Two expressions of string

1.c++ Inherited c Writing , character string c The style of writing ：

    char b[4] = { 'w','c','c','\0'};
    char a[6] = { "loveu" };
    /*char a[6] = { "loveuy" }; By default, it will be followed by /0 To indicate the end , So it's better than 6 One less bit to store /0, This writing will report an error   */

2.C++ Their own string type

string s = "run";

example ：

#include<iostream>
using namespace std;
int main() {
	// character string  c The style of writing 
	char b[4] = { 'w','c','c','\0'};
	char a[6] = { "loveu" };
	/*char a[6] = { "loveuy" }; By default, it will be followed by /0 To indicate the end , So it's better than 6 One less bit to store /0, This writing will report an error    */
	cout << a <<endl;
	cout << b << endl;
	// character string  c++ Style writing 
	string s = "run";
	cout << s << endl;
	// String common functions 
	// Connect 
	string s1 = "run";
	string s2 = "go";
	string str = s1 + s2;
	cout << str << endl;
	// Copy 
	string s3;
	s3 = s2;
	cout << s3;
	// Return string  s1  The length of .
	return 0;

}

Add ： Connection copy function of string （strcpy,strcat） Can't use , Personal access to data is considered abandoned by the version , The available methods are given in the code .
