What are the types of loops?

Answer 1

There are three forms of loop commonly used in C/C++, the for loop, the while loop

and the do-while loop.

The for loop is most commonly used whenever an action is going to be performed a set amount of times. For example, to sum every element in an array:

for(i = 0; i < arraySize; i++)

{

sum = sum + array[i];

}

The while loop and do-while loop are commonly used to loop until a condition is met. The difference between the two is that the do-while loop goes through one iteration before checking its condition, while the while loop checks its condition before any execution of the loop.

Example do-while loop:

do

{

randomNumber = rand() % 10;

}while(randomNumber != 6);

Example while loop:

cout > number;

while(number < 0)

{

cout > number;

}

Answer 2

while (expression) statment

for (expression; expression; expression) statement

do statement while (expression) or you can use goto to implement a cycle (don't do that)

Answer 3

Three looping statements in C language are:

while (expression) statement

for (expression; expression; expression) statement

do statement while (expression)

LABEL: statements go to LABEL

(and of course recursion)

Answer 4

while, for, do-while, label-goto

Answer 5

The number differs between languages, but the most common are "for", "while", "do", and "each".
