《c程序设计语言》读书笔记--首次输入不能是空符；最多10个字符

#include <stdio.h>

#define Num 10

int main()
{
    int wor = 0;
    int arr[Num] = {0};
    int c,count = 0,i;
    int flag = 0;

    printf("Please input at most 10 words.\n");

    while((c = getchar()) != EOF)
    {
        if(c == '\n' ||c == ' ' || c == '\t')
            {
                if(flag == 0)
                {
                    arr[count] = wor;
                    count++;
                    wor = 0;
                    flag = 1;
                }
            }
        else
            {
                flag = 0;
                wor++;
            }
    }
    for(i = 0;i < count;i++)
        printf("%d ",arr[i]);

    return 0;
}

两个问题：首次输入不能是空符；最多10个字符。以后解决 。
