我将如何水平打印更多块

How would I print more blocks horizontally?

本文关键字：打印 水平 何水平      更新时间：2023-10-16
#include <iostream>
using namespace std;
void TimesTable(int count)
{
    for (int j = 1; j < 13; j++)
    {
        cout << count << " x " << j << " = " << count*j << " " << endl;
    }
}
int main()
{
    for (int count = 1; count < 13; count++)
    {
        TimesTable(count);
        cout << endl;
    }
        system("Pause");
}

这打印 

"1 x 1 = 1
 1 x 2 = 2
 2x1 = 2
 2x2 = 4
 3x1 = 3
 3x2 = 6"

等等。但是我想做的是，与其让它们都向下打印成一条线，不如让它成块，所以，

 "1 x 1 = 1   2 x 1 = 2   3 x 1  = 3  4 x  1 = 4  5 x 1  = 5
  1 x 2  = 2  2 x 2 = 4   3 x 2 = 6   4 x 2 = 8   5 x 2 = 10"

等等。但显然，如果它没有水平转到 12，它看起来会更好，否则您必须抓住控制台窗口底部的栏并拖动以查看其他时间表。我希望它在块行 5 上达到 1，然后在块的第 2 行上变为 6 到 10，最后一行为 10 到 12。

是的，它只上升到 12 是随机的，但这是一个练习，我只是把它改编成其他怪物。

我想我可以在 for 循环中有多个 cout，但我发誓过去我见过有人用一种聪明的方式来传递变量，以便它并排打印一个星号块而不是假装这样做。

期望的结果(使用符号使其更容易(：

" ***** ^^^^^ &&&&&
  ***** ^^^^^ &&&&&
  ***** ^^^^^ &&&&& "

截至目前的结果：

" *****
  *****
  *****
  ^^^^^
  ^^^^^
  ^^^^^
  &&&&&
  &&&&&
  &&&&& "

要设置列的格式，请使用 std：：setw from <iomanip>

设置要用于输出操作的字段宽度。

现在。

在外面，迭代线条。

在内部，迭代列。

法典

#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
    int cols_per_line = 5;
    for (int line = 1; line < 13; line++)
    {
        for (int col = 1; col <= cols_per_line; col++)
        {
            cout << setw(2) << col << " x " << setw(2) << line << " = " << setw(3) << line*col << "   ";
        }
        cout << endl;
    }
}

输出

[root@rnrlabs ~]# ./a.out
 1 x  1 =   1    2 x  1 =   2    3 x  1 =   3    4 x  1 =   4    5 x  1 =   5
 1 x  2 =   2    2 x  2 =   4    3 x  2 =   6    4 x  2 =   8    5 x  2 =  10
 1 x  3 =   3    2 x  3 =   6    3 x  3 =   9    4 x  3 =  12    5 x  3 =  15
 1 x  4 =   4    2 x  4 =   8    3 x  4 =  12    4 x  4 =  16    5 x  4 =  20
 1 x  5 =   5    2 x  5 =  10    3 x  5 =  15    4 x  5 =  20    5 x  5 =  25
 1 x  6 =   6    2 x  6 =  12    3 x  6 =  18    4 x  6 =  24    5 x  6 =  30
 1 x  7 =   7    2 x  7 =  14    3 x  7 =  21    4 x  7 =  28    5 x  7 =  35
 1 x  8 =   8    2 x  8 =  16    3 x  8 =  24    4 x  8 =  32    5 x  8 =  40
 1 x  9 =   9    2 x  9 =  18    3 x  9 =  27    4 x  9 =  36    5 x  9 =  45
 1 x 10 =  10    2 x 10 =  20    3 x 10 =  30    4 x 10 =  40    5 x 10 =  50
 1 x 11 =  11    2 x 11 =  22    3 x 11 =  33    4 x 11 =  44    5 x 11 =  55
 1 x 12 =  12    2 x 12 =  24    3 x 12 =  36    4 x 12 =  48    5 x 12 =  60

只需删除时间表末尾的 endl 作为内部"for"并为拆分器添加另一个计数器说：

编辑：用计数更改j。

 int splitter = 0;
 for (int j = 1; j < 13; j++, splitter++)
 {
    cout << j << " x " << count  << " = " << count*j << "t";
    if (splitter == 5)
    {
       cout << endl;
       splitter=-1;
    }
 }
