1 Assignment : 1 Write following Program using Console Application 1. To find out the total number of an odd digits and even digits within the given number and print the sum of all odd digits and sum of even digits. 2. Write a program to input a number and check whether the number is Armstrong or not. A number is Armstrong number if sum of each digit raised to (total digit) is = number. Example N= 407 (3 digit) = = Write a program to check whether number is Harshad Number or not. Example: n=1729 Sum of digit = 19 Reverse of sum = 91 19*91 = 1729 (Original number). 4. Write a program to find prime number between range of start number and end number. Input Start Number = 1 End Number = 20 Output: Prime numbers from 1 to 20 are Write a program to find out twin prime numbers between 10 to Twin primes are defined to be two consecutive odd numbers, which are prime. e.g.: 11 and 13, 17 and 19 are twin prime numbers. 6. Enter two positive integers and calculate and print out the sum of the products of each pair of digits occupying the same position in the two numbers. Example: If first number is 45 and second number is 534, then output will be 32. (0*5 + 4*3 + 5*4 = 32) If first number is 3445 and second number is 4534, then output will be 64 (3*4 + 4*5 + 4*3 + 5*4 = 64). 7.
