stru_fun01.cpp

在c环境下的对数据结构进行讲解,包含有例题及答案

//stru_fun01.cpp	以参数传递
#include <iostream.h>		//cin,cout
#include <stdlib.h>		//random()
#include <conio.h>		//getch()
struct rec
{ int chi,eng,math,total;
  float ave;
};
//原型声明
void get_data(rec *);
void output_data(rec *);
void main()
{ rec Bill;				//一般结构变量
  get_data(&Bill);		//传地址
  cout << "数据如下:\n";
  output_data(&Bill);
  getch();
}
//get_data
void get_data(rec *a)		//指针接收
{ a->chi  = random(101);
  a->eng  = random(101);
  a->math = random(101);
  a->total = a->chi + a->eng + a->math;
  a->ave = a->total/3.0;
}
//output_data
void output_data(rec *a)	//指针接收
{ cout <<"语文="    <<a->chi;
  cout <<"\n英语="  <<a->eng;
  cout <<"\n数学=" <<a->math;
  cout <<"\n总分="<<a->total;
  cout <<"\n平均="  <<a->ave<<"\n";
}
