write a C$++$program that takes three integers from the user in variables num$1,$ num$2,$ and num$3.$ Then assigns pointers ptr$1$ to the address of num$1,$ ptr$2$ to the ad of num$2$ and ptr$3$ to the address of num$3.$ Pass the three pointers to a function called min$\_$max that finds the minimum and maximum of the contents of the variables pointed at by three pointers. The function should return an array of size two containing the maximum and minimum elements.
