3. You have been contracted to design a system for a smart car. The company installed four laser radars on the car’s corners to use as sensors, for the car to be able to avoid collisions at the rear, and the front. a. Using a flowchart, show the algorithm for the car collision avoidance system.
b. Using any recommended programming language of your choice, write a source code for the car collision avoidance system.

Write a function float computearea(int *v1, int *v2, int shape )that computes the area of fourbasicgeometric entities. the geometric entity will be identified by the argument shape which is 1 for triangle, 2 for square/rectangleand 3 for circle. the arguments v1 and v2 are pointers to the two arguments defining the shape. for circle v1 is a pointer to the diameter of the circle, v2 is null, for rectangle/square, v1 and v2 are pointers to the height and width for triangle v1 is a pointer to the the base and v2 points to the height of the triangle.
