Detailed explanation-1: -And the “forever” block will repeat a set of statements forever, never stopping until you click on the red stop sign icon on the screen to end your program.
Detailed explanation-2: -Blocks of repeating code are called loops. The C while loop can be set up to repeat a code block while some condition is true. A while loop can also be set up to repeat endlessly, but there is a trick for escaping endless loops as well.
Detailed explanation-3: -Looping forever To do this, Scratch provides you with the forever block which allows you to repeat a sequence of commands forever. The sequence of commands you place inside the block will be executed continually by your computer until you stop your program.
Detailed explanation-4: -An infinite loop is also known as an endless loop. The Forever block is a Control block. Blocks that are inside the forever block will be in an infinite loop so repeated continuously without end. Once this block is activated, all blocks inside forming an endless loop.
