This document discusses C programming and computer graphics. It covers hardware components like display devices (CRT, LCD), input devices (keyboard, mouse, trackball, joystick), and output devices (dot matrix printer, laser printer, plotter). It also discusses algorithms, flowcharts, and different control structures in programming like sequence, selection, and repetition. Flowcharts are used to document the program logic and algorithm. Examples of algorithms and flowcharts for problems like finding the largest of three numbers are included.
