#include <iostream>

#include "string.h"

using namespace std;

int main()
{
	char string1[81];

	cout << "请输入一行字符：";

	cout << endl;

	gets(string1);

	int i = 0, num = 0, m = 0, j = 0;
	
	while(string1[i] == ' ' || string1[i] == ',' || string1[i] == '.' || string1[i] == ';' || string1[i] == '?' || string1[i] == '!')
	{
		i = i + 1;
	}
	
	m = i;
	
	for (i = m; string1[i] != '\0'; ++i)
	{
		
		if (string1[i] == ' ' || string1[i] == ',' || string1[i] == '.' || string1[i] == ';' || string1[i] == '?' || string1[i] == '!')
		{
			num++;
			
			while(string1[i+1] == ' ' || string1[i] == ',' || string1[i] == '.' || string1[i] == ';' || string1[i] == '?' || string1[i] == '!')
			{
				i = i + 1;
			}
		}
		
	}
	
	cout << "There are " << num << " words in the line.";
	
	cout << endl;
	
	return 0;
}

运行结果：

经验积累：
1.我学会了用gets(string1);
上机感言：
字符数组在一些情况下很好用。
