求教各位，我的程序代码如下，是在Visual Studio中写的；
已经定义好的数组在排序之前是没有问题的，但排序过后就会出问题，Release时而有问题，Debug是每次必出问题；
求大神指点

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

void maopao(int a[]);
void exchange(int *a, int *b);

#define LENGTH 100

int main()
{
    int a[LENGTH],counter=0;
    srand(time(NULL));
    while (1)
    {
        for (counter = 0;counter < LENGTH; counter++)
        {
            a[counter] = rand() % 100000;
        }
        maopao(a);
        printf("\nIt's over\nPress ENTER to run again\n");
        getchar();
    }
    return 0;
}
void exchange(int *a, int *b)
{
    int temp;
    temp = *a;
    *a = *b;
    *b = temp;
}
void maopao(int a[])
{
    int i,j,output;
    printf("Before:\n\n");
    for (output = LENGTH - 1;output >= 0;output--)
    {
        printf("\tNo.%d\t=%d\n ", output + 1, a[output]);
    }
    printf("\n\n\n");
        for (i=0;i<=LENGTH-1;i++)
        {
            for (j = 0;j <= LENGTH-i;j++)
            {
                if (a[j] > a[j + 1])
                    exchange(&a[j], &a[j + 1]);
            }
        }
        printf("After:\n\n");
        for (output = LENGTH-1;output>=0;output--)
        {
            printf("\tNo.%d\t=%d\n ",output+1, a[output]);
        }
}

嗯，谢谢，我再看看吧

这个代码没问题

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

void maopao(int a[]);
void exchange(int *a, int *b);

#define LENGTH 100

int main() {
  int a[LENGTH], counter = 0;
  srand(time(NULL));
  for (counter = 0; counter < LENGTH; counter++) {
    a[counter] = rand() % 10000;
  }
  maopao(a);
  for (int output = 0; output < LENGTH; ++output) {
    printf("a[%d]=\t%d\n", output, a[output]);
  }
  return 0;
}
void exchange(int *a, int *b) {
  int temp;
  temp = *a;
  *a = *b;
  *b = temp;
}
void maopao(int a[]) {
  int i, j, output;
  for (i = 0; i < LENGTH; i++) {
    for (j = 0; j < LENGTH - i - 1; j++) {
      if (a[j] > a[j + 1]) {
        exchange(&a[j], &a[j + 1]);
      }
    }
  }
}
