根据学号查询成绩和根据姓名查询成绩调用函数两种方法 c语言

1. 根据学号查询成绩

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

struct Student {
    char name[20];
    int id;
    int score;
};

void searchById(struct Student s[], int n, int id) {
    int i;
    for (i = 0; i < n; i++) {
        if (s[i].id == id) {
            printf("Name: %s\n", s[i].name);
            printf("ID: %d\n", s[i].id);
            printf("Score: %d\n", s[i].score);
            return;
        }
    }
    printf("No record found for ID %d\n", id);
}

int main() {
    struct Student students[3] = {{"Alice", 1001, 85}, {"Bob", 1002, 90}, {"Charlie", 1003, 95}};
    int id;
    printf("Enter ID to search: ");
    scanf("%d", &id);
    searchById(students, 3, id);
    return 0;
}

2. 根据姓名查询成绩

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

struct Student {
    char name[20];
    int id;
    int score;
};

void searchByName(struct Student s[], int n, char* name) {
    int i;
    for (i = 0; i < n; i++) {
        if (strcmp(s[i].name, name) == 0) {
            printf("Name: %s\n", s[i].name);
            printf("ID: %d\n", s[i].id);
            printf("Score: %d\n", s[i].score);
            return;
        }
    }
    printf("No record found for name %s\n", name);
}

int main() {
    struct Student students[3] = {{"Alice", 1001, 85}, {"Bob", 1002, 90}, {"Charlie", 1003, 95}};
    char name[20];
    printf("Enter name to search: ");
    scanf("%s", name);
    searchByName(students, 3, name);
    return 0;
}
