Sure, here is a step-by-step guide to write a program that reads and stores positive numbers in an array and performs a linear search and binary search to find a number provided by the user:

1. Start by declaring the necessary variables and arrays. You will need an integer variable `n` to store the number of elements in the array, an integer variable `k` to store the number to be searched, and an integer array `arr` to store the positive numbers.

2. Prompt the user to enter the value of `n` and read it from the input.

3. Create a loop to read `n` positive numbers from the user and store them in the `arr` array. Make sure to validate that the numbers entered are positive.

4. Prompt the user to enter the number `k` to be searched and read it from the input.

5. Implement the linear search algorithm to find `k` in the `arr` array. Start from the first element and compare it with `k`. If a match is found, print the index of the element. If the end of the array is reached without finding a match, print a message indicating that `k` is not found.

6. Sort the `arr` array in ascending order using any sorting algorithm (e.g., bubble sort, insertion sort, etc.).

7. Implement the binary search algorithm to find `k` in the sorted `arr` array. Set the lower bound `low` to the first index of the array and the upper bound `high` to the last index. Repeat the following steps until `low` is less than or equal to `high`:
- Calculate the middle index `mid` as the average of `low` and `high`.
- If the element at index `mid` is equal to `k`, print the index and exit the loop.
- If the element at index `mid` is greater than `k`, set `high` to `mid - 1`.
- If the element at index `mid` is less than `k`, set `low` to `mid + 1`.

8. If the loop in step 7 completes without finding a match, print a message indicating that `k` is not found in the array.

That's it! You have now implemented a program that reads and stores positive numbers in an array and performs a linear search and binary search to find a number provided by the user.
