Suggestion is incorrect: it suggests to add bound on generic constantC, but in the scope where it is used there is no such constant, onlyRecord::S.ilog2(). Adding bound withRecord::S.ilog2()doesn't help with this either. Using explicit numeric literal avoids the issue. I looked at a...

template 是 c++ 相当重要的组成部分,堪称 c++语言的一大利器。在大大小小的 c++ 程序中,模板无处不在。c++ templates 作为模板学习的经典书籍,历来被无数 c++学习者所推崇。第二版书籍覆盖了 c++ 11 14 和 17 标准,值得程序猿们精读学习,特此整理学习笔记,将每一部分自认为较为重要的部分逐条陈列,并对少数错误...
5. void SomeFunction() { const int a = 10; ... } 6.private static string astr="abcd"; private const string str = astr+"efg"; 1:不能够换成const。new操作符是须要运行构造函数的,所以无法在编译期间确定 2:能够换成const。我们也看到,Reference类型的常量(除了String)仅仅能是Null。
