结构体指针
参考http://www.cplusplus.com/doc/tutorial/structures/
#include <stdio.h> struct People{ int age; }; int main(int argc, const char * argv[]) { struct People *p = malloc(sizeof(struct People)); p->age = 10; struct People *p1 = p; p->age = 12;//p1的值也会改变，如果不是指针类型则不会有影响 printf("age:%d ", p1->age); free(p);//释放内存 system("pause"); return 0; }
