c - 如何为排序 vector 创建循环

Question

我有一个家庭作业问题要求我的代码读取一个 10 长度的 vector ，按升序排列它然后打印它。我正在尝试使用变量 int k 作为可数索引来执行此操作，其中代码验证 vector 中的特定位置是否大于其他位置，并为每个较小的变量将 1 添加到 k。然后，我创建了第二个 vector ，并为其第 k 个位置指定了第一个 vector 的值。汇编没有指出任何错误。代码运行，我通知 vector 的 10 个值，然后它返回一个大数字并崩溃。谁能帮帮我？提前致谢。

#include <stdio.h>
#include <stdlib.h>
#include <locale.h>

int main ()
{
    setlocale(LC_ALL, "Portuguese");
    //creates two double vectors
    double v[10], w[10];
    //creates a int variable to be a countable index
    int k = 0;
    //asks for the user to inform the values of the vector
    for (int i=0; i<=9; i++)
    {
        printf("Digite um número:\n");
        scanf("%lf", &v[i]);
    }
    //Here, I create this loop to verify whether each position of the vector v is greater than the other positions.
    for (int j=9; j>=0; j--)
    {
        //For the case j=9, I verify if it is greater than all the predecessor values, and add 1 to k for each case
        if (j==9)
        {
            for (int t=j-1; t>=0; t--)
            {
                if (v[j]>v[t])
                {
                    k+=1;
                }
            }
            //I attribute this value of v to the kth position of the new vector, and restart the countable index
            w[k]=v[j];
            k=0;
            continue;
        }
        //I do the same for the case in which j=0, verifying whether it is greater than the subsequent values
        else if (j==0)
        {
            for (int s=j+1; s<=9; s++)
            {
                if (v[j]>v[s])
                {
                    k+=1;
                }
            }
            w[k]=v[j];
            k=0;
            continue;
        }
        //For all the other values of the vector, I test both whether they are greater than the
        //predecessors and the subsequent values, and add 1 to k for each case
        else
        {
            for (int t=j-1; t>=0; t--)
            {
                if (v[j]>v[t])
                {
                    k+=1;
                }
            }
            for (int s=j+1; s<=9; s--)
            {
                if (v[j]>v[s])
                {
                    k+=1;
                }
            }
            //I attribute this value to the kth position of the new vector and restart the countable index
            w[k]=v[j];
            k=0;

        }
    //Here my loop ends
    }
    //I print the new vector
    for (int p=0; p<=9; p++)
    {
        printf(" %lf ",w[p]);
    }
    system("pause");
    return 0;
}

for (int s=j+1; s<=9; s--)应该有 s++ .我没有看到任何其他错误，但我会检查 gdb如果那不能解决问题。
