It is an inescapable fact that to most people there comes a time when failing powers of mind or body made it impossible for them to manage their daily lives without some sort of help, and despite the weakened sense of family solidarity, this help comes in many cases from children, other relatives, or occasionally friends. When an old person or old couple gives up an independent home and becomes part of another household it does not mean that all the problems of old age are automatically solved; the problems are different, not so pressing perhaps, and their solution lies more with the younger relatives than with the older people themselves. Caring for the aged requires skill as well as goodwill. Much advice is now available for those caring for young children and babies, and there are numerous books to help mothers in bringing up their families, but as far as I know little has been written about the day-to-day care of old people. Fortunately the first essentials, sympathy and affection, are very often to be found, and will carry relatives, friends and old people a long way, but not the whole way; without these two virtues the work of caring for the old can be onerous (繁重的) and unrewarding. Probably the first thing for anyone to learn who has old people to care for is the need to allow them the freedom of action, to realize that their personality is still individual and that social significance is essential to happiness. It is all too easy to take the attitude that the old are past doing anything and to encourage resting and doing nothing. This is mistaken kindness, though it may be an easy way of satisfying the conscience compared with the more exacting way of continual encouragement to be active, to go out, to find worthwhile occupation. The latter course, 10 however, is much more likely to promote happiness.

第3题：
请编写两个函数int sum_of_powers(int k，int n)，powers(int m，int n)，求1～6的k次方的和,sum_of_powers中参数k和n分别表示k次方和所求数列中最大的一个自然数，最后返回所求值，powers中参数m和n分别表示m为底数n为指数，最后返回所求值。要求使用for循环和函数嵌套(int sum_of_powers中调用powers)实现算法。输出结果如下：
sum of 4 powers of intergers from 1 to 6=2275
注意：部分源程序已存在文件test25_2.cpp中。
请勿修改主函数main和其他函数中的任何内容，仅在函数sum_of_powers和powers的花括号中填写若干语句。
文件test25_2.cpp的内容如下：
include＜iostream.h＞
const int k(4)；
const int n(6)；
int sum_of_powers(int k，int n)，powers(int m，int n)；
void main()
{
cout＜＜"sum of "＜＜k＜＜" powers Of intergers from 1 to "＜＜n＜＜"="；
cout＜＜sum_of_powers(k，n)＜＜endl；
}
int sum_of_powers(int k，int n)
{
}
int powers(int m， int n)
