How to Get Color in C Program

Changing Drawing Color

1. 
   Include the graphics library. The C graphics library allows you to draw objects, as well as adjust their color. You can get access to the graphics library by including it at the top of your program:

   #include 

2. 
   Include the Console Input and Output library. You can use this library to easily capture a user's input. Add the library below the graphics.h library:

   #include #include 

3. 
   Initialize the variables for the graphics driver and mode. You'll need to do this before you begin drawing objects, so that the program has access to the system graphics drivers. This will create an area on the screen that the object will be drawn on.

   #include #include main() { int gd = DETECT, gm; initgraph(&gd, &gm, "C:TCBGI"); // Change this to the path of your compiler } 

4. 
   Set the color of the object you want to draw. Before coding in an object, use the setcolor function to define the color of the object you are about to draw: ^{[3] X Research source}

   #include #include main() { int gd = DETECT, gm; initgraph(&gd, &gm, "C:TCBGI"); setcolor(BLUE); // You can enter "1" instead of "BLUE" to get the same color, but this is not as readable } 

5. 
   Draw an object of your choice. For this example, you'll be drawing a rectangle using the rectangle function. You can use any of the graphics.h drawing tools to draw in the color that you set.

   #include #include main() { int gd = DETECT, gm; initgraph(&gd, &gm, "C:TCBGI"); setcolor(BLUE); rectangle(50,50,100,100); // These numbers indicate the location of the left-top and right-bottom corners } 

6. 
   Finish off the program and test it. Add the getch command and turn off the graphics area as you close the program. Compile it and give it a test run.

   #include #include main() { int gd = DETECT, gm; initgraph(&gd, &gm, "C:TCBGI"); setcolor(BLUE); rectangle(50,50,100,100); getch(); closegraph(); return 0; }
