1.The general global variables are placed inside the CPP file instead of . h inside. Otherwise easy to mess up, this chaos several times good, first remember such a coding specification. Think that we are introduced to more trouble, but the

The problem of deep copy and shallow copy in C + + is a point of knowledge that deserves our attention, and if you don't pay attention in programming, you may be negligent and cause a bug. This article tells you a lot about C + + shades.We know that

I. Description of requirementsEnter a string, write the program to find the longest consecutive character in the string, and determine the number of consecutive occurrences.For example, the longest consecutive character in "123444445" is 4, and its

1. What is the role of #include ?This compilation instruction causes the preprocessor to add the contents of the iostream file to the program, which is a typical preprocessing operation that replaces or adds text before the source code is

C + + implementation of single-linked list#include using namespace std;typedef int datatype;struct node// struct in C + + and class public and private properties are different {Node (const datatype &d): _data (d), _next (NULL) {cout _data);

Using pointer variables, the function implements the output of 3 integers in order from large to small. Solution: Program:#include void swap (int *ptr1, int *ptr2){int temp = *PTR1;*PTR1 = *PTR2;*PTR2 = temp;}void Exchange (int *q1, int *q2,int *q3)

Constants and variables look exactly the same, but the constant value is not allowed to be modified . We use the const keyword to declare a constant.Example: const int a=10;int const A=10;Both ways can declare a constant effect to be the same.We can
