Countdown to launch

Is used to repeat an indented section of code underneath the statement a known number of times.

Note The `while` command is used when you don't know how many iterations will be required, but `for` is used when the number of iterations is known.

Although you can use a while loop instead of a for loop as shown in the example below, it is not considered good practice unless the value of counter can be changed by another command in addition to the increment statement.

int counter = 0;

while (counter < 5)

{

counter = counter + 1; // This is the increment statement.

}

The syntax for a for loop is:

for (initalisation, condition, change)

{

// Code block to be executed.

}

The initialisation statement is executed first and only once. Usually, it sets a variable before the loop starts. The condition statement defines the condition for the loop to run – if it is true, the loop will repeat the code inside it, otherwise the loop will end. The change statement changes the variable initialised in the initialisation statement at the end of every iteration of the loop.

E.g.

for (int counter = 0; counter < 5; counter++)

{

Console.WriteLine(counter);

}
