Design the logic for a program that allows a user to enter 20 numbers, then displays all of the numbers, the largest number, and the smallest.

Logic of the program:

Step 1: START

Step 2: Set Integer data type array variable with size 20.

Step 3: Get input from the user in the array variable.

Step 4: Print the array variable

Step 5: Set integer variable "Maximum" in which we store the array index 0

Step 6: Set integer variable "Minimum" in which we store the array index 0

Step 7: Again set an integer variable "i" to 0

Step 8: Set the while loop and pass condition the variable "i" is less than 20

Step 9: Then, set the if conditional statement and check array[i] is greater than the variable "Maximum" then,

Step 10: Initialize the value of array[i] in the variable "Maximum" i. e., Maximum = array[i]

Step 11: Again set the if conditional statement and check array[i] is less than the variable "Minimum" then,

Step 12: Initialize the value of array[i] in the variable "Minimum" i. e., Minimum = array[i].

Step 13: END the IF condition.

Step 14: Increment in the variable "i" by 1 i. e., i = i+1

Step 15: END the WHILE loop

Step 16: Print the value of the variable "Maximum"

Step 17: Print the value of the variable "Minimum"
