2. Error prone points 1 When we use the scanf statement, many friends who have just started are prone to make the following mistakes when we first contact this statement. When using scanf ("% d", & n), we must add an & (address character). Incorrect usage: #include <bits/stdc++.h> using namespace std; int main() { ...

Where you write, you will slowly add before and after. The format is a little chaotic. Don't be angry with the reader As for what depth to learn and what to do in the en ...

This article describes how to build a simple tree to experience the use of the following running script tree. An understanding of tick Suppose you want to do two things in order, find the goal and grasp the goal (you can't grasp it until you find it first). The plan is as follows, PS: the top two layers can be regarded as strategy (gene ...

catalogue 1, Why is there dynamic memory allocation 2, Dynamic memory function   malloc and free calloc realloc 1, Why is there dynamic memory allocation   There are two ways to open up space we have learned before: int main() { int a = 5; char ch = 'b'; int arr[20] = { 0 }; } The above ways of developing memory are tha ...

In the computer three-dimensional world, if you want to simulate a real object and make its surface look more realistic, you need to use the "texture mapping" technology. In short, it is a way to map 2D images onto 3D objects. Generally speaking, texture is one or more 2D images representing the surface details of an object, also know ...

Using lighting in 3D scene is very simple. We don't need to assign color values to each vertex of the model object. As long as we use some kind of lighting and set the material of the model object, Direct3D will calculate the color value of each vertex according to the lighting model algorithm to make the model produce color. As we have roughly ...

Monotone stack handles the problem of size comparison in the overall O(n) time by maintaining the monotonic increment (decrement) of the value in the stack. 739 daily temperature Given the daily temperature, it is required to wait a few days for each day to wait for a warmer day. If there is no warmer weather after that day, it is recorded as ...

Introduction of Lambda expression Some function object classes are only used to define an object, and this object is used only once, which is a bit wasteful. Moreover, defining a function object class and using it can be far apart, and it can be cumbersome to see exactly what its operator() member function does. For function object classes th ...
