a sentinel
A special value that marks the end of a list of values
a conditional loop
The loop that executes as long as a particular condition exists
a while loop
This is a conditional loop, pretest, repeats as long as a particular condition exists. It is ideal for situations where you don't want the loop to iterate if the condition is false from the beginning.
a for loop
This is a pretest loop that has a built-in expressions for initializing, testing and updating. It is ideal for performing a known number of iterations.
a do while loop
This loop is a conditional loop, but posttest, which means its express is tested after each iteration. It is ideal in situations where you always want the loop to iterate as least once.
a nested loop
This loop is inside another loop.
a count-controlled loop
This loop repeats a specific number of times
continue
This statement causes a loop to stop its current iteration and begin the next one.
a break
This statement causes a loop to terminate early.
Two categories of loops
a conditional loop and a count-controlled loop
loop
a control structure that causes part of a program to repeat
a counter
a variable that is regularly incremented or decremented each time a loop iterates
infinite loop
not having a way of stopping
postfix mode
the operator is placed after the variable
prefix mode
the operator is placed before the variable name
while loop format
while (expression) statement;
three loops
while loop, do while loop and for loop
three loops
while loop, do-while loop, for loop
