创建表头

Creating Table headers?

本文关键字:表头 创建      更新时间:2023-10-16

好的,在这个程序中,我需要根据用户输入制作一个表格。问题是我无法弄清楚如何使表标题与显示的信息正确对齐。表标题不会从以下位置排列 例如,如果用户输入玩家 1 的迈克尔和玩家 2 的迈克尔乔丹。任何允许标题与显示的输入正确对齐的建议,无论字符长度如何,都将不胜感激,谢谢。

这是我的代码:

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

//struct of Basketball Player info
struct BasketballPlayerInfo
{
    string name; //player name
    int playerNum, //player number
        pointsScored; //points scored
};
int main()
{
    int index, //loop count
        total = 0; //hold total points
    const int numPlayers = 5; //nuymber of players
    BasketballPlayerInfo players[numPlayers]; //Array of players
    //ask user for Basketball Player Info
    cout << "Enter the name, number, and points scored for each of the 5 players.n";
    for (index = 0; index < numPlayers; index++)
    {
        //collect player name
        cout << " " << endl;
        cout << "Enter the name of player # " << (index + 1);
        cout << ": ";
        //input validation
        if(!(getline(cin, players[index].name)))
        {
            cout << "Player Name must be alphabetical characters only!n";
            cout << "Program terminating please start over." << endl;
            system("pause");
            exit(0);
        }
        //getline(cin, players[index].name);
        //collect players number
        cout << "Enter the number of player # " << (index + 1);
        cout << ": ";
        //input validation
        if(!(cin >> players[index].playerNum))
        {
            cout << "Player Name must be numeric characters only!n";
            cout << "Program terminating please start over." << endl;
            system("pause");
            exit(0);
        }
        //collect points scored
        cout << "Enter points scored for player # " << (index + 1);
        cout << ": ";
        //input validation
        if(!(cin >> players[index].pointsScored))
        {
            cout << "Player Name must be numeric characters only!n";
            cout << "Program terminating please start over." << endl;
            system("pause");
            exit(0);
        }
        cin.ignore();
    }
    //display
    cout << "n";
    cout << "Here is the information for each player: n";
    cout << fixed << showpoint << setprecision(2);
    cout << "n";
    cout << "          tNametNumbertPointsn";
    cout << "------------------------------------------------" << endl;
    for(index = 0; index < numPlayers; index++)
    {
        cout << "Player # " << (index + 1);
        cout << ": t" << players[index].name << "t" << players[index].playerNum << "t" << players[index].pointsScored << endl;
        cout << "------------------------------------------------" << endl;
    }
    //display total points scored by all players
    for(index = 0; index < numPlayers; index++)
    {
        //hold total
        total += players[index].pointsScored;
    }
    cout << "Total Points scored are: " << total << endl;
 system("pause");
return 0;
}

您可以使用#include <iomanip>下的setw io操纵器。

cout << setw(20) << "Column1"
     << setw(20) << "Column2"
     << setw(8) << "Column3";

或者您可以使用提升库

使用 Boost.Format

cout << format("%-20s %-20s %-8sn")  % "Column1" % "Column2" % "Column3";

看看setw和setfill函数。您可以使用它们为列分配最小宽度,这将使输出格式比选项卡更清晰。
