Question

大家帮我看看我的代码为什么运行不了？

#include <stdio.h>
#include <iostream>
#include <string.h>

using namespace std;
int main ()
{
int n=0,c[1001][1001],a[1001],b[1001];
while(scanf("%d",&n)!=EOF)
{
int i=0,j=0,t=0;
for(i=0;i<n;i++)
{
scanf("%d",&a[i]);
b[i]=a[i];
}
memset(c,0,sizeof(c));
for(i=0;i<n;i++)
for(j=i;j<n;i++)
if(b[i]>b[j])
{
t=b[i];
b[i]=b[j];
b[j]=t;
}
for(i=1;i<=n;i++){c[i][0]=0;c[0][i]=0;}
for(i=1;i<=n;i++)
for(j=1;j<=n;j++)
{
if(a[i-1]==b[j-1]){c[i][j]=c[i-1][j-1]+1;}
else if(c[i-1][j]>c[i][j-1]){c[i][j]=c[i-1][j];}
else {c[i][j]=c[i][j-1];}
}
printf("%d\n",c[n-1][n-1]);
}
return 0;
}

#include <stdio.h>
#include <iostream>
#include <string.h>

using namespace std;
int n=0,c[1001][1001],a[1001],b[1001]; /* 内存太大 */
int main ()
{
while(scanf("%d",&n)!=EOF)
{
int i=0,j=0,t=0;
for(i=0;i<n;i++)
{
scanf("%d",&a[i]);
b[i]=a[i];
}
memset(c,0,sizeof(c));
for(i=0;i<n;i++)
for(j=i;j<n;j++) /* j++ */
if(b[i]>b[j])
{
t=b[i];
b[i]=b[j];
b[j]=t;
}
for(i=1;i<=n;i++){c[i][0]=0;c[0][i]=0;}
for(i=1;i<=n;i++)
for(j=1;j<=n;j++)
{
if(a[i-1]==b[j-1]){c[i][j]=c[i-1][j-1]+1;}
else if(c[i-1][j]>c[i][j-1]){c[i][j]=c[i-1][j];}
else {c[i][j]=c[i][j-1];}
}
printf("%d\n",c[n-1][n-1]);
}
return 0;
}
