引用和指针-源码实例

结构体的赋值，有两种方法：使用元素引用赋值，使用指针赋值。

源码:

#include

 

struct test

{

       int a;

       char * str;

};

 

int main()

{

       struct test m_test;

      

       printf("--------------1------------\n");

       printf("struct value by reference\n");

 

       m_test.a = 123;

       m_test.str = "string";    

 

       printf("a = %d\n str:%s\n",m_test.a,m_test.str);

 

       {

              struct test n_test;

              struct test *pst;

             

              printf("\n--------------2-------------\n");

              printf("struct value by pointer\n");

              pst = &n_test;

              pst->a = 234;

              pst->str = "hello";

             

              printf("a = %d\n str:%s\n",pst->a,pst->str);

             

             

       }

      

}
