Although the computer is very powerful:
It can be used for you to surf the Internet, play games and manage the company's personnel relations. But without a program, it is equivalent to a pile of scrap iron and will not pay attention to the "orders" we give it. Therefore, we can only tame it in one way-program, which is the only way for us to communicate with computers. A program is a collection of instructions that tell a computer how to perform a special task.
For example, it is like guiding you to make a menu, or directing a traffic policeman (or a traffic sign) to drive all the way to the destination. Without these special instructions, the expected task will not be carried out.
