, and increments the variable after each execution. This flowchart shows how the for loop executes step by step.
While and do-while loops are condition-based loops in C sharp. The while loop checks the condition before executing the code block, which means it might not execute at all if the condition is false initially. The do-while loop executes the code block first, then checks the condition, guaranteeing at least one execution. This flowchart comparison shows the key difference in their execution order.
