In the preceding code, the while loop checks the condition (i <= 10)
that evaluates to true. The statements written inside the body of the
while loop get executed. The value of the variable i will be incremented
by 1 (i++). The loop checks the condition again and again until the
value of the variable i becomes more than 10. This variable is also
called a control variable. The control variable defines the duration
until which the loop will execute.

The do-while Loop

The do-while loop is similar to the while loop. The only difference is
that the do-while loop will execute the statements written inside its Start
body at least once, whether the given condition returns true or false.
The do-while loop executes the statements written inside its body Body of do...while loop
and checks the condition. If the condition evaluates to true, the loop
will execute again and again until the given condition becomes false.

The syntax of the while loop is as follows:
True Conditional
do Expression

{
False
[statements]
Stop
[increment/decrement expression]
} Flowchart of do-while loop

while(< conditional expression >);
