1. first the program should call a function named getcomputerchoice to get the computer's choice in the game. the getcomputerchoice function should generate a random number between 1 and 3. if the random number is 1 the computer has chosen rock, if the random number is 2 the user has chosen paper, and if the random number is 3 the computer has chosen scissors. (hint: return an int from this function and make the function have no arguments). this function is required to be a value returning function (do not make a void function).
