#include <stdio.h>
#define MAXS 15

void StringCount( char s[] );
void ReadString( char s[] ); /* 由裁判实现，略去不表 */

int main()
{
    char s[MAXS];

    ReadString(s);
    StringCount(s);

    return 0;
}
void StringCount(char s[])
{
    int i,letter=0,blank=0;
    for(i=0;i<15;i++)
    {
        if(char s[i]>97&&char s[i]<122)
        letter++;
        else if(char s[i]==" ")
        blank++
    }
}

还是有错啊
