Whats the use of while-loop

[iamnoob15]

In what kind of problem can I use while-loop?

[keskiverto]

int a;
while ( cin >> a ) 
{
  cout << a;
}

how do you get out of that while loop?

Enter an EOF character on the keyboard (ctrl-C on windows).

while loops are best suited for a section of code that you want to execute while some condition is true. This is in contrast to a for loop which is usually used when you want to execute the loop a fixed number of times.

It's Ctrl+Z, because Ctrl+C is to break/terminate the program.
