Question

所以输出应该是这样的：

        This is a Heading blah
        ---------------------
        1st - First
        2nd - Second
        3rd - Third

我将在下面发布我的代码，但在你判断之前请注意这是我第二天学习C ++（任何编程语言）。我可能看起来像个白痴，但感谢先进的任何帮助。

char place = '1';                                   
string firstPlace = "First";            

char place = '1';                                   
string secondPlace = "Second";                

char place = '1';                                   
string thirdPlace = "Third";

cout << "This is a Heading blah" << endl;
cout << "---------------------" << endl;
cout << "1st - " << firstPlace;
cout <<'\n';
cout << "2nd - " << secondPlace;
cout <<'\n';
cout << "1st - " << thirdPlace;
cout <<'\n';

首先，您需要包含std函数的头文件：

#include <iostream> // cout
#include <string> // string
using namespace std; // or std::cout

和地点被宣布超过1次：

char place = '1';                                   
string firstPlace = "First";

所以，代码应该是：

#include <iostream>
#include <string>
using namespace std;

int main(int argc, char const *argv[])
{
    char place = '1';  
    string firstPlace = "First";  
    string secondPlace = "Second";                


    string thirdPlace = "Third";              

    cout << "This is a Heading blah" << endl;
    cout << "---------------------" << endl;

    cout << "1st - " << firstPlace;

    cout <<'\n';

    cout << "2nd - " << secondPlace;

    cout <<'\n';

    cout << "1st - " << thirdPlace;

    cout <<'\n';
    return 0;
}

我是C ++的新手，需要知道我做错了什么
