1.肯定是代码问题
2.第二个小分句是一个限制i的执行条件的语句，比如i < length就不执行这个循环了
你写的这个冒泡排序我实在是看不下去
3.你这个程序里没有用到#include <iomanip>和#include <cmath>这两个库，至于你说的有没有.h
有.h就是C头文件，没有.h就是C++头文件
C++从C借鉴过来在头文件开始有个c 就如 cmath 就是从 math.h来的
下面给你一个冒泡排序
所用语言C++，参考：算法导论
swap用了stl
void bubble_sort(int iarray[],int iarray_length)
{
for(int i = 0;i != iarray_length;++i){
bool swapped = false;
for(int j = iarray_length - 1;j != i;--j){
if(iarray[j] < iarray[j - 1]){
std::swap(iarray[j],iarray[j - 1]);
swapped = true;
}//end if
} // end inner for loop
if(!swapped) break;
}
}
交换排序没有听说过，只听说过
冒泡 选择 快速 堆 合并 计数 基数 桶 插入等排序方法
//交换排序法
for(i=length-1;i>=0;i++) //死循环，最终导致内存越界
{
max=c[i];
for(j=i;j>=0;j--)
{
if(max<=c[j])
{
max=c[j];
tempmax=j;
}
}
c[tempmax]=c[i];
c[i]=max;
}
修改如下：
//交换排序法
for(i=length-1;i>=1;--i)
{
max=c[i];
for(j=i-1;j>=0;j--)
{
if(max<c[j])
{
max=c[j];
tempmax=j;
}
}
if (max != c[i])
{
c[tempmax]=c[i];
c[i]=max;
}
}
代码问题，数组越界，for(i=length-1;i>=0;i++)
i永远是大于0的
