An empty for statement should have the following form: for (initialization; condition; update) ; 1. place the brace at the end of the line that controls entry into the block * While statements: while (!done) { statements (); } ? Do-while statements: do { statements; } while (condition); 1. place the brace at the end of the line that controls entry into the block * Switch statements switch (condition) { case ABC : statements; case DEF : statements; break; ? case XYZ : statements; break; ? default : statements; } 2.Use a single space to separate the keywords, parentheses, and curly braces in conditional statements. * (条件语句中，比如if() for() while() try()，使用一个空格分隔关键词，括号和花括号。) for.( ...).{ ? // ... } 3. 不使用“hard”TAB 配置好编辑器，把对齐缩进时敲入的hardTab保存为空格。缩进使用4个空格。 VIM :set tabstop=4 :set expandtab * 4. White space Conventional operators should be surrounded by a space character. C++ reserved words should be followed by a white space. Commas should be followed by a white space. Colons should be surrounded by white space. Semicolons in for statments should be follow
