Man Rowing Boat Animation - Computer Graphics Lab Animation Experiment

This is a computer graphics lab program. This is an animation program. The experiment is to animate a scene of a man rowing boat in a river on a rainy day. The man wears a hat also. The program uses the graphics library graphics.h. This program works well in the turbo c compiler with Borland graphics interface (BGI). The output of the program is as follows:

The program is as follows:

#include<stdio.h>
#include<graphics.h>
#include<math.h>
#include<stdlib.h>
