Repetition is the use of a for loop to execute one piece of code over and over. There are multiple ways to create a for loop though. These are:

  • While uses one condition that which if met, will repeat the code.
1              while (true)
2                 {
3                    x ++
4                 }
  • For loops intialise a variable, check a condition and perform an action. This is done before each iteration.
1 for (int i = 0; i <= 1000000; i++)
2                     {
3                     }
  • Do while is the same as a while, however it doesn't check until it has done one iteration
1  do {
2     x ++
3    }
4    while (true)
