Many GUI programming is stopped in C++ because they don’t have the default graphics library.

The next step is to go to the project and select project options followed by the parameter tab and paste the following in a linker tab: lbgi -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32. To work with DevC++, we need to download graphics.h and libbgi.

Since we need a good framework to develop a good feature to draw, here in this article, I have used DevC++ IDE for that we need a certain package in addition to work with Graphics, to download this, we can refer WinBGIm to install the graphics library. So, a window or canvas is the main feature to show the output. The graphics are a two-dimensional concept to implement this, we need implementation and few functions in C++ programming. Setcolor(color), setbkcolor(color), setlinestyle(style, pattern,thickness). Web development, programming languages, Software testing & others stdio.h : This library is use to use the printf() function, the header file should be included in the program.Start Your Free Software Development Course Implementation: Let’s discuss the implementation of the basic libraries with a C program:ġ. The difference between a character arrayĪnd a string is that a string is terminated with a special character ‘\0’. Strings are defined as an array of characters. The stdio.h header defines three variable types, several macros, and variousįunction for performing input and output.ĭefines date and time handling functions. In this library take double as an argument and return double as the result. The math.h header defines various mathematical functions and one macro. These limits specify that a variable cannot store any value beyond these limits, for example-Īn unsigned character can store up to a maximum value of 255. If the expression is a nonzero value, the assert macro does nothing.Ī set of functions for manipulating complex numbers.ĭefines macro constants specifying the implementation-specific properties of the It checks the value of an expression that we expect to be true under normal circumstances.
