C++ 用C+打印盒图案+；

我正在编写一个程序来打印两个方框，如下图所示：

我尝试了下面的程序，但它没有给出预期的输出

#include<iostream>

using namespace std;

int main()
{
    // Considering each box as a separate one
    for(int i = 1; i <= 2; i++)
    {           
    cout << "+---+ " << endl;
    cout << "|  " << i << "| " << endl;
    cout << "|   | " << endl;
    cout << "|   | " << endl;
    cout << "+---+ ";
    }

    return 0;
}

请帮我找到我丢失的东西。

任何帮助或提示都将被高度赞赏。

不能将每个框视为单独的框，因为您将它们作为字符打印到一行一行的终端中。您必须先打印所有框的顶部，然后打印所有框的下一行，以此类推

如果要打印的框数可变，这将是解决方案：

int main() {
    using namespace std;
    unsigned numberOfBoxes = 10;

    for (unsigned i = 0; i < numberOfBoxes; ++i)
        cout << "+---+" << (i == numberOfBoxes - 1 ? "\n" : " ");
    for (unsigned i = 0; i < numberOfBoxes; ++i)
        cout << "|  " << i << "|" << (i == numberOfBoxes - 1 ? "\n" : " ");
    for (unsigned i = 0; i < numberOfBoxes; ++i)
        cout << "|   |" << (i == numberOfBoxes - 1 ? "\n" : " ");
    for (unsigned i = 0; i < numberOfBoxes; ++i)
        cout << "|   |" << (i == numberOfBoxes - 1 ? "\n" : " ");
    for (unsigned i = 0; i < numberOfBoxes; ++i)
        cout << "+---+ ";
}

intmain（）{
使用名称空间std；
无符号numberofbox=10；
for（无符号i=0；icout如果您逻辑地跟踪for循环，您将看到如何一次打印一个框，堆叠在另一个框上

您需要确保在同一行上打印所有框的顶部，然后移动到所有框的主体，依此类推，直到所有框都“并行”打印

为此，您可以在其自己的for循环中打印每一行。例如：

#include<iostream>

using namespace std;

int main()
{
    for(int i = 1; i <= 2; i++) cout << "+---+ ";
    cout << endl;
    for(int i = 1; i <= 2; i++) cout << "|  " << i << "| ";
    cout << endl;
    for(int i = 1; i <= 2; i++) cout << "|   | ";
    cout << endl;
    for(int i = 1; i <= 2; i++) cout << "|   | ";
    cout << endl;
    for(int i = 1; i <= 2; i++) cout << "+---+ ";

    return 0;
}

int main（）
{
对于（inti=1；i对Maros答案的扩展：

如果以表格或矩阵形式打印时需要多行和多列：

int main() {
    using namespace std;
    unsigned numberOfColumns = 2, numberOfRows = 2;

    for (unsigned int i = 1; i <= numberOfRows; ++i) {
        for (unsigned j = 1; j <= numberOfColumns; ++j)
            cout << "+---+" << (j == numberOfColumns ? "\n" : " ");
        for (unsigned j = 1; j <= numberOfColumns; ++j)
            cout << "|  " << j + (numberOfColumns *(i-1)) << "|" << (j == numberOfColumns ? "\n" : " ");
        for (unsigned j = 1; j <= numberOfColumns; ++j)
            cout << "|   |" << (j == numberOfColumns ? "\n" : " ");
        for (unsigned j = 1; j <= numberOfColumns; ++j)
            cout << "|   |" << (j == numberOfColumns ? "\n" : " ");
        for (unsigned j = 1; j <= numberOfColumns; ++j)
            cout << "+---+ ";
        cout << endl;
    }   
    return 0;
}

intmain（）{

无符号numberOfColumns=2，numberOfRows=2；
对于（unsigned int i=1；i@downvoter），我尽了最大努力，但找不到解决方案。请告诉我downvoting的原因。我建议您发布您得到的内容。另外请注意，您的方框打印在同一行上（例如，第一行是
+--++--+
，都在一行中。如果你想使用普通的
std:：cout
，你将找不到一个单独打印框的解决方案。试着打印两个框的第一行，继续打印两个框的第二行，以此类推…@wolff，我希望我可以按行打印，但我不能，因为每一行都有一行。）x必须单独处理。@BhawandeepSingla否决投票的原因可能是您没有显示当前尝试的结果，也没有进一步阐述您的预期。
