When you hit the code, it happened that the priority of the left-shift operator was lower than the addition operator and left-shifted. Then I found this watch ... Priority level Operator Name or meaning Use form

for the public inheritance method:(1) The public member of the parent class becomes the public member of the subclass, allowing code outside the class to access those members ;(2) The private member of the parent class is still the private member of

What is a containerFirst, we have to understand what a container is, in C + +, where a container is defined as having an object type on the Datastore, which can hold other objects or pointers to other pairs of objects, which are called containers.

STL, the standard Template Library, is a highly efficient C + + library with industrial strength.It is housed in the C + + standard library, which is the newest and most revolutionary part of the Ansi/iso C + + standard. The library contains many

1, identifiers are divided into three categories: keywords, predefined identifiers, user identifiers. Keywords have a special effect in C, so you can't use them like int, print, and so on. A predefined identifier is a pre-defined identifier that has

Template metaprogramming (TMP, templating Meta programming) is the process of writing template-based C + + programs and compilations. Template metaprogramming is written in C + +, and the compiler compiles the materialized process. In other words,

Original question:Write a program to print ahistogram of the lengths of words on its input. It's easy-to-draw thehistogram with the bars horizontal; A vertical orientation is more challenging.This is my first hundred lines of code (with comments,

The process for calling Python in C + + is as follows:1:includt; note Do not import file 2: Initialize Python interpreter: Py_initialize () 3: Invoke other PYTHON/C APIs to do some environment Initialization of the operation. For example, a Python

0 Base starts with C language. In the book see the single-chip assembly language and embedded C language comparison, more useful. 1. The main function in the embedded C program is the main program in the assembler, and the function in the embedded C
