Most of the time we create infinite loops by mistake. However, if we forgot to write the last statement (i=i+1), then, loop will never terminate and hence will become an infinite loop. An infinite loop continues to repeat until the program is interupted. An infinite loop must have an exit condition that has to be executed once the goal of the program has been met.
