int main()
{
    int i,j,p;
    int a[N]={12,25,48,79,86,26,32,45,96,82};
    for(i=1;i<=N;i++)
        for(j=1;j<=N-i;j++)
        if(a[j]>a[j+1])
            p=a[j];

            a[j+1]=p;
    for(i=1;i<=N;i++)
        printf("a[%d]=%d\t",i,a[i]);
}

下次贴代码 要贴完整代码   从#include 开始贴

#include<stdio.h>

#define N 10

int main()
{
    int i,j,p;
    int a[N]={12,25,48,79,86,26,32,45,96,82};
    for(i=0;i<N;i++)
        for(j=i;j<N;j++)
        if(a[j]>a[j+1])
        {
            p=a[j];
            a[j]=a[j+1];
            a[j+1]=p;
        }
    for(i=1;i<=N;i++)
        printf("a[%d]=%d\t",i,a[i-1]);
    return 0;
}

帮你改一下

#include<stdio.h>
#define N 10
int main()

 {
     int i,j,p;
     int a[N]={12,25,48,79,86,26,32,45,96,82};
     for(i=0;i<N;i++)
         for(j=0;j<N-i-1;j++)
         if(a[j]>a[j+1])
         {
             p=a[j];
             a[j]=a[j+1];
             a[j+1]=p;
         }
     for(i=0;i<N;i++)
         printf("a[%d]=%d\t",i,a[i]);
     printf("\n");
     return 0;

 }
