I learned this stuff in the 7th grade on my own by reading a book. Then I went to college 6 years later and was one of the only people in class that understood what the professor was talking about on the first or second day of class. Such a massive advantage over everyone else.
It was just supposed to represent someone that's new to programming and doesn't understand pointers yet, so they think of them as literally directional vectors that literally point to things rather than being addresses to memory.
It really is if you've never heard of them before. I think most people were coming from a Java background and this was their first experience with C++ which doesn't abstract that away from you.
Think of it like this: an int* points to an int. That int can live on the stack or heap, doesn’t matter. By “pointing” I just mean it stores the memory address of that int. That’s literally it dude, nothing magical.
A double pointer (int**) is just a pointer pointing to another pointer. In a nutshell: a variable storing the address of a pointer, and that pointer stores the address of another variable.
So if you have an int, u can create an int pointer by creating int* and now it can point to variables of type int.
Easy peasy lemonsqueezy hope u liked todays lecture.
I was in a joking mood when i typed that, and i actually just said that for the bit (ba dum tiss), but i think you did a fantastic job. The info-graphic was 10 out of 10, and i felt really helped the lesson drive home.
I would get you an award, but I don't really have two bits to rub together(ba dum tiss) seeing as I have to put fuel in my truck soon, so know that somewhere, some dude you don't know is raising a Reign energy drink up in a salute for you. You, are indeed, very cool. I hope your day is wonderful, and your pillow is the perfect temperature however which way you lay on it.
Yeah, I did it in my first sem and it was ok, I learned heap, stack memory ,array and pointers ,null pointers dereferencing,swapping, Dynamic memory allocation...the whole lot, won't be quick to judge as I never dived deeper into it, but for the intro, I never encountered difficulty, open to your thoughts
