This will be my first post in this subsection this month, and it will be about the implementation of Strings and Classes.

Strings:

Strings are a type of variable that can be very useful while programming any kind of application that requires user input, because it is better to use than a char variable and it will help if you are reading info from a text file. Here is some code for a basic implementation of a string variable and its use in an application:

Code:

#include <iostream>
#include <string>

using namespace std;

int main()
{
    //makes the string, which is named "username"
    string username;
    //prints a question to the console
    cout << "Hello, what is your name? ";
    //receives input to change the string username's value
    cin >> username;
    //prints text, then the string's value, then more text, then ends the line
    cout << "Hello, " << username << "! Have a nice stay in hell." << endl;
    // returns 0 if program ran successfully
    return 0;
}


This is a pretty simple program, but the uses for strings are almost endless in coding applications. Next up are classes and how to initialize them.

Classes:

Classes in C++ are very useful, especially if you want to eventually make a game or a program that keeps track of employees, people you need to kill, local fruit fuckers, etc.

Code:

#include <iostream>
#include <string>

using namespace std;

//makes the class "Person"
class Person {
//everything under public is accesible by the program
public:
      //the start of the variables
      Person(string name, int age) {
            this->name = name;
            this->age = age;
      }
      string getName() {
            return name;
      }
      int getAge() {
            return age;
      }
//everything under private is accessible only through the get<name>() commands, if initialized in the public section
private:
      string name;
      int age;
};

int main() {
      cout << "Creating a person..." << endl;
      //makes an instance of the class "Person"
      Person johnDoe("John Doe", 25);
      cout << "Person's name: " << johnDoe.getName() << endl;
      cout << "Person's age: " << johnDoe.getAge() << endl;
      http://johnDoe.getName and getAge are able to access the private variables
      return 0;
}

that wraps up this post, I hope you got something out of it, have a good day

Useful.

I LOVE YOU. <3 Finally I got what classes are...

glad to help
