如何打印上线帮助 [英] how to print an overline pls help

问题描述

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


const int iRow = 9;
const int iColumn =9;

void PrintArray(int iNum[][iColumn], int iR, int iC){
    for(int i=0;i<iR;i++){

        cout<< "\n";
        cout<<" ___  ___  ___  ___  ___  ___  ___  ___  ___ ";
        cout<< "\n";
        for(int j=0; j<iC; j++){
            cout<< "[ "<<iNum[i][j]<<" ]";
            }
        cout<<"  ";
        cout<< "\n";
    }

}
int main(){

     int iSud[iRow][iColumn] = { { 4, 5, 2, 3, 9, 1, 8, 7, 6 },
                                { 3, 1, 8, 6, 7, 5, 2, 9, 4 },
                                { 6, 7, 9, 4, 2, 8, 3, 1, 5 },
                                { 8, 3, 1, 5, 6, 4, 7, 2, 9 },
                                { 2, 4, 5, 9, 8, 7, 1, 6, 3 },
                                { 9, 6, 7, 2, 1, 3, 5, 4, 8 },
                                { 7, 9, 6, 8, 5, 2, 4, 3, 1 },
                                { 1, 8, 3, 7, 4, 9, 6, 5, 2 },
                                { 5, 2, 4, 1, 3, 6, 9, 8, 7 }
                                };


    PrintArray(iSud,iRow,iColumn);
}

如果你运行代码，它几乎看起来像数字在一个盒子里，除了有一个开口底部。



如何打印上划线符号/字符。我需要它来完成打印输出

谢谢

if you run the code it will almost look like the numbers are in a box except there is an opening at the bottom.

how can I print an overline symbol/character. I need it to complete the printed output
thanks

推荐答案

简单解决方案：在整个循环之后插入您的打印代码。

复杂的解决方案：再循环一次打印代码。

Easy solution: insert your print code AFTER the whole loop.
Complex solution: loop one more time for print code.

void PrintArray(int iNum[][iColumn], int iR, int iC){
    for(int i=0;i<=iR;i++){
 
        cout<< "\n";
        cout<<" ___  ___  ___  ___  ___  ___  ___  ___  ___ ";
        cout<< "\n";
        //exit loop after close print
        if( i == (iR-1) ) break;
        for(int j=0; j<ic;>            cout<< "[ "<<iNum[i][j]<<" ]";
            }
        cout<<"  ";
        cout<< "\n";
    }
}

上划线字符的 UNICODE 字符为 U + 203E [ ^ ]。

以下丑陋的代码在我的系统上起作用（ Linux ， g ++ 4.7.3 ）。

The UNICODE character for the overline character is U+203E[^].
The following ugly code does the trick on my system (Linux with g++ 4.7.3).

void PrintArray(int iNum[][iColumn], int iR, int iC){
    for(int i=0;i<iR;i++){

        cout<< "\n";
        cout<<" ___  ___  ___  ___  ___  ___  ___  ___  ___ ";
        cout<< "\n";
        for(int j=0; j<iC; j++){
            cout<< "[ "<<iNum[i][j]<<" ]";
            }
        cout<<"  ";
        cout<< "\n";
        for (int i=0; i<9; ++i)
          cout << " \u203E\u203E\u203E ";
        cout << endl;
    }

}
