C language) when writing a program, if you can't write one line, how can you continue writing on the second line?

There can be no other visible characters in the program. Only line breaks, spaces and tabs can be ignored. In other words, you hit Enter N times in a row, just like you didn't. The program automatically skips line breaks to find the next character. Follow-up: The original text in my C program book is like this: "A statement of C program can be written on several lines with continuation symbols." Answer: The continuation characters in C language are defined by macros, that is, by hand. \ A backslash. . But there is a rule that \ must be immediately followed by a carriage return. There are other characters who can't get through it. The function of this symbol is to remind people to see. According to the macro definition, the machine will ignore it, essentially leaving only line breaks. You got it? When you see it, you will know that there should be something behind it, instead of forgetting to write it; Semicolon.
