First, the introduction of the copy constructorIn general data types, we often use a variable to initialize another variable, for example: int Ten ; int B = A;Using the A variable to initialize the B variable, similarly, the object

1. the concept of templates　　To define the max () function for the maximum value of two numbers, you need to define different overloaded (overload) versions of different data types separately.//function 1.intMaxintXinty);

C + +--pointers1. Pointer baseA pointer is a variable that stores the address of a value, not the value itself. To get the address of a variable, it is implemented by the address operator &.egint 4 ; int *p = &a;Here the pointer p stores the memory

First, we need to understand that all the bit operations in the C language refer to the bitwise operations of the binary numbers. Even if you enter a decimal number, it is stored as a binary form in memory. "=0. Function: The integer number a press

There are a number of iterator implementations in the STL template library that isolate the algorithm implementation and the Access interface, and we can write our own iterators. Iterators in STL are inherited to a common iterator interface:Template

1. Conditional judgmentBy default, every line of code that we write in the program will be executed. But most of the time, we want to execute a piece of code when a certain condition is established.This situation can be done using conditional
