用结构体输入输出一个学生的信息

Question

定义学生数据类型 struct Student ，输入输出学生的信息

Answer 1

#include<stdio.h> #include<malloc.h> int i; struct Student { char name[100]; //char mingzi[100]; int age; //int nianling; float score; //char fenshu; }; void shuru(struct Student * p1, int a) { for (i = 0; i < a; i++) { printf("请输入第 %d 位学生的信息。\n", i+1); printf("name = "); scanf("%s", p1[i].name); printf("age = "); scanf("%d", &p1[i].age); printf("score = "); scanf("%f", &p1[i].score); } } void paixu(struct Student * p2, int n) { struct Student t; for (i = 0; i < n - 1; i++) { for (int j = 0; j < n - 1 - i; j++) { if (p2[j] .score < p2[j + 1].score) // 大于是升序 小于是降序 { t = p2[j]; p2[j] = p2[j + 1]; p2[j + 1] = t; } } } } void shuchu(struct Student * p3, int b) { for (i = 0; i < b; i++) { printf("第 %d 名学生的信息为: \n", i+1); printf(" 姓名: = %s\n", p3[i].name); printf(" 年龄: = %d\n", p3[i].age); printf(" 分数: = %.2f\n", p3[i].score); } } int main(void) { int n; struct Student * p; printf("请输入学生的个数: n = "); scanf("%d", &n); printf("\n"); p = (struct Student *)malloc(n * sizeof(struct Student)); shuru(p, n); paixu(p, n); printf("\n\n"); shuchu(p, n); return 0; }
