Let's talk about the idea of merging sort: The merging Sort method combines two (or more) ordered tables into a new ordered table, which divides the ordered sequences into ordered sequences, and then merges the sequential subsequence into the whole

This is the language feature that C + + will have. If you use a library, he has a 衋 BC, but you accidentally define a variable called ABC, which causes a redefinition error. So in order to avoid this phenomenon, C + + introduced the concept of

C + + as a widely used language, from its inception, is now more than 30 years of history. In the past 30 years, C + + itself in the constant update, change, in 2011, but also launched its latest standard c++11 (reportedly c++14 also want to launch).

A simple example program that explains how pthread_cond_wait and Pthread_cond_broadcast are used. function definition: int pthread_cond_wait (pthread_cond_t *cond, pthread_mutex_t *mutex) int Pthread_cond_broadcast (pthread_cond_t *cond) Function

The generalized table forms a two-fork tree input, shaped like: A (B (C (,), F), G (H,i)). That is, the pre-sequence traversal format The program assumes that no spaces are entered and that each node uses a single letter to represent the use of

Templates are the basis for generic programming. The so-called generic programming is to write a type-independent logic code, is a reusable way. Templates are divided into template functions and template classes. First, we do not use the template

The assert meaning is an assertion, which is a macro defined in the Cassert header file of standard C + + to determine whether the value of a conditional expression is ture, if not true, the program terminates, and an error is reported, which makes
