Print instructions explaining how to operate the calculator Allow the user to continue entering calculations until they quit the program Allow the user to perform the following operations: - add ( + ) should add to doubles - subtract ( - ) should subtract to doubles - multiply ( * ) multiply two doubles - divide ( / ) divide two doubles, do not allow division by zero - power ( ^ ) a double and an integer, calculate the double raised to the integer. zero and negative exponents should work. - exponential ( e ) raise the constant e to the power of the integer provided. zero and negative exponents should work. (you must define the constant) - factorial ( ! ) given an integer, calculate the factorial. store your result as a long - random range ( r ) given two integers, generate a random integer between the two integers (inclusively). Be sure the lower bound is less than the upper bound - sum range ( s ) calculate the sum of consecutive integers between two given integers (inclusively) - round ( ~ ) given a double, round to the nearest integers - roundup ( ' ) given a double, round to the nearest integers - rounddown ( _ ) given a double, round to the nearest integers - minimum ( < ) given two doubles, determine the lesser - maximum ( > ) given two doubles, determine the greater Allow the user to input the calculation all at once (examples below) + 3 4 / 4.3 2.3 ^ 3.1 2 r 5 10 Your code must meet the following technical specifications - use at least two variables of different types - no global variables allowed - use a constant, global constants are ok - use at least one if or if else statement - use at least one switch statement - use at least one for loop - use at least one while or do while loop - use at least three functions with prototype. - at least one must return a value - at least one must take input
