Question

I need a code that would give me the desired result (the ones in green) from the input (in blue) im using c++. I'm so lost someone please help me. All I know is that there has to be a "while" loop and there is no need for "if" statements.

11. Examples of input and output Here are some examples of input and output for the above program code. Here is an example input from file input1.txt 6 inches 1.5 2.5 2.5 3.5 2.4 1.4 6.2 7.3 For the above example input, here is the expected output. Enter number of pairs of points and units. You entered 6 for the number of squares and inches for units. Enter width and height for square 1 in inches. You entered a width of 1.50 and a height of 2.50 in inches. Square 21: width: 1.5e inches Height: 2.50 inches Area: 3.75 square inches Enter width and height for square 2 in inches. You entered a width of 2.50 and a height of 3.50 in inches. Square #2: width: 2.50 inches Height: 3.50 inches Area: 8.75 square inches Enter width and height for square 3 in inches. You entered a width of 2.40 and a height of 1.40 in inches. Square 3: width: 2.40 inches Height: 1.40 inches Area: 3.36 square inches Enter width and height for square 4 in inches. You entered a width of 4.10 and a height of 1.20 in inches. Square 4: width: 4.10 inches Height: 1.20 inches Area: 4.92 square inches Enter width and height for square as in inches. You entered a width of 6.20 and a height of 7.30 in inches. Square as: Width: 6.20 inches Height: 7.30 inches Area: 45.26 square inches Enter width and height for square #6 in inches. You entered a width of 3.50 and a height of 2.20 in inches. Square #6: width: 3.80 inches Height: 2.20 inches Area: 8.36 square inches The total area of 6 squares is 74.40 square inches.
