员工管理系统 (EMS)是一种软件，用于处理公司的主要内务管理功能。 EMS 帮助公司跟踪所有员工及其记录。它用于使用计算机化系统管理公司。
员工管理系统的目标：
- 建立员工表。
- 插入新条目。
- 删除条目。
- 搜索记录。
员工资料：
- 名称
- 员工ID
- 指定
- 经验
- 年龄
方法：
- 为了存储员工的数据，创建一个用户定义的数据类型来存储有关员工的信息。下面是数据类型的声明：
struct employee {
string name;
long int code;
string designation;
int exp;
int age;
};- 构建员工表：构建员工表的想法是使用上述结构数据类型的数组，该数组将用于存储有关员工的信息。为了在索引 i 处存储信息，数据存储为：
struct employee emp[10];
emp[i].name = "GeeksforGeeks"
emp[i].code = "12345"
emp[i].designation = "Organisation"
emp[i].exp = 10
emp[i].age = 10- 在记录中删除：由于我们使用数组来存储数据，因此删除任何索引处的数据都会将该索引处的所有数据移1，并通过将数组的大小减1来删除数组的最后一个数据。
- 在记录中搜索：对于基于任何参数在记录中搜索，其思想是遍历数据，如果在任何索引处的值参数与存储的记录匹配，则打印该员工的所有信息。
下面是C语言中员工管理系统的实现：
C++
// C++ program for the above approach
#include
#define max 20
using namespace std;
// Structure of Employee
struct employee {
string name;
long int code;
string designation;
int exp;
int age;
};
int num;
void showMenu();
// Array of Employees to store the
// data in the form of the Structure
// of the Array
employee emp[max], tempemp[max],
sortemp[max], sortemp1[max];
// Function to build the given datatype
void build()
{
cout << "Build The Table\n";
cout << "Maximum Entries can be "
<< max << "\n";
cout << "Enter the number of "
<< "Entries required";
cin >> num;
if (num > 20) {
cout << "Maximum number of "
<< "Entries are 20\n";
num = 20;
}
cout << "Enter the following data:\n";
for (int i = 0; i < num; i++) {
cout << "Name ";

}
// Function to insert the data into
// given data type
void insert()
{

return;
}
// Function to delete record

}
void searchRecord()

}
}

}
// Function to show menu
void showMenu()

int option;

// above option
if (option == 1) {

}
