Question

用C++编写函数，将n=4插入有序数据中，插入后数组仍然有序。提示：主函数定义a[10]={1,2,3,5,6,7,8,9,10}

插入数n=4，调用函数 void fu(int b[],n） 实现调用

Answer 1

#include <iostream>
using namespace std;
void fu(int b[], int n)
{
int i;
for (i = 8; i >= 0; i--)
{
if (b[i] > n)
{
b[i + 1] = b[i];
}
else
{
b[i + 1] = n;
break;
}
}
}
int main()
{
int a[10]={1,2,3,5,6,7,8,9,10};
int n = 4;
fu(a, n);
int i;
for (i = 0; i < 10; i++)
{
cout << a[i] << " ";
}
return 0;
}

Answer 2

void fu(int b[], n)
{
int i = 0, j = 0;
for(; i < sizeof(b)/4; i++)
{
if(b[i] > n)
{
b[i] = n;
for (; j = i + 1; j < sizeof(b) / 4; j++)
{
b[j] = b[j-1];
}
break;
}
}
}
