What is an infinite Loop? How is infinite loop declared?

Sometimes infinite loop also called Endless loop. Its having lacks a functional exit so that is repeats indefinitely. Or in other words, it's a loop which will not have a termination. It will continue execution until you break it by defining any breaking logic in the body of the loop.

You can integrate infinite loop as follows:

for( ; ; )

{

//Loop body

//Breaking logic for loop termination

}
