Well, it should be noted that when the compiler lacks a punctuation mark in the code

The row number under the line of code in. Because the compiler does not know that a punctuation mark is missing in the code at the beginning

When compiling the following code, it is found that the end of the line of code that originally lacks punctuation marks should be ';' semicolon, and the result is compiled by the compiler.

Is a '{' Right braces, so the compiler will report an error in the line being compiled, and remind you that a punctuation mark may be missing before.
