什么是静态变量?给我举个例子吗?

what is static varible?give me example?

推荐答案

C中有两种类型的静态变量:
全局静态变量在任何函数的主体外部声明，并且仅在该源文件中可见-在其外部看不到.

局部静态变量在函数内部声明，并将在后续的函数调用中保留其值:

There are two types of static variable in C:
A global static variable is declared outside the body of any function, and is visible only within that source file - it cannot be seen outside it.

A local static variable is declared inside a function, and will retain it''s value across sucessive function calls:

void myfunc()
   {
   static int i = 1;
   printf("%d\n", i);
   i += 1;
   }
void otherFunc()
   {
   myFunc();
   myFunc();
   }

将打印:

1
2

局部静态变量在声明该函数的函数之外仍然不可用.

A local static variable is still unavailable outside the function it is declared within.
