Loops: while(), for() and do .. while() Comments and questions to John Rowe. In the previous lecture we learnt about logical statements that determine whether or not code gets run. Here we learn about loops which allow sections of code to run zero or more times, with a controlling logical expression. The while() loopThis is equivalent to a for loop, looping the index variable i over the array A.It has O(n). Keep in mind that big-O notation denotes the worst possible time taken by the algorithm, and if the desired element is at the end of the array, you will execute the loop n times, and the loop has a constant cost. Therefore, you will execute kn operations, for …

The first code sample is pretty much a classis for loop. Its complexity is O (n^2). This is because the inner loop has a complexity O (n) and it is run n times. The second one is a bit more difficult, untill you see that is equivalent to a non nested loop (ignoring the complexity of the checks) int result = 0; int i = 0;Summary. Looping statements are used to execute the same block of code again and again. You will use Do-While, Do-Until and While-Wend loops when you do not know in advance how many times the block is to be executed.

While running these loops, there may be a need to break out of the loop in some condition before completing all the iterations or to restart the loop before completing the remaining statements. This can be achieved with the ‘break’ and ‘continue’ statements. It is really simple. The For loop repeats the while loop, the while loop adds an extra number to i and then it repeats.
