简单！

只要判断一下 n 的值就行了！

#include <bits/stdc++.h>
using namespace std;
long long n;
int main(){
	cin >> n;
	if(n == 1 || n == 0) cout << "Today, I ate " << n << " apple.";
	else cout << "Today, I ate " << n << " apples.";
	return 0;
}

#include<bits/stdc++.h> #include using namespace std; int main() { int x; cin>>x; if(x0) { cout<<"Today, I ate 0 apple."; } if(x1) { cout<<"Today, I ate 1 apple."; } if(x>1) { cout<<"Today, I ate "<<x<<" apples."; } return 0; } //自己换行，我已经尽力了！！！
