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. Printf('Square root of %.2f = %.Setcolor(color), setbkcolor(color), setlinestyle(style, pattern,thickness). Computes the square root of num and stores in root. The function is defined in the math.h header file.

To compute the square root of a number, you can use the sqrt() library function. Suppose, you want to find the square root of a number. And, these library functions help you in that they do the same thing on every computer.Įxample: Square root using sqrt() function

With ever-changing real-world needs, your application is expected to work every time, everywhere. You shouldn't worry about creating them once again.

Since the general functions like printing to a screen, calculating the square root, and many more are already written.

In the process, they are able to create the most efficient code optimized for maximum performance.ģ. Since, the functions are 'standard library' functions, a dedicated group of developers constantly make them better. The functions are optimized for performance
