本文实例为大家分享了C语言实现宿舍管理系统的具体代码，供大家参考，具体内容如下
本次大一课设的作品，从空项目开始写的，全部在txt文件中增改删。变量命名太土了，代码格式还有待优化，望大佬指点。程序有个缺点就是不能把字符串互相对齐，看着不美观。mysubstr是参考了论坛某位大佬的代码，再此感谢。
主界面是这样的
以下为源代码：
#include<stdio.h>
#include<string.h>
#include<process.h>
#include<coNIO.h>
#define MAX_LINE 1024
#include<malloc.h>
#include <assert.h>
char* mysubstr(char* srcstr, int offset, int length) {
assert(length > 0);
assert(srcstr != NULL);
int total_length = strlen(srcstr);
int real_length = ((total_length - offset) >= length ? length : (total_length - offset)) + 1;
char *tmp;
if (NULL == (tmp=(char*) malloc(real_length * sizeof(char)))) {
printf("Memory overflow . \n");
exit(0);
}
strncpy(tmp, srcstr+offset, real_length - 1);
tmp[real_length - 1] = '\0';
return tmp;
} //首先获取srcstr的长度
//判断srcstr的长度减去需要截取的substr开始位置之后，剩下的长度
//是否大于指定的长度length，如果大于，就可以取长度为length的子串
//否则就把从开始位置剩下的字符串全部返回。
int open=0,n,house=0;//open为判断是否登录的变量，登录为1否则为0
