哪里出错了？ [英] Where is the mistake?

问题描述

希望有人可以帮我解决这个问题。

案例1正在使用一个数字条目完美地工作。

案例2是我尝试2时的问题数字输入。

案例1.

#include< stdio.h>

int main（）

{

int a，i;


for（i = 1; i< = 3; i ++）

{

scanf（"％d"，& a）;

printf（"％d \ n"，a）;

}

返回0;

}

/ *结果

5

5

15

15

234

234

按任意键继续

* /

结果显示，我输入5，计算机打印5，

输入15，计算机打印15,234，打印234。这个问题。


当我处理2个数字a和b时出现问题。


案例2

#include< stdio.h>

int main（）

{

int a，b，i;


for（i = 1; i< = 3; i ++）

{

scanf（"％d，％d"& a，& b）;

printf（"％d，％d \ n"， a，b）;

}

返回0;

}

/ *结果

1 2

1，-858993460

2，-858993460

3 4

3， - 858993460

按任意键继续

* /


从上面的结果可以看出，当我输入1 2 ，我得到了奇怪的结果。我怀疑电脑正在打印空间。和输入密钥。

如何克服这个问题？


谢谢

Hope someone can help me to overcome this problem.
Case 1 is working perfectly working with one number entry.
Case 2 is the problem when I tried with 2 numbers entry.
Case 1.
#include <stdio.h>
int main ()
{
int a,i;

for (i=1;i<=3;i++)
{
scanf ("%d",&a);
printf ("%d\n",a);
}
return 0;
}
/* Result
5
5
15
15
234
234
Press any key to continue
*/
As the result shows, I enter 5 and computer prints 5,
enter 15 and computer prints 15 , 234 and prints 234. No problem with this.

The problem comes when I deal with 2 numbers, a and b.

Case 2
#include <stdio.h>
int main ()
{
int a,b,i;

for (i=1;i<=3;i++)
{
scanf ("%d,%d",&a,&b);
printf ("%d,%d\n",a,b);
}
return 0;
}
/* Result
1 2
1,-858993460
2,-858993460
3 4
3,-858993460
Press any key to continue
*/

As you can see from the above result, when I enter 1 2, I get weird result. I suspect the computer is printing "space" and "enter key".
How do I overcome this problem?

Thanks
Khoon.

不要输入1 2.这不是你编程的。相反，输入1,2

（即％d，％d）。


如果您打算输入1 2 do ％d％d。

Don''t enter 1 2. That''s not what you programmed. Instead, enter 1,2
(which is "%d,%d").

If instead you intend to enter 1 2 do "%d %d".
