短小精悍 #include <bits/stdc++.h> using namespace std; int main() { char n; int i=1,t=0; while(cin>>n) { if(n!=' ') { cout<<n; t++; } } cout<<"\n"<<t; return 0; }

#include<bits/stdc++.h>
using namespace std;
int main()
{

string a;
int n = 0;
while (cin >> a)
{
n = n + a.size();
for (int b = 0; b <= a.size() - 1; b++)
{

cout << a[b];

}

}
cout << endl;
cout << n;


}

注意有空格的字符串的读取要用getline 以及string的遍历可以用auto（需C++11）

#include <bits/stdc++.h>
using namespace std;

int main()
{
	int cnt = 0;
	string s;
	getline(cin,s);
	for(auto x:s)
	{
		if(x!=' ') cout << x;
		else cnt++;
	}
	cout << endl << s.length()-cnt;
	return 0;
}
