NL.20: Don't place two statements on the same line
NL.20：不要在同一行上放置两个语句
Reason（原因）
Readability. It is really easy to overlook a statement when there is more on a line.
可读性。当一行上有更多语句时，很容易忽略某条语句。
Example（示例）
代码语言：javascript复制int x = 7; char* p = 29; // don't
int x = 7; f(x); x; // don't
Enforcement（实施建议）
Easy.
