If you don't need a global variable, try to use a local variable.

如果你不需要全局变量，尽量使用局部变量。

Incrementing a local variable in a method is the fastest.

在方法中递增局部变量,速度是最快的.

Explain local variable declarations with an end - line comment.

使用行尾注释解释局部变量声明.

Incrementing an undefined local variable is 9-10 times slower than a pre-initialized one.

递增一个未预定义的局部变量要比递增一个预定义的局部变量慢9至10倍。

The lifetime of a local variable is limited to the lifetime of the block in which it is declared.

局部变量的生存期被限制为定义它的块的生存期。
