Code Maintenance & Programming Rules

 This guide outlines essential best practices spanning code style, architectural design, debugging, testing, performance, and portability—all aimed at reducing the long-term cognitive load of code maintenance. 🎨 1. Style Code is written for humans to read, and only incidentally for computers to execute. Variable Naming : Use descriptive names for global variables, and short names for local variables. Precision and Consistency : Use active names for functions (e.g., calculateTotal ). Above all, keep your coding style consistent throughout the project. Structure & Expressions : Use a consistent indentation and brace ( {} ) style to show program structure visually. Use the natural form for expressions. Use parentheses to make the semantics unambiguous. Break up overly complex expressions to keep them clear. Side Effects & Macros : Beware of functions with side effects. Avoid function-like macros; if unavoidable, parenthesize the macro body and arguments carefully. Magic Numbe...

代數:矩形面積應用


假設
\[ \large a = 99 , b = 5, c = 19 \]

那下列式子的值為多少?
\[ \large 1 + a + b + c + ab + bc + ca + abc \]

\[ \large (a + 1) \times (b + 1) \times (c + 1) = \]
\[ \large (ab + a + b + 1) \times (c+1) = \]
\[ \large abc + ab + ac + c + bc + b + c + 1\]
所以答案為\[ \large (99 + 1) \times (5 + 1) \times (19 + 1) = \color{blue}{12000} \] 若您覺得文章寫得不錯,請點選文章上的廣告,來支持小編,謝謝。
