Caterpillar Eating Leaf - Computer Graphics Lab Animation in C

This is a CG lab program in C using graphics.h library to animate a caterpillar eating a leaf. As it eats, the caterpillar (or worm) should grow proportionally in size. The leaf should also be reduced in size. The program is given below:
 The ouput is:




The program is:
