$3.$ Write a C$++$ program that does the following: a$.$ Create a C$++$ file with the name problem$3.$cpp$.$ b$.$ Prompt the user for a positive integer, which represents the number of simulated die rolls. Print "Not playing games." and terminate the program if the user enters an invalid integer. c$.$ Use a loop to simulate n die rolls, where for each die roll, print the roll number and the simulated die roll value. d$.$ After the last die roll, print the total count of ones rolled. Sample run of the program: Enter the number of die rolls: $5$ Roll $1$: $2$ Roll $2$: $3$ Roll $3$: $6$ Roll $4$: $1$ Roll $5$: $2$ Total number of ones rolled: $1.$
