45 Degree Angle Generation Program in C: #Include #Include

This C program uses the Digital Differential Analyzer (DDA) algorithm to generate 45 degree angles by drawing lines between coordinate points. It includes functions for calculating absolute values and implementing the DDA line drawing method. The main function initializes graphics mode, calls the DDA function twice to draw lines at 45 degree angles, and waits for user input before ending.
