To repeatedly perform the logic inside the loop while the condition holds true (you would expect something inside the code block to eventually cause the test condition to evaluate as false).
Most basic examples given in text books use an incrementing variable which could also be implemented as a for loop:
int i = 0;
do {
i++;
} while (i < 100);
A better example would be:
bool door_opened;
do {
door_opened = ring_doorbell(); /* an example function*/
} while (door_opened == false);
PS its probably 10 years since I wrote any C so syntax might not be 100% accurate.
Nothing.
The do while loop is also called an exit condition loop in c, c++, and java.
yes
In short, a for loop declares an variable and assigns it a value, has an argument, and has an update. A while loop only has an argument. More Detail... in C++, which is very close to C an example while loop is; while(i
In C a structure within a structure is called nested. For example, you can embed a while loop in another while loop or for loop in a for loop or an if statement in another if statement.
Available.
the counter variable cannot be initialized in while loop before entering into the block.
C, for loops, while loops, and do while loops are control structures forFor example, the following programs are functionally identical: While loop
do WHILE loop defination
No, why did you think so?
It is a statement; you can create a loop with it: while (<condition>) <statement>
An iteration is an instance of a structured loop statement (for, while or do-while).
Not all programmers will be comfortable with a "do-while" loop, just as not all programmers will be comfortable with the "for(;;)" loop.Both are provided for your individual preference.
