Introduction to Coding

-

Hi there. Welcome to the world of computer. First of all why coding? Why not 'introduction to programming' or 'introduction to some language'? Let me explain something about this. Beginners to computer programming have to learn coding first then programming or more appropriately coding is fundamental part in making a program. Now you might ask what is difference between coding and programming?? Both looks like same terms right...?

     So here is what we mean by coding, it's the 'Logic' or 'Pattern' that you make in your mind by which you solve some problem. For example if you need to solve some equation like
[ (x + 3) * z ] = 4
                  you will defiantly think of some pattern that you will apply to this to find values of variables. So, this pattern is the code. You practice this all time for doing various stuff in routine life. Like for going out for shopping you make pattern that you will prepare then take some money then go to shopping mall and so on. So in computer coding you will need to 'Practice' for solving same problems in according to computer functionality.
     Similarly programming is referred to some language that will help you to implement this code into making a program that will in turn solve your problem in computer. Let's try this example:
Problem: Make a simple calculator
Solve:
  • First you will think over it that what is a simple calculator? How does it work? What does it do? So it is a device which solves arithmetic operations on numbers like addition, subtraction, multiplication and division.
  • Second you will make a pattern according to which a calculator may work. It will be something like this: 
    • ask for first input
    • ask for operation ( + , - , * , / )
    • ask for second input
    • perform operation
    • tell answer
  • Third you need to specify computer functionality to convert this pattern in computer code. That for now let it be something like this:
    1. function 1: take user input via keyboard in numbers as first value 
      • tell user to enter specified value
      • let user to enter value 
    2. function 2: take user input via keyboard for function that is required to perform
      • tell user to enter specified value
      • let user to enter value
    3. function 3: take user input via keyboard in numbers as second value 
      • tell user to enter specified value
      • let user to enter value
    4. function 4: solve both values according to function specified by user 
    5. function 5: tell user answer
     That's it....!!!! This is "THE" code and it is easy to convert it to program via a language.
 So that's it for coding. Just remember these 3 steps and build your base according to these. I promise you will understand computer coding in best way there is... We will continue this to next topic in which I'll tell you some basic functionality of computer and then we'll jump to coding. Good luck

C++ Console : Basic Graphic Techniques

-
Image
     Console is basically a text panel and this being the reason it is slow for rendering (printing) on it. There are again 2 ways to print on console. Pixel by pixel which is used for printing images and anything is possible with that but this method will yield slow printing speed and that is not very helpful in games or usual applications but in rare cases it may be helpful like making little bit of logos and graphs.      The 2nd method is to use predefined ASCII characters to make a whole shape. This is fast method but since characters are fairly bigger than single pixel (about 1:10 - +) ratio so they are not helpful in making curve shapes. Here is a link   and code to get ASCII table characters view and select which one you might like to use: #include <iostream> using namespace std; void main( ){ cout<<"value\tcharacter"<<endl; for ( int i = 0; i <= 255; i++){ cout<<i<<"\t"<<char(i)<<e

C++ Console : Change Font Size

Font size is not a very big deal but i had to post it's code here because we'll be using it to change the fonts of our console in such ratio that will help us making geometric shapes like squares, easily and perfectly. Here is a list of available ratios that a console supports. You can use either of them: 4:6 6:8 8:8 16:8 5:12 7:12 16:12 12:16 10:18 Code: #include <iostream> #include <Windows.h> using namespace std; HANDLE out = GetStdHandle(STD_OUTPUT_HANDLE); void fontsize(int,int); void main(){ fontsize(8, 8); cout << "This is a symmetrical font" << endl; system("pause"); } void fontsize(int a, int b){ PCONSOLE_FONT_INFOEX lpConsoleCurrentFontEx = new CONSOLE_FONT_INFOEX(); lpConsoleCurrentFontEx->cbSize = sizeof(CONSOLE_FONT_INFOEX); GetCurrentConsoleFontEx(out, 0, lpConsoleCurrentFontEx); lpConsoleCurrentFontEx->dwFontSize.X = a; lpConsoleCurrentFontEx->

C++ Console : Color

     It's obvious that in modern Graphical and Colored world of computer, it's kind of disappointment to work in weird looking console with black and white interface. But don't be disappointed about that. It's just the beginning. Software world has endless possibilities. Would you believe that you can even make whole game in console?? Yup, when i was introduced to programming via C++ console apps, i had no idea that it could be this much fun. I even wrote generic codes for some graphical stuff. It's really helpful in learning coding.      Let's see what is there to get colorized... There are 2 ways to get colored. One is to just make it all colored. Like green text with black background: Simple color:       But the problem with this type of coloring is that it is not very creative. You'll have only one color at a time. And that is the problem. We can't achieve multicolored interface. But on the other hand this is simple way to achieve colored in
