The printf function is called the format output function, and the last letter F of its keyword is the meaning of format. The function is to display the specified data to the display screen according to the user-specified format. We have used this

First, Brief introductionThe goal of the C language is to provide a programming language that compiles, processes low-level memory, produces a small amount of machine code, and can run without any running environment support in an easy way. It has
