   changing font size and color

   I would similar to know how I modify the color of font and the size. The simple code below would be squeamish to run into displayed on a white background and the text red and bigger. Is this possible in the command prompt window and if so how
   

   Code:

                           
                             
                               
                                 
                                   
   1 2 3 four 5 6 7 8 9 10 11 12
                                   
                                     #include<stdio.h>int main(){printf("\n");    printf("------------\north");    printf("How-do-you-do WORLD\n");    printf("------------\northward");    printf("\northward");return (0);}

   the easiest way i found to change WINDOWS CONSOLE font and background colors is past including WINDOWS.H, then using the command ONCE similar whne you declare a variable

   Code:

                         HANDLE hConsole;  hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

   then everytime you want a color change use

   Code:

   SetConsoleTextAttribute(hConsole, NUMBER);

   NUMBER is a number 0-255, in that location arranged in "blocks"

   groups of xvi

   first xvi, black background, and then 16 colors of text
   second xvi, next color background, so 16 colors of text
   etc

   fix a number, then print text and then see what colors it is, then modify number and run once again till you get the desired colors!

   this does NOT modify the entire background to a colour, if yous print "HELLO" the background volition be the color for ONLY the 5 spaces that the letters are, and so the text would exist the reg color.

   hope this helps, and take fun!

   command prompt IS the windows console............

   equally command.exe (or CMD.exe depending on which windows you lot use) is what handles your "msdos" programs for console mode, wither you call the prompt get-go, or your program calls it to run.

   Usually, you write the lawmaking in an editor that comes with your compiler - that'due south what they mean past "IDE" - Integrated Development Environment. Then, when you run your lawmaking, your panel programme will automatically open up a console window - a DOS type window, aka "Command Prompt window", and that window volition have it'south ain colour for background and text, and font settings.

   The IDE will also accept other tools for helping yous code improve and faster - typically all primal words in C are highlighted for you in a dissimilar colour, information technology will accept a debugger you tin use to stride through your lawmaking and sentinel variable values, set up breakpoints yous tin can run to, etc. It may fifty-fifty have a profiler.

   You lot change the console window, past opening it, and then correct clicking on the top bar of the window, and choosing either "Properties" or "Default". They both take the aforementioned settings for both colour and font, merely any change you lot make will exist temporary, (one fourth dimension only), if you choose "Properties". For permanent changes, choose "Default", and make your changes at that place, and salve them.

   I'm old fashioned, so I like the blue background and white letters, and 8x12 font size.

    Here is a simple example of setting the console's font size:
    

    Lawmaking:

    #include <stdio.h> #include <stdlib.h> #include <Windows.h>  int GetFontSize(HANDLE windowHandle, COORD *size)     {     CONSOLE_FONT_INFOEX font = { sizeof(CONSOLE_FONT_INFOEX) };      if (!GetCurrentConsoleFontEx(windowHandle, 0, &font))         {         render 0;         }      *size = font.dwFontSize;      return 1;     }  int SetFontSize(HANDLE windowHandle, COORD size)     {     CONSOLE_FONT_INFOEX font = { sizeof(CONSOLE_FONT_INFOEX) };      if (!GetCurrentConsoleFontEx(windowHandle, 0, &font))         {         return 0;         }      font.dwFontSize = size;      if (!SetCurrentConsoleFontEx(windowHandle, 0, &font))         {         render 0;         }      render 1;     }  int main(void)     {     HANDLE h = GetStdHandle(STD_OUTPUT_HANDLE);     COORD size;      if (GetFontSize(h, &size))         {         /* Grow by l% */         size.10 += (SHORT)(size.X * .5);         size.Y += (SHORT)(size.Y * .5);         SetFontSize(h, size);         }      puts("Blah apathetic text");      return EXIT_SUCCESS;     }

    Just note that the console is not rich text. Setting the font size with change everything.

    Colours are quite easy. Just use the conio.h fucntions.

    Changing fonts is much more difficult. Basically the console isn't designed to handle mixed fonts. Yous tin write your own console (medium hard), on pinnacle of the Windows GDI functions, or yous can hack into the console (very hard), or you tin can just brandish text in a normal windows (relatively piece of cake).

    But notation that the console is not rich text. Setting the font size with change everything.

    many thanks for this example. I cut and pasted the vim text editor and saved information technology equally a C file. when I tried to compile it in the control prompt I got several errors in part get font size CONSOLE_FONT_INFOEX un alleged not really sure where to go from here

    Are you linking with Kernel32.lib or Kernel32.dll? The example uses the Windows API to claw into the panel, and if you lot're building manually from the control line you'll need to link with the appropriate libraries.

    Thank you for your reply! I don't recollect I am using a windows API. This has always been a question and a business of mine! I would like some advice and guidance here. I am using the text editor Vim 7.3 then manually compiling the lawmaking in the windows CMD PROMPT. I save the lawmaking in Vim with the extension c. (Example save equally lawmaking.c) I and so go to the CMD PROMPT go to the correct directory and type gcc code.c -o code once the lawmaking is compiled I type code in the prompt line and the program runs. So getting dorsum to your advice or question I have no idea if I am linking with kernel32.lib or kernel32.dll I think I am building from the command line only will stand up corrected. I will also stand guided on recommendation of other software to write and compile code.. Many thanks Rodney
