Question 5
The algorithm, represented using pseudo-code in Figure 4, and the variable table, Table 2, describe a program that outputs an estimate for a particular calculation.
Figure 4
OUTPUT "Enter a number:" INPUT N F = 16.0 IF N >= 1.0 :THEN ::X = N ::WHILE X * X – N > 1.0 AND F – 1.0 > 1.0 DO :::L = X :::X = X ÷ F :::WHILE X * X <= N DO ::::F = F – 0.1 ::::X = L ÷ F :::ENDWHILE ::ENDWHILE ::OUTPUT X :ELSE ::OUTPUT "Not a number greater than or equal to 1" ENDIF

What you need to do
- Write a program for the algorithm in Figure 4.
- Test the program by conducting the tests:
- Test that your program works correctly by entering the number 0.1
- Test that your program works correctly by entering the number 4.1
