Steps in loop control

Answer 1

C has 3 types of loops.

do

{

foo += increment;

}

while(foo != bar);

This loop will continue until foo equals bar but will execute the loop at least once, even if foo equals bar. The variable increment may be changed within the do loop. It is imperative that the value foo can reach equality with bar, otherwise an endless (run for ever) loop condition exists.

*****

while(foo != bar)

{

foo += increment;

}

The loop will continue until foo equals bar but will not execute if foo equals bar.

The variable increment may be changed within the do loop. It is imperative that the value foo can reach equality with bar, otherwise an endless (run for ever) loop condition exists.

*****

for (foo = 0; foo < bar; foo+= increment)

{

}

The loop will continue until foo equals bar. The stepping amount is controlled by the value of increment. The value of increment could be changed inside the loop.
