C# While Loop

While Loop

The while loop in C# allows you to repeatedly execute a block of code as long as a certain condition is true. The syntax for a while loop is as follows:

while (condition)
{
    // code to execute as long as condition is true
}

For example, consider the following code snippet:

int i = 0;
while (i < 10)
{
    Console.WriteLine(i);
    i++;
}

In this example, the code inside the while loop will be executed 10 times, with the value of i being printed to the console each time. On the first iteration, i is 0, so the condition i < 10 is true and the code inside the loop is executed. On the second iteration, i is incremented to 1, and the condition is still true, so the code inside the loop is executed again. This process continues until i is incremented to 10, at which point the condition i < 10 is false and the loop is exited.

do-while Loop

C# also provides a do-while loop, which is similar to a while loop, but the code inside the loop is always executed at least once. The syntax for a do-while loop is as follows:

do
{
    // code to execute at least once
}
while (condition);

For example, consider the following code snippet:

int i = 0;
do
{
    Console.WriteLine(i);
    i++;
}
while (i < 10);
