The pseudo code would be as follows (you figure out the syntax) 1) Prompt the user to enter a number 2) If entered number is alpha, quit program after displaying message that the user ended the program. 3) Otherwise, find Modulo 2 of the entered number. This is a fancy way of saying "find the remainder when the number is divided by 2) 4) If Modulo 2 is zero, the number is even, otherwise odd 5) Display message showing if the entered number was Even or Odd 6) Branch back to step 1
cho "Enter A Number :" read n r=n s=0 rem=0 while [ $n -gt 0 ] do rem=$(($n%10)) s=$(($s+$rem*$rem*$rem)) n=$(($n/10)) done if [ $r -eq $s ] then echo "The Number is Avogadro" else echo "The Number is Not Avogadro" fi
