#include <iostream>
#include <string>
using namespace std;
int main(){
	int x;
	cin>>x;
	string s[]={"one","two","three","four","five","six","seven","eight","nine"};
	cout<<"My cat is "<<s[x-1]<<" years old."<<endl;
	return 0;
}

很简单易懂吧

#include <iostream>
#include <string>
using namespace std;
int main(){
	int	x;
	cin >> x;
    string s[]={"","one","two","three","four","five","six","seven","eight","nine"};
    cout<< "my cat is " <<s[x]<<" years old"<<endl;
    return 0;
}

运行是从0开始要给它个空白文件

#include #include using namespace std; int main() { int x; cin>>x; string shu[]={"one","two","three","four","five","six","seven","eight","nine"}; cout<<"My cat is "<<shu[x-1]<<" years old."<< endl; return 0; }

1是单数，第一问应该用year，不应该用years

#include using namespace std;

int main() { int x; cin>>x; string words[]={"","one","two","three","four","five"<"six","seven","eight","nine"}; cout<<"my cat is"<<words[x]<<"years old"; return 0; }

using namespace std;
int main(){
    int a;
    cin>>a;
    cout<<"My cat is ";
    if(a==1){
    	cout<<"one";
	}
	else if(a==2){
    	cout<<"two";
	}
    else if(a==3){
    	cout<<"three";
	}
	else if(a==4){
    	cout<<"four";
	}
	else if(a==5){
    	cout<<"five";
	}
	else if(a==6){
    	cout<<"six";
	}
	else if(a==7){
    	cout<<"seven";
	}
	else if(a==8){
    	cout<<"eight";
	}
	else if(a==9){
    	cout<<"nine";
	}
	else if(a==10){
    	cout<<"ten";
	}
	cout<<" years old.";
	
     return 0;
}
