Introduction

In this lesson, you will learn loops in C# for beginners. Loops help you repeat a block of code multiple times without writing it again.

What are Loops?

Loops are used to execute code repeatedly based on a condition.

Types of Loops in C#

for Loop

Used when you know how many times to run the loop:

for (int i = 0; i < 5; i++)
{
    Console.WriteLine(i);
}

while Loop

Runs while a condition is true:

int i = 0;

while (i < 5)
{
    Console.WriteLine(i);
    i++;
}

do-while Loop

Runs at least one time before checking condition:

int i = 0;

do
{
    Console.WriteLine(i);
    i++;
} while (i < 5);

Real-World Use

• Display lists of data
• Process multiple records
• Repeat tasks automatically

Key Points

• Loops reduce code repetition
• for loop is used for fixed iterations
• while loop is used for conditions
