What is a loop?

Question

what do you mean by loop and what are its functions?

Answer 1

It's a loooooooop...
You may go round and round and round until the condition you have declared to terminate will not come.
looping statements are used to execute a part of program more than one time.
Let's say you want to divide a number 1000 by 2, and let it continue till the answer (quotient) will be 0, you use loop.
eg.
x=1000;
While(x!==0)
{
x=x/2;
}

Answer 2

A loop is a repetition, in meaning that it end where it start... To not infinitly repeat the loop, we associate mostly a ternary conditional test to decide or not to quit the loop at each iteration ( turn ), whatever at begin or end ( but this introduce a difference, that in case of testing at end, the loop is executed at least once, else the loop may be not executed at all ^^ ).

Answer 3

a loop generally refers to a for or while statement which will execute a block of code a specified amount of times. for example:

for (int i = 0; i < 10 ; i++)
{
console.writeline ("Hello");

}

//outputs "Hello" 10 times.

int i = 0; is the variable that will keep track of number of times the code has been executed.

i <10; specifies to keep doing this code while i is equal to less than 10.

and i++ is telling the loop to increment i by 1 each time.

Hope this helps.

Answer 4

A loop is a function which repeats (or re-runs) a statement until the condition for its termination is met. An example is when you write a code to flash 'PRESS ANY KEY TO CONTINUE' on the screen, The notification will continue flashing on the screen till any key (WHICH IS THE CONDITION FOR ITS TERMINATION) is pressed.
There are the WHILE, DO WHILE and FOR loop in C.
