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。
