Question

#include<stdio.h>
#include<string.h>
int main()
{
char s[80];
int a=0,b=0,c=0,d=0,g=0;
gets(s);
while(s[g]!='\0')
{
if(s[g]<='Z'&&s[g]>='A'||s[g]<='z'&&s[g]>='a')
{
b++;
}
else if(s[g]>='0'&&s[g]<='9')
{
a++;
}
else if(s[g]==' ')
{
c++;
}
else
{
d++;
}
g++;
}
printf("%s\n",s);
printf("%d\n",strlen(s));
printf("数字有%d个英文字母有%d个空格有%d个其他字符有%d个\n",a,b,c,d);
return 0;
