/*排序*/

#include <iostream.h>

void fun(int *p);

void main()

{int a[20]={0};

int i;

cout<<"Please enter 20 numbers:"<<endl;

for(i=0;i<=19;i++)

cin>>a[i];

cout<<"The numbers you have entered are : "<<endl;

for(i=0;i<=19;i++)

cout<<a[i]<<endl;

fun(a);

cout<<"The munmbers are :"<<endl;

for(i=0;i<=19;i++)

cout<<a[i]<<endl;

}

void fun(int *P)

{int i,j,temp;

for(i=1;i<=19;i++)

{temp=p[i];

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

{if(p[i]<p[j]) {do {p[i]=p[i-1];i=i-1;}

while((i-1)>=j);

p[j]=temp;

break;}

}

}

}

#include <iostream.h>

}

void fun(int *P)

{int i,j,temp;

for(i=1;i<20;i++)

{

for (j=19;j>=i;j--)

{

if(P[j]<P[j-1])

{

temp = P[j-1];

P[j-1] = P[j];

P[j] = temp;

}

}

}

}

我用起泡法排序

你的错误么

1 void fun(int *P)，temp=p[i]; 变量名不匹配，将所有p改成P或者P改成p；
