Because that expression is evaluated before each execution of the loop, a while loop executes zero or more times. The while loop differs from the do loop, which executes one or more times. The following example …Loops in Java. Looping in programming languages is a feature which facilitates the execution of a set of instructions/functions repeatedly while some condition evaluates to true. Java provides three ways for executing the loops. While all the ways provide similar basic functionality, they differ in their syntax and condition checking time.

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;Jan 7, 2010 at 2:31. 5. @Scott, that's true - I just meant that this code is equivalent to the OP's, even though it doesn't use a do/while. Although really, this code does half of the loop's "work" in the condition, so it's not quite a traditional while loop either - if the condition doesn't match, some work is still done.Nested do-while loop.

Statement: The …for ( int x = 0; x < 10; x++ ) {. cout<< x <<endl; } cin.get (); } This program is a very simple example of a for loop. x is set to zero, while x is less than 10 it calls cout<< x <<endl; and it adds 1 to x until the condition is met. Keep in mind also that the variable is incremented after the code in the loop is run for the first time.The reason your inner loop only executes once is because you initialize j to 0 outside the loop and then never reset it again. After it runs the first time the value of j is 10. It will never be less than 10 again. A better way to do this is to use a for loop: for (int i … While loop do while loop, [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1], [text-1-1]
