证明静态函数在main函数运行前就运行了

#include<iostream>#include<stdio.h>using namespace std;class static_name{public:static_name(){};static int  static_print();private:static  int  i_static_value;};int static_name::static_print(){printf("This is static!! i_static_value = %d\n", i_static_value);return 1;}int static_name::i_static_value = static_name::static_print();int main(){printf("This is main_function()!!\n");return 0;}
