如何在C中查找特定的记录？

typedef struct {
    char name[100];
    int age;
    int studentId;
} Student;

Student records[] = {
    {"Alice", 20, 1001},
    {"Bob", 22, 1002},
    {"Charlie", 21, 1003},
    // ...
};
int numRecords = sizeof(records) / sizeof(records[0]);

int findRecord(const Student* records, int numRecords, int studentId) {
    for (int i = 0; i < numRecords; i++) {
        if (records[i].studentId == studentId) {
            return i;  // 返回记录在数组中的索引
        }
    }
    return -1;  // 未找到记录
}

int main() {
    int targetId = 1002;
    int index = findRecord(records, numRecords, targetId);
    if (index != -1) {
        printf("Found record at index %d\n", index);
        printf("Name: %s\n", records[index].name);
        printf("Age: %d\n", records[index].age);
        printf("Student ID: %d\n", records[index].studentId);
    } else {
        printf("Record not found\n");
    }
    return 0;
}
