输出答案是点样子??贴出来看看.

void sort(char *name[],int n){
char *pt;
int i,j;
for (i=0;i<=n;i++){
for (j=i;j<=n;j++)
if strcmp(name[i],name[j])>0){
*pt=name[i];
name[i]=name[j];
name[j]=*pt;
}
}
}

改前:
AMERICA
AUSTRALIA
CHINA
FRANCE
GERMAN
Press any key to continue

改后:
(null)
AMERICA
AUSTRALIA
FRANCE
GERMAN
Press any key to continue

你给的代码不行哈

for(i=0;i<n-1;i++)
{
k=i;
for(j=i+1;j<n;j++)
if(strcmp(name[k],name[j])>0) k=j;
if(k!=i)
{
pt=name[i];
name[i]=name[k];
name[k]=pt; //k指示的是要正确和name[i]相交换的下标的位置，但j每次都会到循环的结束,两者肯定不能混用了
}
}
