Practical 4. Solve the following :

a. Develop a program for DDA line drawing algorithm.

Code :
import turtle

def draw_dda_line(x1, y1, x2, y2):


dx = abs(x2 - x1)
dy = abs(y2 - y1)
steps = max(dx, dy)
dx /= steps
dy /= steps
x, y = x1, y1

for _ in range(int(steps) + 1):


turtle.setpos(round(x), round(y))
turtle.dot()
x += dx
y += dy

# Example usage
x1, y1 = map(float, input("Enter the value of x1 and y1 (comma-separated):
").split(','))
x2, y2 = map(float, input("Enter the value of x2 and y2 (comma-separated):
").split(','))

turtle.speed(1)
turtle.hideturtle()
draw_dda_line(x1, y1, x2, y2)
turtle.done()
