we want to find a positive integer k, if it exists, such that the sum of the digits of n taken to the successive powers of p is equal to k * n. In other words: Is there an integer k such as : (a ^ p + b ^ (p+1) + c ^(p+2) + d ^ (p+3) + ...) = n * ...
此时输出结果应为mynameis,然而输出结果为mynameis口(空字符标志打不出来); 所以用字符数组给string赋值时要用assign()

实际上你需要搞明白,private 是访问权限限定,static 表示不要实例化就可以使用,这样就容易理解多了,static 前面加上其它访问权限关键字的效果也以此类推。 static 修饰的成员变量和成员方法习惯上称为静态变量和静态方法,可以直接通过类名来访问,访问语法为: ...
