Difference between Entry and Exit Control Loops or the Difference between while and do while loop
Difference between Entry and Exit Control Loops or the Difference between while and do while loop
Three types of control statements in C++:
Decision making statements (if, switch)
Iterative statements/Loop statements
Jump statements (break continue, Go to.)
Loops came into the picture when we need to repeatedly execute a block of statements.
Loops are the technique to repeat statements until a given condition is true.
This kind of repetition is also called iteration.
Used to reduce the code’s redundancy.
Loops are controlled either at the entry-level or at the exit level hence loops are of two ways:
Entry Controlled loops
Exit Controlled Loops
Entry Controlled loops: The test condition is evaluated before entering the loop body and if that condition is true then the block of the statement will be executed.
Exit Controlled Loops: The test condition is evaluated at the end of the loop body. Therefore, the loop body will execute at least once, irrespective of whether the test condition is true or false.
