我是初学者~

输入一句话~结果是输出这句话有多少个单词~这句话是随机的~

指导一下~

#include <iostream>

#include <string>

using namespace std;

int main()

{

string words;

unsigned count = 0;

cout << "Enter a line of words:\n";

while(cin >> words && cin.peek() != '\n')

{

++count;

}

cout << "The line you had inputed has " << count + 1 << " words." << endl;

}
