The role of c++this pointer
The functions of this pointer are: 1. Access the member variables and member functions of the current object in the member function. The member function can access the member variables of the object through this pointer. When calling a member function of an object, the compiler automatically The address is passed to the this pointer, so that the this pointer can be used to access the member variables of the object in the member function; 2. Call other member functions in the member function. When a member function calls another member function, the compiler will automatically The address is passed to the this pointer of the called member function.

How to use bubble sort algorithm in C++How to use the bubble sort algorithm in C++ The bubble sort algorithm is a simple but inefficient sorting algorithm that uses multiple comparisons and exchanges to arrange a sequence in order from small to large (or from large to small). Here we will introduce how to implement the bubble sort algorithm using C++ language, and attach detailed code examples. Algorithm principle: The basic idea of the bubble sorting algorithm is to compare adjacent elements one by one from the sequence to be sorted. If the previous element is greater than the latter element, the positions of the two elements are exchanged. After such a comparison, the final
How to use the longest increasing subsequence algorithm in C++How to use the longest increasing subsequence algorithm in C++ requires specific code examples. The longest increasing subsequence (LIS) is a classic algorithm problem, and its solution ideas can be applied to many fields, such as data processing and graph theory. wait. In this article, I will introduce how to use the longest increasing subsequence algorithm in C++ and provide specific code examples. First, let's understand the definition of the longest increasing subsequence. Given a sequence a1,
How to use radix sort algorithm in C++How to use the radix sort algorithm in C++ The radix sort algorithm is a non-comparative sorting algorithm that completes sorting by dividing the elements to be sorted into a limited set of digits. In C++, we can use the radix sort algorithm to sort a set of integers. Below we will discuss in detail how to implement the radix sort algorithm, with specific code examples. Algorithm idea The idea of the radix sorting algorithm is to divide the elements to be sorted into a limited set of digital bits, and then sort the elements on each bit in turn. Sorting on each bit is completed
How to use greedy algorithm in C++How to use the greedy algorithm in C++ The greedy algorithm is an algorithm based on the principle of greedy selection. It makes the currently optimal choice at each step, hoping to eventually obtain the global optimal solution. In C++, we can use greedy algorithms to solve many practical problems. The following will introduce how to use the greedy algorithm in C++ and give specific code examples. 1. The basic principle of the greedy algorithm The greedy algorithm is a heuristic algorithm. Its basic principle is to select the currently optimal solution each time and iterate successively until the global optimal solution is obtained.
