Who is the best programmer of our time?

Image
  Gennady Korotkevich This guy has won Google’s programming contests for 6 years in a row now. At just 11 years old he was able to obtain a silver medal at International Olympiad in Informatics: a feat that even the best senior software developers and some Computer Science professors would not be able to accomplish. He then proceeded to to get gold medals in the following years, with three consecutive years achieving absolute first place. For more information of his feats check his Wiki page. This guy is to programming , what Magnus Carlsen is to chess or Terence Tao is to Math. He outclassed even the best programmers at 11 years old, and for the past few years, no one was able to get close to his programming skill. Most of the time I would expect a person to be the best in his field for a year then the honor would go to another person the following year. This is the case for almost every other sciences (Math, Physics, etc…) not for this guy, who has consistently been ranked the nu...

Which is better: Python or C++?

Image
    Python or C++ Many people want to get started with coding but they don’t know which language should they start with. Both the languages are very popular among the tech community and you can start with any programming language. But I will still try to differentiate between two in terms of different features they have. C++ C++ is more  complicated , low level language. The syntax has more rules and conventions to follow. It’s  closer  to hardware. C++ is a better option to develop  games  and other systems. The code needs to be  compiled  first before running the program C++ takes  more  number of lines of code to write the logic. It doesn't have  garbage collection  functionality which python has C++ programs are little bit  faster  to run compared to Python Python Python is  easier  to learn with its simple syntax. Python is  dynamically  typed language. It is  interpreted  lang...
  C , C++ , Python Or Java   As a learner/ experimenter , I would recommend first by just search the internet for different languages that are available , just to get a brief about what you are getting into. From my personal point of view,I would recommend starting with C. Do study different ways to manipulate code for computer to reveal its secrets.C is a very beautiful language and it finds its backbone in many different industries(LINUX ,for example) From that step ,you can move to C++.I would recommend finding why do we need C++?,what problems/limitation of C? This is generally a good practice and will surely help if you want to realize the fundamentals of Computer Science. I think from that point you can easily switch between different languages or can move to Python/Java.You will find many things you already know and will definitely find things you have no idea about.You can compare different aspects of your code in different languages(if needed) One last thing you need...

Should I use pointers all the time in C++?

Image
Contrary to most answers here, I have no particular aversion to pointer implementations in C++. To me, a pointer is just a variable. So saying ‘pointers are bad’ is saying variables are bad. After all it is really just an unsigned integer that contains an address and has a type associated with it. An indirect reference serves a purpose. It allows access without copying and replacing values and allows objects to cross context boundaries. Of course the possibility of abuse and error is present in such situations, but it always is anyway really. Any variable can contain a bad value, be it a pointer or a direct variable. C++ has some tricks up its sleeve with references, lvalue references, smart casting, etc, that do indeed make for safer code constructs when indirection and pass-by-reference is used — which is all the time. Of course it is encouraged to use these tools to write more robust and reusable code. But it is not altogether possible to avoid pointer implementations in a lot of s...

What is the difference between an array of a pointer and a pointer to an array with an example?

In C    Array  is a collection of similar data items, whereas Pointer  is a special kind of Variable that can hold the address of another variable. So, array of pointer means an array whose contents/data items are pointers. Suppose, int *a=&x; int *b=&y;  int *c=&&z; [ Here a,b,c are 3 int type pointer who are holding address of 3 integers x,y and z] Now, int M[10]; (M is an int array i.e can hold int data elements and is of size 10). so, M[10]={a,b,c}; ——-> This is Array of pointers, i.e the array is holing a number of pointers . Where as suppose we have created a new pointer of int type and we are initializing it with the previously created array’s address i.e address of a, like int *S=a; So, this is pointer to an array, i.e the pointer is pointing to an array.

How do I write a script for the MATLAB code?

  Scripts are the simplest kind of program file because they have no input or output arguments. They are useful for automating series of   MATLAB commands, such as computations that you have to perform repeatedly from the command line or series of commands you have to reference. You can create a new script in the following ways: Highlight commands from the Command History, right-click, and select  Create Script . Click the  New Script  button on the  Home  tab. Use the  edit  function. For example,  edit new_file_name  creates (if the file does not exist) and opens the file  new_file_name . If  new_file_name  is unspecified, MATLAB opens a new file called  Untitled . After you create a script, you can add code to the script and save it. For example, you can save this code that generates random numbers from 0 through 100 as a script called numGenerator.m . columns = 10000; rows = 1; bins = columns/100; rng(no...
