最后做一个边框

问题描述

嘿伙计们试图像我之前的问题那样制作边框。很抱歉打造一个关于它的全新帖子。

无论如何..我在创建水平线时遇到了麻烦

这个角色只显示在右侧而不是整个东西。

Hey guys im trying to make a border just like on my previous question. Sorry for making a whole new thread about it.
Anyways.. im having trouble creating that horizontal line
the character is only showing on the right side but not the entire thing.

#include <stdio.h>
#include <windows.h>

HANDLE console = GetStdHandle(STD_OUTPUT_HANDLE);
COORD CursorPosition;

void gotoXY(int x, int y);
void border();


int main()
{int YEAR;

	border();


}

void gotoXY(int x, int y)
{
CursorPosition.X = x; // Locates column
CursorPosition.Y = y; // Locates Row
SetConsoleCursorPosition(console,CursorPosition); // Sets position for next thing to be printed
}

void border()
{
	int i;

	/*corners*/
	gotoXY(7, 3); printf(" %c", 201);
	gotoXY(90, 3);printf(" %c", 187);
	gotoXY(7, 30); printf(" %c", 200);
	gotoXY(90, 30); printf(" %c", 188);

	/*vertical lines*/
	for(i = 4; i < 30; i++)
	{
		gotoXY(7, i); printf(" %c", 186);
		gotoXY(90, i); printf(" %c", 186);
	}

	/*horizontal lines */
	for (i = 7; i < 90; i++)
	{
		gotoXY(i, 3); printf(" %c", 205);
		gotoXY(i, 30); printf(" %c", 205);
	}
}

我的尝试：

What I have tried:

/*horizontal lines */
	for (i = 7; i < 90; i++)
	{
		gotoXY(i, 3); printf(" %c", 205);
		gotoXY(i, 30); printf(" %c", 205);

推荐答案

引用：

水平部分根本没有显示。

我的意思是它确实只是在gotoXY（x，3/30）而不是整个事情。

the horizontal part isn't showing at all.
I mean it did but only on gotoXY(x, 3/30) and not the entire thing.

从 printf s中删除空格......：笑：

Remove the space from the printfs ... :laugh:

gotoXY(i, 3); printf(" %c", 205);
                      ^
                      |
gotoXY(i, 30); printf(" %c", 205);
                       ^
                       |

循环中的下一个会立即覆盖你写的字符！

The next one in the loop immediately overwrites the character you wrote!

引用：

我看到但对于其他像垂直的那些，我把空间放在它上面它仍然工作正常。我只是觉得你总是要放一个空格，如果它的％c

I see but for the other ones like the vertical ones, i put space on it and it still worked fine. I just thought you always have to put a space if its %c

不，这个空格是一个可打印的角色。

当您使用它来写水平线时，它会覆盖：

Nope, the space is a printable character.
When you use it to write a horizontal line it overwrites:

0123456789  (column number)
 |          (after gotoXY(0, 1); printf)
  |         (after gotoXY(1, 1); printf)
   !        (after gotoXY(2, 1); printf)
...

引用：

现在我遇到了程序问题。

正如你可以看到除了if / else语句之外的所有东西都有gotoXY。 />
当我插入gotoXY时，我会收到错误，例如Else is no previous if if

Now i'm having trouble with the program.
As you can see everything has gotoXY besides the one on the if/else statements.
when i insert gotoXY, i get errors such as "Else has no previous if"

那是因为你很懒！ ：笑：

养成一直使用大括号的习惯：即使是单行如果或 else 声明：

That's because you are being lazy! :laugh:
Get into the habit of always using curly brackets whenever you possibly can: even for single line if or else statements:

if (a == b)
   {
   statement;
   }
else
   {
   statement;
   }

如果你不这样做，那么你最终会这样做：

If you don't, then you end up doing this:

if (a == b)
   gotoXY(10,2);
   printf("Product:%d", base);
else
   statement;

哪个 看起来 是的，但编译器正确地将其视为：

Which looks right, but the compiler rightly sees it as this:

if (a == b)
   {
   gotoXY(10,2);
   }
printf("Product:%d", base);
else
   statement;

并抱怨它无法与 else匹配到如果

它会为你节省大量时间并且让人头疼！

And complains that it can't match the else to an if
It'll save you a lot of time and head scratching!
