1. Write a C++ program to print all even numbers between two numbers (entered by the user) by making a user-defined function. Display the answer in main () function. [Estimate Finish Time: 15 minutes) 2. A program is required to prompt for and accept a time and compute the number of seconds elapsed since midnight. The time should be entered in the format HH:MM:SS. Output sample: Please enter your elapsed time (in HH:MM:SS format) = 00:02:44 Elapsed time in seconds = 164 seconds [Estimate Finish Time: 15 minutes)1. Write a program that checks if a given array is a Palindrome. Palindrome is a number that remains the same when its digits are reversed. Like 16461, for example. Output sample: Microsoft Visual Studio Debug Console Enter a palindrome number: 12321 12321 is a palindrome number. Microsoft Visual Studio Debug Console X Enter a palindrome number: 13221 13221 is not a palindrome number. Microsoft Visual Studio Debug Console X Enter a palindrome number: 123321 123321 is a palindrome number. Microsoft Visual Studio Debug Console 0 X Enter a palindrome number: 123231 123231 is not a palindrome number. [Estimate Finish Time: 15 minutes)2.
