统计一行字符的单词个数，单词间暂时约定用空格来分析

//统计一行字符的单词个数
#include<stdio.h>
#include<string.h>
#include<stdlib.h>

int Is_Separate(char ch)
{
    char strSeparate[] = {',', ' ', '?', '.'};
    for (int i = 0; i < strlen(strSeparate); i++)
    {
        if (ch == strSeparate[i])
        {
            return 1;
        }
    }
    return 0;
}

int main()
{
    char strCharacter[] = " how are you? I am fine. what is your name? my name is xiao! ";

    int nSeparate = 1;
    int nWorld = 0;
    int nCount = 0;

    for (int i = 0; i < strlen(strCharacter); i++)
    {
        if (nSeparate && !Is_Separate(strCharacter[i]))
        {
            nSeparate = 0;
            nWorld = 1;
            nCount++;
        }
        if (nWorld && Is_Separate(strCharacter[i]))
        {
            nWorld = 0;
            nSeparate = 1;
        }
    }

    printf("%d\r\n", nCount);

    system("pause");
    return 0;
}
