In my case the password was not there anymore. Is it possible that my system or compiler is re-writing this memory space?

Recursion: the most overrated wet dream of computer science academics. In practice, it's almost always better in terms of performance, resources, readability and maintainability to use iterative methods.

Note: realloc() could fail, this video explains how to handle it: ruclips.net/video/skqCnhhA0ZY/видео.html. 🙂

I also noticed that if you malloc space into pointer a and realloc it into pointer b you cannot free(a). You still have access to the address in a but it seems that realloc frees the variable. Then looking into that value in a it might be the original one or not. On the safety concerns calloc does not seem to solve the issue, we would need a "crealloc" or something that when copies the data from one place to another zeros the original memory value too if I got it right.

End program. End program. End program. End program. End program. End program. End program. End program.End program. End program. End program. End program. End program. End program. End program.

sure, but if it returns NULL would it not be better to store the return address to a different pointer and then determine if string will point to it? this happens more often than one would think in small embedded chips.

first thank for the videos I am learning a lot through them! I did tried the clock part for this example and not sure why but I am getting in many runs a faster time for the calloc allocation. Any idea what might be going on? I am using gcc in an ubuntu os.

If I have old laptop which support win 8.1 or can say ideal windows environment on that laptop. My Q's is Vscode not supported any more now on win 8.1 can we use pycharm for chatbot etc kind of programming in win 8.1

love from Bangladesh!

46 years as a software developer (over half doing C/C++) and this is the most succinct and complete example of the UNIX/LINUX time code without the pages and pages of boilerplate. You are a true craftsman!

In the second method (iterating through characters until we reach the null terminator), you may have forgotten to remove the #include for the string.h since we no longer are using strlen function.

Dude, You have helped me a ton more than possible, you explain things so much better than most tutorials out there, Thank you so much!

for some reason i really do not like and having a hard time comprehending the for loop that contains i j k as indices at the same time. So instead I prefer while loop.

Do you have any videos on unit testing in c?

Sir non overlapping in substring example

I have watched many videos teaching what pointer is and how to use, but only this one can make me truly understand how to use pointer in a few minutes. This must be a good day for me, as I have learnt thing from a genius.

Is is good to use delete operator inside the destructor?

❤nice😊

you can even remove all the elses because you are returning from all the ifs

// While practicing functions, I encountered an error. Can you explain why? // I tried using `void` as an argument in the function call. // Why can't `void` be used this way, and what is the proper way to call a function that takes no arguments? void myFunction(void) { // Function body } int main() { myFunction(void); // Why is this incorrect? return 0; }

Nice explanation

Nice videos mate! Appreciate it❤

wouldnt the break case have to be if (n == 0) return 1 Because 0! = 1

you are the besttttt!!!!!!!!!! thank youu

Thank youuu

This IDE software so beautiful, Can I know this software which you use to program

Back on the day when I worked on Big Blue Heavy Iron (IBM mainframes), we called it "hat racking" because we'd drag the coat and hat rack into our office and explain our code to it. Prefer some entity a little more grown up than using something I would have bathed with when I was six years old. But you do produce impressive and helpful videos! Very grateful as they have helped me unwind some exceedingly bad habits from my career days.

simple and useful, thank you guys for the help

what if user input numbers?Is it same?

Hi there..We can use strrev() right

Great course. But, also include how to setup the code environment like code editor and compiler for C because there's still some beginners don't know how do it like me.

Great!!!

C is fun! And useful. Thank you!

I really appreciate what you doing. I'm learning c now and all of those video, even short one like these when you explain these thing clear are very useful! Thank you. I would also like if you would do videos when you build some big projects in c and show the process, and maybe some networking in c, socket extra... Thanks again❤🎉

I have to say that I am eternally grateful for all the work you do. This is one of the best coding tutorials I've watched. And I believe that like many here I've watched A LOT!!! So that is really saying something. Your voice is excellent for narration and the way you set up your windows and explain everything so concisely and in more than one way is just so damn good. I am sorry I cannot pay you monetarily but sir I truly appreciate your work. I hope you realize just how much of a contribution you have done for the coding community. Also it's very surprising that for such an important and ubiquitous language like C, there is so much lacking in terms of good videos like for other languages. Once again, thank you very much and the best of luck in everything you do!

Today, I secured an internship in the imaging and video field, where I'll primarily be coding in C! Your videos have sparked my interest in learning C and have paved the way for opportunities such as teaching assistant in a procedural programming course and now this internship. Thank you!

Portfolio Courses, wanna collab it was really good

Please, is there a way of doing it with Smart Pointers?

I did some modification to your program. I even tried using Smart Pointers but it didn't work. #include <iostream> #include <vector> #include <string> #include <math.h> class Shape { public: virtual double area() = 0; virtual const std::string name() const = 0; }; class Square : public Shape { public: Square(double side) : m_side(side) {} virtual double area() final { return pow(m_side, 2); } virtual const std::string name() const { return "square"; } ~Square() {} private: double m_side; }; class Triangle : public Shape { public: Triangle(double base, double height) : m_base(base), m_height(height) {} virtual double area() final { return 0.5 * m_base * m_height; } virtual const std::string name() const { return "triangle"; } ~Triangle() {} private: double m_base; double m_height; }; class Parallelogram : public Shape { public: Parallelogram(double side1, double side2) : m_side1(side1), m_side2(side2) {} virtual double area() final { return m_side1 * m_side2; } virtual const std::string name() const { return "parallelogram"; } ~Parallelogram() {} private: double m_side1; double m_side2; }; class Circle : public Shape { public: static double pi; Circle(double radius) : m_radius(radius) {} virtual double area() final { return pi * pow(m_radius, 2); } virtual const std::string name() const { return "circle"; } ~Circle() {} private: double m_radius; }; double Circle::pi = 3.1452; int main() { Shape* shapes[4] = { new Square(4), new Triangle(6, 9), new Parallelogram(11, 6), new Circle(7) }; for (int i{ 0 }; i < 4; ++i) { std::cout << "Area of " << shapes[i]->name() << ": " << shapes[i]->area() << " sq units "; } for (int i{ 0 }; i < 4; ++i) { delete[] shapes[i]; } return 0; }

i love this informative video. pls make more. Thank u love you so much!! This have me new ideas. Please remember my name as i might come to see you soon. ttyl!!! xoxo

This was very helpful, thank you so much! Also I know it's 2 year's old but this video is rock solid and the instruction's and explaination's are great!

bro thx so much love how it turned out :)

Sir, i start programming in C as hobby. But now i am enjoying. It will more enjoyable if you teach about Graphics in c. Thanks for your amazing teaching.

can you show plz

in which compiler are you execute

Great explanation! In the embedded world I would argue that the "int * p3" decelerationis the most common. Although, in function declerations it would typically be "int const * p3"

Can you make a video on the Dijkstra's algorithm in Python or C?

I didn't understand how you calculated mid, wouldn't you have to sum the two extremes and divided them by 2 to find the mid point?
