Creating C# Loops

How to create C# Loops

The For Loop.

For loops are good when I need to loop through some code for a set number of times.  

Structure:

for (variable name = a number; a condition to meet; how many times)

{
the code that I want to repeat
}

Example:

for (int tictacs = 1; tictacs <= 10; tictacs++)

{
Console.Writeline(“I just ate {0} Tictacs”,tictacs)
}

Here is the result.

The While Loop

 The while loop loops through code based on a condition.

Structure:

while (variable <= a number)
{
process some code
}

Example:

//create an integer variable called MattsNumber and set it’s value to 1
int MattsNumber = 1;

//start the while loop.  While MattsNumber is less than or equal to 10 execute the code in the braces below.
while (MattsNumber <= 10)

{
//Increment MattsNumber by 1 every time we go through the loop.
MattsNumber++;
//Write some text and include what number we’re on
Console.Writeline(“The number is: {0}”,MattsNumber);

}

Console.Readline();

Here is the result:

The last loop for this post is the “Do While” Loop.  The do while loop is almost exactly the same as the while loop EXCEPT the code in the {} WILL RUN at least 1 time (even if the condition for the while loop is false).

Structure:

do
{
process some code
} while (variable <= a number);

Example

int MattsNumber = 1;

            do {

                MattsNumber++;

                Console.WriteLine(“The number is now {0}”, MattsNumber);

            } while (MattsNumber <= 10);

            Console.ReadLine();

Here is the result:
