which is a template parameter, fixed on compile time). It is as efficient in terms of storage size as an ordinary array declared with the language's bracket syntax ([]). This class merely adds a layer of member and global functions to it, so that arrays can be used ...
and the parameter "allocatedSize"// is the size of the mallocated block. The string must be// \0-terminated, so allocatedSize >= size + 1 and data[size] == '\0'./// So if you want a 2-character string, pass malloc(3) as "data",// pass 2 as "size", and pass...

因此,std::array在性能方面的最大优势是,它消除了std::vector为其灵活性所付出的间接代价。例如:...
void g( int(&f1)(int), int(*f2)(double) ) {} // 作为模板参数传入函数地址 // Pass in the function address as a template parameter template< int(*F)(int) > struct Templ {}; struct Foo { int mf(int) { return 3; } int mf(double) { return 4; } }; struct Emp { void ...
如果你使用字符串作为键,上述建议仍然适用,但您可能还想尝试 tsl::array_map。 它提供了大字符串的最佳查找速度之一,同时具有最低的内存使用率。 主要缺点是重新哈希过程很慢,并且需要一些备用内存将字符串从旧映射复制到新映射(它不能像使用 std::string 作为键的其他哈希映射那样使用 std::move )。 但如果你...
