求高手指点.......

楼主的问题是什么？你的缩进有大问题。。。

#include<stdio.h>
#include<stdlib.h>
main()
{
      int a[5]={4,3,2,1},b,i,j,k;
      for(i=0;i<5;i++)
      {
       b=0;
           for(j=1;j<4;j++)
           {
               if(a[i]>a[j])
               k=a[i];
               a[i]=a[j];
               a[j]=k;
               b=1;
           }
           if(b==0) break;
      }

      for(i=0;i<5;i++)
      {
          printf("%d\t",a[i]);
         
      }
      system("pause");
      return 0;
}
这个程序狗屁不通，一点都不像冒泡法，懒得再看了……

#include<stdio.h>

#include<stdlib.h>

main()

{

      int a[5]={4,3,2,1},b,i,j,k;

      for(i=0;i<5;i++)

      {

                      b=0;

                      for(j=1;j<4;j++//j=1排好也会被打乱的！
                      {

                                      if(a[i]>a[j])///木有{}第一分号后的都会被执行到看看if用法！
                                      k=a[i];

                                      a[i]=a[j];

                                      a[j]=k;

                                      b=1;

                                      }

                                      if(b==0)

                                      {break;}

                                      }

                                      for(i=0;i<5;i++)

                                      {

                                                      printf("%d\t",a[i]);

                                                      }

                                                      system("pause");

                                                      
return 0;
//格式缩进可以参考下标准程序！
 }

对于排序不用那么麻烦，用一个循环就够了

#include<stdio.h>
int main(void)
{
  int i=0,j=0;//定义两变量进行循环
  int tmp=0;//用于接收临时值班完成值的交换
  int num[5]={1,2,3,4,5};
  for(i=0;i<5;i++)
  {
    for(j=i+1;j<5;j++) //j=i+1是因为前面的数已经比较了，只需要跟i+1后的数进行比较就行了
    {
      //用数组中的第一个数分别和后面的所有的数比较大小，当碰到比第一个小的数时，把它们的值对换，这样循环完一次后第一个数一定是最小的，接着第二个数继续循环，得到第二小数，依此类推，整个循环结束时排序完成
      if(num[i]>num[j])
      {
        tmp=num[i];
        num[i]=num[j];
        num[j]=tmp;
      }
    }
  }
  //按从小到大的顺序依次输出
  for(i=0;i<5;i++)
    printf("%d",num[i]);
}

还有就是楼主调用的头文件stdlib.h是用于调用srand rand函数的，在这里暂时用不着
