And, if you are completely new to programming then as well you need not worry as the discussions in this article is at absolute beginner level and you are not required to have a programming background. Use iteration (while loop) to solve this problem. Go to the editor Expected Output: 1 2 3 4 5 6 7 8 9 10 {
Write a C program to print all natural numbers from 1 to n. - using while loop. for vs. while •you will probably use forloops more •foris natural to loop through a list, characters in a string, etc. - using while loop. System.out.println("c. break");
The condition is evaluated again. In programming, loops are used to repeat a block of code until a specified condition is met.

These PHP Loop exercises contain programs on PHP for Loop, while Loop, mathematical series, and various string pattern designs. WhileLoopDemo demo = new WhileLoopDemo();
The following example uses do-while loop, another C/C++ construct that can be used for repetition. A while loop ends if and only if the condition is true, in contrast to a for loop that always has a finite countable number of steps. Load History. Console.WriteLine("Please press y to begin the test..");

4. So (i % 5 == 0) is seeing if some value i divided by 5 will have a remainder of 0. Unlike a For Loop, While Loop execution does not depend on iteration count; thus, a While Loop executes indefinitely if the condition never occurs. {
}, One more way for Exercise 1:
}
{
Console.ReadLine();
Console.WriteLine("B) continue");
You probably found out by looking at other websites and stuff but the % sign computes division and collects the remainder.
// Instantiation. Note: The important point to note when using while loop is that we need to use increment or decrement statement inside while loop so that the loop variable gets changed on each iteration, and at some point condition returns false. The loop iterates while the condition is true. // Class that will help to Read and Answer the question. a. int. See the example below: What is the command keyword to exit a loop in C#? do

Loops in C/C++ come into use when we need to repeatedly execute a block of statements.. During the study of ‘for’ loop in C or C++, we have seen that the number of iterations is known beforehand, i.e. 2. Console.WriteLine();
When condition returns false, the control comes out of loop and jumps to the next statement after while loop. break;
It is recommended you solve all the programming problems using loop constructs. Here, the key point to note is that a while loop might not execute at all. Here, the test_expression is i < 6 which evaluates to TRUE since 1 is less than 6. Console.WriteLine("b. continue");
