C++中对C语言结构体用法的扩充

#include <iostream>#include <ctime>using namespace std ;typedef struct student { private : int a , b , c ;  public : void set(int a , int b , int c) {  this->a = a ;   this->b = b ;   this->c = c ;  } void prit() {  cout << a << endl << b << endl << c << endl ; }}stu;stu st1 ; int main(void){ st1.set(1,2,3); st1.prit();  return 0 ;}
