Define Entry Controlled Loop & Exit Controlled Loop?

Loop means, A sequence of statements are executed until
some conditions for termination of the loop are satisfied.
A program loop consists of 2 segments
1. Body of the loop &
2. Control statement.
The control statement tests certain conditions & then
directs the repeated execution of the statements contained in the body of the
loop.
Depending on the position of the control statement in the
loop, a control structure may be classified either as the entry may be
classified either as the entry controlled loop or as the exit–controlled loop.
Entry
controlled loop:
In the entry
controlled loop, the control conditions are tested before the start of the loop
execution. If the conditions are not satisfied, then the body of the loop will
be executed. It is also known as pre–test loop.
Exit
controlled loop:
In the case of an exit–controlled loop, the test is
performed at the end of the body of the loop execution. If the conditions are
not satisfied, then the body of the loop will not be executed. It is also known
as pre–test loop.
A looping process, would include the following 4 steps:
1. Setting & initialization of a condition,
variables.
2. Execution of the statements in the loop.
3. Test for a specified value of the con variable for
execution of the loop.
4. Incrementing or updating the con. Variable.
