Copy the lab$5\_$part$1.$c program to a new file, lab$5\_$part$2.$c$,$ to use in this part.We will generate random values, but they should be limited to $0,1,2,$ or $3.$ To do this, think of a way to map the random value to a small value; there are many ways to do this, however, the way you choose must be reproducible. That is$,$ if it maps value X to the value $2,$ it should do that every time the value is X$.$ Create a function that accomplishes random number generation and mapping: the function should return a single integer that is a random value of $0,1,2,$ or $3.$ It does not need any inputs. To verify that it works, have your program print about $20$ from it$.$ If your program gives you values like $-1$ or $4,$ you know you have a problem. Also, if it never generates one of the values $(0,1,2,$ or $3),$ then there is a problem.
