Did not learn the principle of code compilation, and did not have the interest to learn the relevant principles of the compiler, but recently by reading Google Open source project Gtest, I slightly touched. Code: Main Test example TEST Macro

Erase ():The erase function is prototyped as follows:(1) string& erase (size_t pos = 0, size_t n = npos);(2) iterator erase (iterator position);(3) Iterator erase (iterator first, iterator last);That means there are three ways to use:(1) Erase

The containers in the STL are stored in two categories, one for containers that are stored as arrays (e.g. vectors, deque), and those that are stored in discontinuous nodes (for example, list, set, map). There are some issues to be aware of when

Checks if an object was compatible with a given type.An was expression evaluates totrue if the provided expression was non-null, and the provided object can be Cast to the provided type without causing a exception to be thrown.The is keyword

Origin:. The origin of net technology can be said to be a most basic point of view, code reuse.How to reuse:The former reuse method is the class library, the use of a good class library is very enjoyable, but the reality is often frustrating,

The three basic features of object-oriented are encapsulation, inheritance, and polymorphism. Encapsulation simply combines a set of data structures and related operations defined on them into a class, inheriting a parent-child relationship, child

It can be solved by brute-force recursion. It should not be TLE, but we should consider memory optimization. If f (I, j) is set, it indicates the number of solutions when I is set to J. F (I, j) = f (1, J-1) + F (2, J-1) + ...... + F (I-1, J-1) (4>
