#include<stdio.h>
main()
{int i,N;
char ch;
scanf("%d",&N);
for(i=1;i<=N;i++){
ch=getchar();
if(ch>='A'&&ch<='Z')
printf("perfect\n");
else if(ch>='a'&&ch<='z')
printf("good\n");
else(ch>='0'&&ch<='9');
printf("nice\n");
other:
printf("ok");
}

Answer 1

other：错了，换成else就行了，上边else换成else if

else if(ch>='0'&&ch<='9');
printf("nice\n");
else
printf("ok");
