Calculating the usable square feet of up to four rooms

Program Description - This program is designed to calculate the usable square feet of up to four rooms. It asks for an input for the number of rooms and the length and width of each room in feet. It then outputs in a readable format the sqft of each room and the total usable square feet. I also attempted to write the program in C at the bottom.

Analysis - For this program I wanted to be able to calculate the exact number of usable square feet of up to four rooms without asking for unnecessary inputs so I decided to go with an if statement format. I decided I would need the number of rooms, length, and width of each room from the user. The formula for square feet (length * width).

Variables - number_of_rooms, room1_l, room1_w, room1_sqft, room2_l, room2_w, room2_sqft, room3_l, room3_w, room3_sqft, room4_l, room4_w, room4_sqft, total Testing -

test1 2,10,10,12,3 "The square footage of room 1 is 100" "The square footage of room 2 is 36" "The total usable square footage of the house is 136"

test2 1,4,5 "The square footage of room 1 is 20"

test3 6.2,3,24,00001,222 error
