What is pset4 in the CS50 (2015) course of edX? How can I solve it?
Okay, that makes sense. Are there any specific programming languages or tools that I need to use for pset4?
Yes, for pset4, you need to use the C programming language and the library called 'bmp.h.' You can download the library from the CS50 course site. Additionally, you can use a program called GIMP, which is a free and open-source image editing software, to help you visualize and manipulate the images in the pset4 problems.
