I use it to enhance the performance, features, and support for C, C#, and C++ development in Visual Studio.
It is a powerful, secure text editor designed specifically for programmers.

In this video, I'm explaining C++ structures for beginners. Structures are user-defined data types. They are used to represent information about something more complicated than a single number, character, array of numbers, characters, etc. So, you can use a structure to represent information about a Person, an Animal, a Sport, a Game, a Car...

In this 30-minute programming tutorial, you will learn what are structures in programming, how to create structures, why to use them, how to create variables of the struct type.
All of these topics are covered in the "Introduction to structures" part of this video.
You'll also learn how to use structures and functions and how to pass a structure as a parameter to a function.
In the final part of the video, I'll show you what are nested structures and how to use structure inside another structure

In the end, you can find a task that you can use to test your programming knowledge, together with some useful tips.
In the description, you can also find videos that can help you to solve the programming test.

However, please don't feel obligated to do so. I appreciate every one of you, and I will continue to share valuable content with you regardless of whether you choose to support me in this way. Thank you for being part of the Code Beauty community! ❤️😇

#include <iostream>
using std::cout;
using std::cin;
using std::string;
using std::endl;



struct ** Struct with question + 3 answer and a int for the correct choice **
string questionText;
string answer[3];
int correctAnswer= NULL;
};



bool correctAnswer(int correct) ** ask and check if the answer is correct or not with a bool **
int answer;

cout << "Choose 1-3 : ";
cin >> answer;

while (answer > 3 || answer < 1) { // Check if the user enter a not valid number
cout << "Invalid, Choose 1-3 : ";
cin >> answer;
}

cout << "Correct !" << endl << endl;
return return 1 if valid, 0 if not
}

bool question(Question questionNumber) { // ** List all option
cout << questionNumber.questionText << endl;
for (int j = 0; j < 3; j++) {
cout << questionNumber.answer[j] << endl;
}
return Use the function correctAnswer for asking and checking the answer and return 1 if correct, 0 if not.
}



int main(){
int score = Just for counting the score.

Question create all question with structure here, i don't think we can use a loop for that, cause of all differentes text
question1.questionText = "What is the smallest country ?";
question1.answer[0] = "1. USA";
question1.answer[1] = "2. India";
question1.answer[2] = "3. Vatican City";
question1.correctAnswer = send the correct option to my function



Question question2;
question2.questionText = "What is the biggest animal in the world ?";
question2.answer[0] = "1. Elephant";
question2.answer[1] = "2. Blue whale";
question2.answer[2] = "3. Great white shark";
question2.correctAnswer = 2;



Question question3;
question3.questionText = "How many elements are there in the periodic table of element ?";
question3.answer[0] = "1. 118 elements";
question3.answer[1] = "2. 119 elements";
question3.answer[2] = "3. 120 elements";
question3.correctAnswer = 1;



Question question4;
question4.questionText = "155 % 10 ?";
question4.answer[0] = "1. 15";
question4.answer[1] = "2. 5";
question4.answer[2] = "3. 15, 5";
question4.correctAnswer = 2;



Question question5;
question5.questionText = "Where is Bali";
question5.answer[0] = "1. Malaysia";
question5.answer[1] = "2. Venezuela";
question5.answer[2] = "3. Indonesia";
question5.correctAnswer = 3;



score += if the player choose the correct option the bool function return 1 and add this to my score
score += else, if the player fail, we get 0 and the score don't change
score += question(question3);
score += question(question4);
score += question(question5);



cout << "Your score is : " << score << " /5." << endl;
cin.get();
}

please post c++ algorithms and data structures full course. thanks

You are amazing, but you forgot to answer the most important question of all - what is the difference between a struct and a class... the answer is:

The only difference between a struct and class in C++ is the default accessibility of member variables and methods. In a struct they are public; in a class they are private (at least per my understanding).

My God, you´re like an angel that came to teach us C++! Thank you so much!

[colinmaharaj]

I am actually writing an ORM to abstract my SQL statements. One of the thing I did was create a way to map my C structures into the ORM like a virtual structure. Heavy use of pointers to the structure elements was used and became very helpful in the abstraction.

[patrpatl]

This teacher really wants a lot of comments and likes and shares.
Lets give her it.
Thank you for the free tutorial.

[zaeshanvlogs]

Youre teaching method is excellent, you deserve more views. Dont stop, youll go wayy big some day!

[SA-ojbo]

I was wondering when to use a struct and when to use classes + objects. 2) I think it is always good to show the teacher's solution so we can compare it with ours! Thx for nice tutorials..

[prasannakayitha]

Great explanation! My interest in coding is being developed by watching your videos and by practicing them. Thanks a lot

[sinno]

I didn't understand that part where you said create a structure for answers as well but this is how I did it. I hope it's fine this way as well. It's working completely fine. Please check it out. #include <iostream>
#include <string>

struct Question
{
std::string Questiontext;
std::string options[3];
int Correctanswer;
};

int main()
{
Question question[3];

question[0] = {
"What's your favorite animal?",
{"Dog", "Cat", "Rabbit"},
2};

question[1] = {
"What is your favorite show?",
{"Drake & Josh", "BTR", "iCarly"},
1};

question[2] = {
"What is your favorite color?",
{"blue", "green", "red"},
1};

for (int i = 0; i <= 2; i++)
{
int userInput;
std::cout << question[i].Questiontext << std::endl;
std::cout << "1. " << question[i].options[0] << std::endl;
std::cout << "2. " << question[i].options[1] << std::endl;
std::cout << "3. " << question[i].options[2] << std::endl;
std::cout << std::endl;
std::cout << "Choose 1-3 : ";
std::cin >> userInput;

if (userInput == question[i].Correctanswer)

std::cout << "Correct" << std::endl;
else
{
std::cout << "Incorrect" << std::endl;
}
}
}

I love C++! I'll give it a try to the quiz app this weekend on my free time. Thanks Saldina, you have helped me a lot!

[salihbarknakkaya]

For last 5 day I am just searching out your channel and you even write a comment to me this morning. It is finally feeling me like "I CAN UNDERSTAND!" thanks for everything, you are the best teacher ever!

[steveperrott]

Hello Saldina, I am learning to code in order to create a trading robot in Metatrader 5. I find your teaching moves along nicely. Thank you for doing these C++ lessons.

[m_here]

Programming is fascinating it can make our life more easier I'm lazy and hate doing things on repeat

[chippandenga]

Thank you, I think nobody explains anything better than you do. You are great!!!

[grasshopper]

Namaste Saldina! Your teaching approach is so cool.
Gotta tell you, this is the best c++ channel.
keep up the good work.
