使用字符串联接在字符串中获取反斜杠

backslash = "\\"
print(backslash)  # 输出：\

String backslash = "\\";
System.out.println(backslash);  // 输出：\

var backslash = "\\";
console.log(backslash);  // 输出：\

#include <iostream>
using namespace std;

int main() {
    string backslash = "\\";
    cout << backslash << endl;  // 输出：\
    return 0;
}

str1 = "Hello"
str2 = "World"
result = str1 + " " + str2
print(result)  # 输出：Hello World

String str1 = "Hello";
String str2 = "World";
String result = str1 + " " + str2;
System.out.println(result);  // 输出：Hello World

var str1 = "Hello";
var str2 = "World";
var result = str1 + " " + str2;
console.log(result);  // 输出：Hello World

#include <iostream>
using namespace std;

int main() {
    string str1 = "Hello";
    string str2 = "World";
    string result = str1 + " " + str2;
    cout << result << endl;  // 输出：Hello World
    return 0;
}
