While and Do-While Loops
Learn about the while and the do-while loop constructs in C++.
Several programming tasks consist of executing the same code multiple times. Tasks like moving an object across the screen, iterating through a list of items, searching through data, and performing mathematical operations on a stream of numbers; all consist of a block of code being executed repeatedly till a termination condition is met. C++ allows executing the same code several times using two different loop constructs:
The
while
loop and its variation: thedo
-while
loop.The
for
loop
The while
Loop
The while
loop is really the only necessary repetition construct. The for
loop and the do
- while
loop, coming up shortly, can be replicated using a while loop.
