1. Compose a C++ for loop that displays the even integer values starting with four and ending with eighteen. Provide all the code needed to execute your answer if it were included as part of a complete program. 2. Compose a C++ while loop that allows the user to enter a number. The number should then be multiplied by 8, and the result assigned to a variable named product. The loop should continue to repeat prompting the user to enter a number, multiplying it by 8 and assigning the product to the variable named product if the value of product is less than 91. 3. Compose the C++ code that prompts the user to enter a number in the range from 23 through 67, validates the input, and then displays the validated entry.
