同样两种语言(～￣▽￣)～

1.python代码（超简单！！！！！！）

a = input().split()
print(len(a))

2.c++代码

#include <bits/stdc++.h>
using namespace std;
int s;
int main()
{
    string a;
    while (cin >> a) s++;
    cout << s;
    return 0;
}

全网最简代码

#include <bits/stdc++.h>
using namespace std;
string s;
int ans;
int main()
{
    while(cin>>s) ans++;
    cout<<ans;
    return 0;
}

#include <iostream>
#include <string>
using namespace std;
int main()
{
	string a;
	getline(cin, a);
	int num = 1;
	for (int i = 0; i < a.size(); i++)
	{
		if (a[i] == ' ' && a[i + 1] != ' ')
		{
			num++;
		}
	}
	cout << num;
	return 0;
}

#include <iostream>
using namespace std;
int main()
{
    char s[100] = {0};
    int i, n = 0, x = 0;
    cin.getline(s, 100);
    for (i = 0; i < 100; i += 1)
    {
        if (s[i] == ' ')
        {
            x = 0;
        }
        else if (((x == 0) && (s[i] != ' ')) && (s[i] != 0))
        {
            x = 1;
            n += 1;
        }
    }
    cout << n << endl;
    return 0;
}//代码已AC
