C语言基础练习16

1.有n个整数，使前面各数顺序向后移m个位置，最后m个数变成最前面m个数

#include "stdafx.h"#include<stdio.h>int main(){void move(int[20], int, int);int number[20], n, m, i;printf("how many numbers?\n");scanf_s("%d", &n);printf("input %d numbers:\n", n);for (i = 0; i < n; i++)scanf_s("%d", &number[i]);printf("how many place you want to move?\n");scanf_s("%d", &m);move(number, n, m);printf("Now,they are:\n");for (i = 0; i < n; i++)printf("%d ", number[i]);printf("\n");    return 0;}void move(int array[20], int n, int m){int*p, array_end;array_end = *(array + n - 1);for (p = array + n - 1; p > array; p--)*p = *(p - 1);*array = array_end;m -- ;if (m > 0) move(array, n, m);}

运行结果：

2.编写一个函数print，打印一个学生的成绩数组，该数组中有5个学生的数据记录，每个记录包括num,name,score[3]

#include "stdafx.h"#include<stdio.h>#define N 5struct student{char num[6];char name[8];int score[3];}stu[N];int main(){void print(struct student stu[6]);int i, j;for (i = 0; i < N; i++){printf("\ninput score of student %d:\n", i + 1);printf("No.:");scanf_s("%s", stu[i].num,6);printf("name:");scanf_s("%s", stu[i].name,8);printf("score:");scanf_s("%d%d%d", &stu[i].score[0], &stu[i].score[1], &stu[i].score[2],3);printf("\n");}print(stu);    return 0;}void print(struct student stu[6]){int i, j;printf("\n  No.      name     score1     score2     score3\n");for (i = 0; i < N; i++){printf("%5s%10s", stu[i].num, stu[i].name);for (j = 0; j < 3; j++)printf("%9d", stu[i].score[j]);printf("\n");}}

运行结果：

3.13个人围成一圈，从第1个人开始顺序报号1，2，3。凡报到3者退出圈子。找出最后留在圈子中的人原来的序号。

#include "stdafx.h"#include<stdio.h>#define N 13struct person{int number;int nextp;}link[N+1];int main(){int i, count, h;for (i = 1; i <= N; i++){if (i == N)link[i].nextp = 1;elselink[i].nextp = i + 1;link[i].number = i;}printf("\n");count = 0;h = N;printf("sequence that person leave the circle:\n");while (count < N - 1){i = 0;while (i != 3){h = link[h].nextp;if (link[h].number)i++;}printf("%4d", link[h].number);link[h].number = 0;count++;}printf("\nThe last one is: ");for (i = 1; i <= N; i++)if (link[i].number)printf("%3d", link[i].number);printf("\n");    return 0;}

运行结果：
