this is a C program, please type the code, thanks

4: Compare output A 0/1 Output differs. See highlights below. Input 15 52 Your output Enter wall height (feet): Enter wall width (feet): Wall area: 780.00 square feet Paint needed: 2.21 gallons Cans needed: 4 can(s) Expected output Enter wall height (feet): Enter wall width (feet): Wall area: 780.00 square feet Paint needed: 2.23 gallons Cans needed: 3 can(s) 2.36 LAB*: Program: Painting a wall Output each floating-point value with two digits after the decimal point, which can be achieved as follows: printf("%0.218", yourValue); (1) Prompt the user to input a wall's height and width. Calculate and output the wall's area. (2 pts) Note: This zyLab outputs a newline after each user-input prompt. For convenience in the examples below, the user's input value is shown on the next line, but such values don't actually appear as output when the program runs. Enter wall height (feet): 12.0 Enter wall width (feet): 15.0 Wall area: 180.00 square feet (2) Extend to also calculate and output the amount of paint in gallons needed to paint the wall. Assume a gallon of paint covers 350 square feet. Store this value using a const double variable. (2 pts) Enter wall height (feet): 12.0 Enter wall width (feet): 15.0 Wall area: 180.00 square feet Paint needed: 0.51 gallons (3) Extend to also calculate and output the number of 1 gallon cans needed to paint the wall. Hint: Use a math function to round up to the nearest gallon. (2 pts) Enter wall height (feet): 12.0 Enter wall width (feet): 15.0 Wall area: 180.00 square feet Paint needed: 0.51 gallons Cans needed: 1 can(s)
