#include"stdio.h"

char str[100],*p=str;
int number_of_letter,number_of_digit,number_of_pace,number_of_other;
number_of_letter=number_of_digit=number_of_pace=number_of_other=0;
printf("please input a line letter:\n");
gets(str);
printf("\n\nIN:\n ");
puts(str);
printf("have:\n");
for(;*p!='\0';p++)
{
if(*p==' ')number_of_pace++;
else
if(*p>='0'&&*p<='9')number_of_digit++;
else
if((*p>='a'&&*p<='z')||(*p>='A'&&*p<='Z'))
number_of_letter++;
else number_of_other++;
}
printf(" %-4d space;\n",number_of_pace);
printf(" %-4d letter;\n",number_of_letter);
printf(" %-4d digit;\n",number_of_digit);
printf(" %-4d other;\n",number_of_other);
printf("\n\nTHAT ALL!!!!!!\n\n");
