打印
"1 x 1 = 1
1 x 2 = 2
2x1 = 2
2x2 = 4
3x1 = 3
3x2 = 6"
等等。但我想做的事情就是这样，而不是让它们全部向下打印，我想把它放在块中，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。但显然它会更好看，如果它没有水平转到12或者你必须抓住控制台窗口底部的栏并拖动以查看其他时间稳定。我喜欢它，所以它在块1号线上变为5，然后在第2行块上变为6到10，最后一行变为10到12。
是的它是随机的，它只能达到12但这是一个练习，我只是将它改编成其他怪物。
我想我可能在for循环中只有一个以上的cout但是我发誓过去我曾经看过有人用一种聪明的方式来传递一个变量，这样它就会打印出一个星号块而不是假装去做。
期望的结果（使用符号更容易）：
" ***** ^^^^^ &&&&&
***** ^^^^^ &&&&&
***** ^^^^^ &&&&& "
截至目前的结果：
" *****
*****
*****
^^^^^
^^^^^
^^^^^
&&&&&
&&&&&
&&&&& "

要格式化列，请使用<iomanip>
设置要在输出操作中使用的字段宽度。
现在。
外面，迭代线。
在里面，迭代列。
#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;
}
}

只需删除TimeTable末尾的endl为内部＆＃34;为＆＃34; 并为拆分器添加另一个计数器：
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;
}
}
