C语言课程设计_职工信息管理系统_结构体数组实现程序源代码_

1、/C语言课程设计 职工信息管理系统结构体数组实现#include #include #include struct employeechar num10;char name15;char sex5;char bm20;char zc20;int gz;int read_file(struct employee em;void menu(;void write_file(struct employee em;void add(; void select(; /查看职工所有信息void zc_query(; /按职称查询void num_del(; /按工号删除void tongji(; /统计v

2、oid sort(; /排序void num_modify(; /按工号修改职工信息void save(; /保存信息void disp(; /显示职工信息void fh(; /返回主菜单struct employee em300; /这个数组用来保存所有的职工信息 和文件里面的一致int Number=0; /记录总的职工人数 也就是数组/文件里面的职工人数void menu(printf("t*n"printf("t* *n"printf("t* 职工信息管理系统_结构体数组实现 *n"printf("t* *n&quo
