The while construct

A loop is used in the programming world to make a sequence of execution steps repeat itself until the condition is met. The while loop is one of the building blocks of the C# programming architecture and is used to loop through the body mentioned in curly brackets until the condition mentioned in the while criteria is true:

while (condition)
{
  loop body;
}

The condition mentioned in the loop should evaluate to true to execute the loop for the next iteration.
