问题描述
请输入任意5位数字：56789
和输出是
5678 9
567 89
56 789
5 6789
如何编写这些程序......
我的想法是这样的...
#include< stdio.h>
void main（）
{
int num;
float num1，num2，num3，num4;
float r1，r2，r3，r4;
printf（请输入任意5位数字：）;
scanf（"％d"，& num）;
num1 = num / 10;
num2 = num / 100;
num3 = num / 1000;
num4 = num / 10000;
r1 = num％10;
r2 = num％100;
r3 = num％1000;
r4 = num％10000;
printf（" \ n％。0f％。0f"，num1，r1）;
printf（ \ n％.0f％。0f，num2，r2）;
printf（" \ n％.0f％。0f"，num3，r3）;
printf（" \ n％.0f％。0f"，num4，r4）;
}

怎么样写那些节目......
我的想法是这样的...
#include< stdio.h>
void main（）
main返回一个int。请参阅 www.c-faq.com ，问题1.25b。
< blockquote class =post_quotes>
{
int num;
float num1，num2，num3，num4;
float r1 ，r2，r3，r4;
printf（请输入任意5位数字：）;
scanf（"％d" ，试验＃）;

保证适合int的最大值是32767.声明
num作为一个长的（你需要使用％ld而不是％d）。
顺便说一下，绝对不需要使用浮点
$ b $在这里，整数会这样做，或者更好的仍然认为输入为
a字符串，就像你在另一个帖子中被告知的那样。
这样做：
从stdin读取6个字符;
如果前5个字符是数字，第6个字符是空格，
输入正常;正如你在另一个线程中被告知的那样处理它;
别做一些明智的事情。请注意，如果
失败，则scanf不会触及num（例如，没有数字数据，但字母或
标点符号或其他），在这种情况下，num保持未初始化状态。不要
使用scanf（），除非没有更好的选择。提示：总有
是更好的选择。

如何使用％ld ??因为我是一个新手....还有很多编码，
我以前从未见过
please key in any 5 digits number : 56789
and the ouput is
5678 9
567 89
56 789
5 6789
how to write those program......
my idea is like this...
#include <stdio.h>
void main()
{
int num;
float num1,num2,num3,num4;
float r1,r2,r3,r4;
printf("please key in any 5 digit number:");
scanf("%d",&num);
num1=num/10;
num2=num/100;
num3=num/1000;
num4=num/10000 ;
r1=num%10;
r2=num%100 ;
r3=num%1000 ;
r4=num%10000 ;
printf("\n %.0f %.0f",num1,r1);
printf(" \n %.0f %.0f",num2,r2);
printf(" \n %.0f %.0f",num3,r3);
printf(" \n %.0f %.0f",num4,r4);
}

the problem occur when i entered nnumber 56789.It output become
rubbish when i put 56789...
but if i key in 12345 the program excute nicely.....
anyone can tell what wrong with my coding...
and i really appriciate if someone can make it more efficient....

anyone can tell what wrong with my coding...The maximum value guaranteed to fit in an int is 32767. Declare
num as a long (you''ll need to use "%ld" instead of "%d").
By the way, there is absolutely no need to use floating point
here, integers would do it, or better still consider the input as
a string as you were told in the other thread.
Do like this:
read 6 characters from stdin;
if the first 5 characters are digits and the sixth is whitespace,
the input is ok; process it as you were told in the other thread;
else do something sensible. Note that scanf doesn''t touch num if
it fails (e.g. there are no numeric data but letters or
punctuation or else), in which case num stays uninitialized. Don''t
use scanf() unless there is no better choice. Hint: there always
is a better choice.
