c++基础问题，求解答！

Question

本来一个很简单的字符串拼接问题，因为题目要在2个字符串之间加逗号和空格，感觉很烦了，
我的方法代码看起来很丑，有没有更好方法，谢谢！

#include<iostream>
#include<string>
int main()
{
    using namespace std;
    string s1,s2,s3;
    char t[3]={',','\0'};
    cout << "Enter your first name: ";
    cin >> s1;
    cout << "Enter yor last name: ";
    cin >> s2;
    s3=s1+t;
    cout << "Here's the information in a single string: " << s3 << ' ' << s2 <<endl;
    return 0;
}

#include<iostream>
#include<cstring>
int main()
{
    using namespace std;
    const int n=20;
    char first[n],last[n];
    cout << "Enter your first name: ";
    cin.getline(first,n);
    cout << "Enter your last name: ";
    cin.getline(last,n);
    char t[2]={',','\0'};
    cout << "Here's the information in a single string: " << strcat(first,t) << ' ' << last <<endl;
    return 0;
}

你用的方法没什么问题吧，再简单可能就是用一个string放空格和逗号，然后两个string类型的变量再相加了
