用C语言写一个NBA球星管理系统

好的，下面是一个简单的NBA球星管理系统的C语言代码示例：

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

#define MAX_PLAYERS 100

struct player {
    char name[50];
    char position[20];
    int number;
    int age;
    float height;
    float weight;
};

struct player players[MAX_PLAYERS];
int num_players = 0;

int add_player() {
    struct player p;
    printf("Enter player name: ");
    scanf("%s", p.name);
    printf("Enter player position: ");
    scanf("%s", p.position);
    printf("Enter player number: ");
    scanf("%d", &p.number);
    printf("Enter player age: ");
    scanf("%d", &p.age);
    printf("Enter player height (in meters): ");
    scanf("%f", &p.height);
    printf("Enter player weight (in kilograms): ");
    scanf("%f", &p.weight);

    if (num_players < MAX_PLAYERS) {
        players[num_players] = p;
        num_players++;
        printf("Player added successfully.\n");
        return 1;
    } else {
        printf("Cannot add player. Maximum number of players reached.\n");
        return 0;
    }
}

void list_players() {
    if (num_players == 0) {
        printf("No players found.\n");
    } else {
        printf("Name\t\tPosition\tNumber\tAge\tHeight\tWeight\n");
        for (int i = 0; i < num_players; i++) {
            printf("%s\t\t%s\t\t%d\t%d\t%.2f\t%.2f\n", players[i].name, players[i].position, players[i].number, players[i].age, players[i].height, players[i].weight);
        }
    }
}

int search_player(char name[]) {
    for (int i = 0; i < num_players; i++) {
        if (strcmp(players[i].name, name) == 0) {
            return i;
        }
    }
    return -1;
}

int delete_player() {
    char name[50];
    printf("Enter player name: ");
    scanf("%s", name);
    int index = search_player(name);
    if (index == -1) {
        printf("Player not found.\n");
        return 0;
    } else {
        for (int i = index; i < num_players - 1; i++) {
            players[i] = players[i+1];
        }
        num_players--;
        printf("Player deleted successfully.\n");
        return 1;
    }
}

int update_player() {
    char name[50];
    printf("Enter player name: ");
    scanf("%s", name);
    int index = search_player(name);
    if (index == -1) {
        printf("Player not found.\n");
        return 0;
    } else {
        struct player p;
        printf("Enter player name: ");
        scanf("%s", p.name);
        printf("Enter player position: ");
        scanf("%s", p.position);
        printf("Enter player number: ");
        scanf("%d", &p.number);
        printf("Enter player age: ");
        scanf("%d", &p.age);
        printf("Enter player height (in meters): ");
        scanf("%f", &p.height);
        printf("Enter player weight (in kilograms): ");
        scanf("%f", &p.weight);
        players[index] = p;
        printf("Player updated successfully.\n");
        return 1;
    }
}

int main() {
    int choice;
    while (1) {
        printf("\nNBA Player Management System\n");
        printf("1. Add Player\n");
        printf("2. List Players\n");
        printf("3. Delete Player\n");
        printf("4. Update Player\n");
        printf("5. Exit\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                add_player();
                break;
            case 2:
                list_players();
                break;
            case 3:
                delete_player();
                break;
            case 4:
                update_player();
                break;
            case 5:
                exit(0);
            default:
                printf("Invalid choice.\n");
        }
    }
    return 0;
}

这个程序可以让用户添加、列出、删除和更新NBA球星的信息。其中，球星的信息包括姓名、位置、号码、年龄、身高和体重。程序使用了结构体来存储球员信息，并使用了数组来存储多个球员的信息。用户可以通过简单的菜单来进行操作。
