Write a C++ program to compute the surface-area of a cylinder, given the radius (R) and the height (H). The program must ask the user to enter R and H. It then prints the surface-area with a proper message in the main program. Define a function to compute the surface-area and let main() call it. Clearly show the function prototype. This function takes the radius R and height H as parameters and returns the surface area. The formula for computing the surface-area of a cylinder is 2πR(H + R), where ? = 3.141 Write a function called isValidLength that takes an integer number and returns true if the number has a valid length and false otherwise. Valid- length is determined by finding number length. If the length is at least 3 digits and at most 5 digits, then the number has a valid length. For example, the number 324 is valid because it's 3 digits long and the number 22 is invalid because it’s 2 digits long. Write a function called isValidDigits that takes an integer number and returns 1 if the number represents valid code and 0 otherwise. Valid- digits is determined according to the following rule: All the digits must be between 1 and 5 (inclusive). For example, the number 324 is valid because all digits are between 1 and 5. However, the number 3256 is not valid because it consists of the digit 6 which is not in the range 1 to 5. 5. Write a function called isValidOddDigits that takes an integer number and returns 1 if the number represents valid code and 0 otherwise. Valid code is determined according to the following rule: The sum of the digits must be odd number.
