C语言变量的初始化

#include "stdio.h"
int a;
int main(int argc, char const *argv[])
{
int b;
static int c;
printf("global variable = %d\n", a);
printf("auto variable = %d\n", b);
printf("static variable = %d\n", c);

return 0;
}

终端输出：

Administrator@WIN7-20150725PK ~

$ gcc test1.c

Administrator@WIN7-20150725PK ~

$ ./a.exe

global variable = 0

auto variable = 2280620

static variable = 0
