這篇文章主要為大家詳細(xì)介紹了C語言實現(xiàn)學(xué)生選課系統(tǒng)，具有一定的參考價值，感興趣的小伙伴們可以參考一下
本文實例為大家分享了C語言實現(xiàn)學(xué)生選課系統(tǒng)的具體代碼，供大家參考，具體內(nèi)容如下
#include <stdio.h>
#include <stdlib.h>
#include <malloc.h>
#include <string.h> 

typedef struct curr
{
char name[20];  //課程姓名 
int number; //課程序號   
char teacher[20]; //課程教師姓名 
int time; //課程課時 
int classroom; //課程教室 
struct curr *next; //鏈表next 
}curr,*pcurr;


typedef struct stu
{
int number; //學(xué)生序號 
char name[20]; //學(xué)生姓名 
char sex[20]; //學(xué)生性別 
struct curr *choices; //學(xué)生選課 
struct stu *next; //鏈表next 
}stu,*pstu;




pcurr creat_curr(pcurr curr_head);  //創(chuàng)建鏈表，課程信息 
pcurr find_curr(pcurr curr_head,int number);  //查找鏈表， 課程信息 
pcurr add_curr(pcurr curr_head,pcurr new_curr); //課程信息加入鏈表
