Question

a. Design the logic for a program that allows a user to enter 12 numbers, then displays them in the reverse order of entry. b. Modify the reverse-display program so that the user can enter any amount of numbers up to 12 until a sentinel value is entered. ( I really could use more of a pseudocode rather than actual code. also an explanation of each step. The answer I got last time was just c++ code that including a few things we havent even covered in my class yet. )

Answer 1

Below we will just look at the pseudo code to do it

a) We need 12 numbers and store them , then show them in reverse order.

1) int x[12] //declare an array to store 12 elements

2) int number // declare a integer to hold value entered by user

3) do for i =0 to 11 step 4 //we need a for loop to ask user to enter values and loop till 11 as we need 12 values

4) x[i] = number // here in our code we can use printf and scanf to ask user to enter number and scan that value in number and whats shown here is store that number in array.

5) end for //loop ends.

6) do for i = 11 to 0 step 7 // loop from last index to first as we need to show data in reverse order.

7) //here use printf to display x[i] value to console.

b) Could you explain more what is exactly required in b part.
