C graphics programming is a popular topic among computer science students and professionals. One way to learn and practice C graphics programming is to use an online compiler, which allows you to write, run, and debug your code from a web browser.
In this article, we will discuss an online compiler called "OnlineGDB" which is a free, online IDE for C, C++, Python, PHP, Ruby, and Perl. It provides a platform to run and debug your code, along with a built-in code editor and terminal.
To get started with OnlineGDB, you need to create an account and then you can start coding right away. The interface of OnlineGDB is user-friendly and easy to navigate. The editor has all the features you would expect from a modern code editor, such as syntax highlighting, code completion, and line numbering.
One of the most powerful features of OnlineGDB is the ability to debug your code. You can set breakpoints, step through your code, and inspect variables, all from within the browser. This can be especially helpful when working with large and complex codebases.
In this article, we will be discussing a few examples of C graphics programming using OnlineGDB. The first example is a simple program that displays a message on the screen.
#include <graphics.h>
int main()
{
int gd = DETECT, gm;
initgraph(&gd, &gm, "");
outtextxy(100, 100, "Hello, World!");
getch();
closegraph();
return 0;
}
This program uses the graphics.h library to initialize the graphics mode and display a message on the screen. The initgraph() function initializes the graphics mode, and the outtextxy() function displays the message at the specified coordinates on the screen. The getch() function is used to wait for the user to press a key before closing the graphics mode.
The second example is a program that draws a line on the screen.
#include <graphics.h>
int main()
{
int gd = DETECT, gm;
initgraph(&gd, &gm, "");
line(100, 100, 200, 200);
getch();
closegraph();
return 0;
}
This program uses the line() function from the graphics.h library to draw a line on the screen. The line() function takes four arguments: the x and y coordinates of the starting point, and the x and y coordinates of the ending point. In this example, the line is drawn from the point (100, 100) to the point (200, 200).
The third example is a program that draws a circle on the screen.
#include <graphics.h>
int main()
{
int gd = DETECT, gm;
initgraph(&gd, &gm, "");
circle(100, 100, 50);
getch();
closegraph();
return 0;
}
This program uses the circle() function from the graphics.h library to draw a circle on the screen. The circle() function takes three arguments: the x and y coordinates of the center of the circle, and the radius of the circle. In this example, the center of the circle is at the point (100, 100) and the radius is 50.
These are just a few examples of what can be
OnlineGDB is a powerful online compiler that can be used to learn and practice C graphics programming. In addition to the examples provided earlier, there are many other graphics functions that you can use to create more complex and interesting programs. Some examples include:
- The setcolor() function, which sets the current drawing color.
- The setfillstyle() function, which sets the fill pattern for shapes.
- The bar() function, which draws a filled rectangle.
- The arc() function, which draws an arc of a circle.
- The pieslice() function, which draws a pie-shaped slice of a circle.
Another topic related to C graphics programming is the use of mouse and keyboard input. You can use the getch() function to wait for the user to press a key, and the getmouseclick() function to detect mouse clicks. These functions can be used to create interactive programs that respond to user input.
Another topic to consider is the use of libraries for C graphics programming. There are many libraries available that provide additional functionality for graphics programming. Some popular libraries include SDL, OpenGL, and SFML. These libraries can be used to create more complex programs, such as games and animations.
It's also important to note that while OnlineGDB is a great tool for learning and practicing C graphics programming, it may not be suitable for more advanced or professional projects. For those cases, it's recommended to use a more powerful and feature-rich IDE such as Visual Studio, Code::Blocks, or Eclipse, which offer many tools and features to help you write, debug, and optimize your code.
In conclusion, C graphics programming can be a fun and rewarding experience, and online compilers such as OnlineGDB can be a great way to learn and practice. With the right tools and knowledge, you can create a wide variety of programs, from simple graphics to complex games and animations. It's also important to be aware of other libraries, and other related topics that can help you to create more advanced programs.
