Question 1
题目：（一维数组）有n个已经按由小到大排好序的整数，再输入一个整数，
将其插入到这批数据中，要求插入该元素后仍然按由小到大的顺序排列。#include <stdio.h>
#define N 11
void main()
{
int a[N], x, p;
int i;
printf("Please input %d numbers:", N - 1);
for (i = 0; i <= N - 2; i++)
scanf("%d", &a[i]);
printf("Please input x to be intert:");
scanf("%d", &x);
/**********Program**********/
/********** End **********/
for (i = 0; i <= N - 1; i++)//结果
printf("%5d", a[i]);
printf("\n");
}Answer:
for (i = 0; i < N - 1; i++)//寻找插入点，并将插入点保存到p中
{
if (a[i] > x)
{
p = i;
break;
}
}
printf("i=%d\n", p);
for (i = N - 2; i >= p; i--)//插入点之后元素后移一位，为新元素空出位置
a[i + 1] = a[i];
a[p] = x; //插入新元素If you have any mistakes or questions, please leave a message in the comment area for discussion.
