WebNov 13, 2024 · Search: searching for an element in a data structure is another perfect use case for a while loop because we can't know in advance how many iterations will be needed to find the target value. For example, the Binary Search algorithm can be implemented using a while loop. WebIn C, and infinite loop is easy : iteration = 0; while (1) { printf ("On iteration %d", iteration); iteration ++; } That is an infinite loop - and it will run until you (or your O/S) intervenes - sometimes an O/S will shutdown process that consume too much CPU. If you have an empty loop : while (1) ;

WebIf x > m then we perform binary search on a new sorted list formed by the elements in L that are greater than m. So to prove binary search is correct, we need to check that the truth value of " x is in L " is preserved by 3. to 4. above. (1. and 2. form the base cases; there are actually infinitely many of them, but they're true by definition.)
