请问Presentation Error是什么意思啊?以下是我的代码:
#include <stdio.h>
main()
{int a[100],i,j,n,m,t,l;
char str[100][51],s[51];
scanf("%d%d",&n,&m);
for(i=0;i<m;i++)
for(j=0;j<=n;j++)
scanf("%c",&str[i][j]);
for(i=0;i<m;i++)
for(a[i]=0,j=0;j<n;j++)
for(t=j+1;t<=n;t++)
if(str[i][j]>str[i][t]) a[i]++;
for(i=0;i<m-1;i++)
for(j=i+1;j<m;j++)
if(a[i]>a[j])
{l=a[i];
a[i]=a[j];
a[j]=l;
for(t=0;t<=n;t++)
{s[t]=str[i][t];
str[i][t]=str[j][t];
str[j][t]=s[t];
}
}
for(i=0;i<m;i++)
for(j=0;j<=n;j++)
printf("%c",str[i][j]);
}
提交后就出现了Presentation Error问题,请问各位高手这是什么问题,应该如何解决呢?
