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)
