while loop _ do while loop

// while loops and do while loops are used
// to execute a block of code repeatedly.

// here is what a while loop looks like
// while (condition)
// {
//     // code to execute
// }

// here is what a do while loop looks like
// do
// {
//     // code to execute
// }
// while (condition)

// let's make some real ones!

// here is a while loop that counts to 5
int count = 0;
while (count < 5)
{
    Console.WriteLine(count);
    count++;
}

Console.WriteLine($"The total count is {count}!");

// here is a do while loop that counts to 5
count = 0;
do
{
    Console.WriteLine(count);
    count++;
} while (count < 5);
Console.WriteLine($"The total count is {count}!");

// what happens if we change the condition to false
// for a while loop?
count = 0;
while (count > 5)
{
    Console.WriteLine(count);
    count++;
}
Console.WriteLine($"The total count is {count}!");

// what happens if we change the condition to false
// for a do while loop?
count = 0;
do
{
    Console.WriteLine(count);
    count++;
} while (count > 5);
Console.WriteLine($"The total count is {count}!");

// let's add a condition to the while loop
// so we can see the behavior of
// break and continue
count = 0;
while (count < 50)
{
    if (count == 3)
    {

        Console.WriteLine("I'm skipping 3!");
        continue;
    }

    Console.WriteLine(count);
    count++;

    if (count == 5)
    {
        Console.WriteLine("I'm out of here!");
