Book Abstract

第3章“各种”趣味整数
整数通常是程序设计语言的一种基础形态，例如Java及C编程语言的int类型。整数问题是实际应用中遇到的一类问题。整型数据从所占内存大小可分为基本整型（int）、长整型（longint）和短整型（shortint），根据数据满足的某些性质又可将其分为“完全数”、“水仙花数”、“亲密数”等。整数问题中经常用到的是对数据的拆分、组合，初学者一定要从实例中总结方法并掌握。本章主要通过对各类整数问题的算法进行讲解，以培养读者的编程思维方式与编程技巧。本章主要内容如下：
完数；
亲密数；
自守数；
回文数；
水仙花数；
阿姆斯特朗数；
高次方数；
黑洞数；
沟股数；
不重复的3位数。
3.1完数
1．问题描述
求某一范围内完数的个数。
如果一个数等于它的因子之和，则称该数为“完数”（或“完全数”）。例如，6的因子为1，2，3，而6=1+2+3，因此6是“完数”。
2．问题分析
根据完数的定义，解决本题的关键是计算出所选取的整数i（i的取值范围不固定）的因子（因子就是所有可以整除这个数的数），将各因子累加到变量s（记录所有因子之和），若s等于i，则可确认i为完数，反之则不是完数。
3．算法设计
对于这类求某一范围（由于本题范围不固定，在编程过程中采用键盘输入的方式）内C语言趣味编程100例
·70·
满足条件的数时，一般采用遍历的方式，对给定范围内的数值一个一个地去判断是否满足条件，这一过程可利用循环来实现。
本题的关键是求出选取数值i的因子，即从1到i-1范围内能整除i的数，看某一个数j是不是i的因子，可利用语句if(i%j==0)进行判断，求某一个数的所有因子，需要在1到i-1范围内进行遍历，同样采用循环实现。因此，本题从整体上看可利用两层循环来实现。外层循环控制该数的范围2～n；内层循环j控制除数的范围为1～i，通过i对j取余，是否等于0，找到该数的各个因子，程序段如下：
for(i=2;i<=n;i++)
{
…
for(j=1;j {
…
}
if(s==i)
输出当前i是完数
}
对于某个选定的数，将求得的各因子累加到变量s（累加过程中用到s的初值，所以s初值为0）之后，s的值发生改变，若直接将下一个选定数的因子加到s上，得到的值并非所求（此时s的初值不是0而是上一个选定数的因子之和）。因此每次判断下一个选定数之前，必须将变量s的值重新置为0，编程过程中一定要注意变量s重新置0的位置，语句放的位置不正确得到的结果也不是正确结果。
注意：C语言中的整数问题，经常涉及判断两数是否相等或某变量（或表达式）是否满足某一条件的情况，对于这类问题，初学者经常会存在对赋值符号“=”与等于号“==”混淆的问题。
赋值符号“=”：基本的赋值运算符是“=”。它的优先级别低于其他的运算符，所以对该运算符往往最后读取。它的作用是将一个表达式的值赋给一个（左值）变量，左值必须能够被修改，不能是常量。如while(i=10)……此表达式的作用是将右值“10”赋给左值i，每次判断i的值都为10，所以表达式的值为非0，即判定条件为真，导致程序进入死循环。等于号“==”：是关系运算符的一种，结果只有两种“真”或“假”。作用是用来判断等号“==”两边参与运算的值是否相等，若相等，则返回“真”，否则返回“假”。如while(i==10)……这里的表达式作用是判断变量i的值是否等于10，若相等，则表达式的值为真，如不相等则为假，当表达式为真时，程序继续执行循环体语句，否则结束循环。4．确定程序框架
程序流程图如图3.1所示。
5．完整程序
#include
main()
{
inti,j,s,n;/*变量i控制选定数范围，j控制除数范围，s记录累加因子之和*/
printf("请输入所选范围上限：");
scanf("%d",&n);/*n的值由键盘输入*/
第3章“各种”趣味整数
·71·
for(i=2;i<=n;i++)
{
s=0;/*保证每次循环时s的初值为0*/
for(j=1;j {
if(i%j==0)/*判断j是否为i的因子*/
s+=j;
}
if(s==i)/*判断因子之和是否和原数相等*/
printf("It'saperfectnumber:%d.\n",i);
}
}
