AIM: To write a C program for Line Drawing Using Bresenham Algorithm.
Step 1 : Start the program. Step 2 : Declare the necessary variables. Step 3 : Initialize the graph using dx, dy, gd, gm. Step 5 : Similarly, absolute values to dx, dy.
ul
Step 6 : put pixel and set 15 to pixel position.
.c
Step 4 : Assign the values of x1, y1 to x,y respectively.
Step 7 : Using do-while loop, put e,x,y,I values.
