The difference is that in the //while// cycle the condition is checked before entering the loop, but in the //do while// cycle the condition is checked after execution of the statements in the loop and then if the condition is //TRUE// the loop repeats.

| + | **Check yourself** | ||
| + | |||
| + | 1. What loop where the condition is checked after the loop body is executed? | ||
| + | |||
| + | 2. How long will the operators in the body of the loop will operate (while (x < 100))? | ||
| + | |||
| + | 3. What value will be for variable //a// after code executing <code C> int a; for(a = 0; a < 10; a++) {} </ | ||
