You want to connect your small company network to the internet. Your ISP provides you with a single IP address that is to be shared between all hosts on your private network. You do not want external hosts to be able to initiate connections to internal hosts. What type of network address translation (NAT) should you implement?'

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.
