员工绩效管理系统c语言

员工绩效管理系统可以使用C语言编写。下面是一个简单的员工绩效管理程序的示例代码：

#include<stdio.h>
#include<stdlib.h>
#include<string.h>

struct employee {
    char name[20];
    int age;
    int salary;
    float rating;
};

int main() {
    struct employee emp[100];
    int i, n, choice;
    char ch;

    printf("Enter the number of employees: ");
    scanf("%d", &n);

    for(i=0; i<n; i++) {
        printf("Enter the details of employee %d:\n", i+1);
        printf("Name: ");
        scanf("%s", emp[i].name);
        printf("Age: ");
        scanf("%d", &emp[i].age);
        printf("Salary: ");
        scanf("%d", &emp[i].salary);
        printf("Rating: ");
        scanf("%f", &emp[i].rating);
    }

    do {
        printf("\n\n1. Display employee details\n");
        printf("2. Find highest rated employee\n");
        printf("3. Find highest paid employee\n");
        printf("4. Exit\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);

        switch(choice) {
            case 1:
                printf("\n\nEmployee Details:\n");
                for(i=0; i<n; i++) {
                    printf("Name: %s\n", emp[i].name);
                    printf("Age: %d\n", emp[i].age);
                    printf("Salary: %d\n", emp[i].salary);
                    printf("Rating: %.2f\n", emp[i].rating);
                    printf("\n");
                }
                break;

            case 2:
                printf("\n\nHighest rated employee:\n");
                float highest_rating = emp[0].rating;
                int index1 = 0;
                for(i=1; i<n; i++) {
                    if(emp[i].rating > highest_rating) {
                        highest_rating = emp[i].rating;
                        index1 = i;
                    }
                }
                printf("Name: %s\n", emp[index1].name);
                printf("Age: %d\n", emp[index1].age);
                printf("Salary: %d\n", emp[index1].salary);
                printf("Rating: %.2f\n", emp[index1].rating);
                break;

            case 3:
                printf("\n\nHighest paid employee:\n");
                int highest_salary = emp[0].salary;
                int index2 = 0;
                for(i=1; i<n; i++) {
                    if(emp[i].salary > highest_salary) {
                        highest_salary = emp[i].salary;
                        index2 = i;
                    }
                }
                printf("Name: %s\n", emp[index2].name);
                printf("Age: %d\n", emp[index2].age);
                printf("Salary: %d\n", emp[index2].salary);
                printf("Rating: %.2f\n", emp[index2].rating);
                break;

            case 4:
                printf("\n\nExiting the program...\n");
                exit(0);

            default:
                printf("\n\nInvalid choice. Try again.\n");
        }

        printf("\n\nDo you want to continue? (y/n): ");
        scanf(" %c", &ch);
    } while(ch == 'y' || ch == 'Y');

    return 0;
}

这个程序使用结构体来存储每个员工的姓名、年龄、薪水和绩效评级。程序提供了多个选项，例如显示员工详细信息、找到评级最高的员工等等。
