It's easy for you to observe and what to suggest. %c and A are the corresponding relationships, and the content that you want to print out char must be stored in%c. And%c is storing the char data type.The "a" behind the data type is the so-called variable, which you can customize, the basic rules I will not say.Other types can then presumably other people say more than I do. Information is the accumulation of their own more and more, remember this!All things h
