Write a function highLow that takes an integer as an argument and returns whether or not the numberhas alternating “high” and “low” digits. 0 through 4 are “low” digits and 5 through 9 are “high” digits.Your function should return true if the number passed alternates between “high” and “low” digits, andfalse if not. You may assume the number passed is positive. If the number passed consists of a singledigit, highLow should return true.Note: highLow returns true if the number alternates starting with a “high” digit or starting with a “low”digit. What is important is that the digits alternate. For example, both 9292 and 2929 passed to highLowshould return true

Assignment Write a program to calculate n! for a given number n and perform the simple calculator operations. The valid operations of the calculator are: + add - sub * mul I div The program must contain a function fact with one input parameter that returns the factorial of a number, a function add that performs the addition of two numbers, a function sub that performs the subtraction of two numbers, a function mul that performs the multiplication of two numbers, a function div that performs the division of two numbers. The program must also check for bad input data. Make sure when you pass parameters you pass the addresses (not the value). • All function return type must be of type void. • Take inputs in main function. • Pass the addresses of the operands and the address of the result to each function. Output must be displayed as follows: 1: Addition 2: Subtraction 3: Multiplication 4: Division 5: Factorial 6: Quit Enter the choice => 1 Enter two numbers => 2, 3 Sum => 5
