# Question Solved1 AnswerIn C Programming 2.37 LAB*: Program: Painting a wall Program Specifications Write a program to calculate the cost to paint a wall. Amount of required paint is based on the wall area. Total cost includes paint and sales tax. Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. Step 1 (2 pts). Read from input wall height, wall width, and cost of one paint can (doubles). Calculate and output the wall's area to one decimal place using printf("Wall area: %.1f sq ft\n", wallArea);. Submit for grading to confirm 1 test passes. Ex: If the input is: 12.0 15.0 29.95 the output is: Wall area: 180.0 sq ft Step 2 (2 pts). Calculate and output the amount of paint needed to three decimal places. One gallon of paint covers 350 square feet. Submit for grading to confirm 2 tests pass. Ex: If the input is: 12.0 15.0 29.95 the output is: Wall area: 180.0 sq ft Paint needed: 0.514 gallons Step 3 (2 pts). Calculate and output the number of 1 gallon cans needed to paint the wall. Extra paint may be left over. Hint: Use ceil(), included in math.h, to round up to the nearest gallon and convert to an integer. Submit for grading to confirm 4 tests pass. Ex: If the input is: 12.0 15.0 29.95 the output is: Wall area: 180.0 sq ft Paint needed: 0.5142 gallons Cans needed: 1 can(s) Step 4 (4 pts). Calculate and output the paint cost, sales tax of 7%, and total cost. Dollar values are output with two decimal places. Submit for grading to confirm all tests pass. Ex: If the input is: 8.0 8.0 49.20 the output is: Wall area: 64.0 sq ft Paint needed: 0.183 gallons Cans needed: 1 can(s) Paint cost: \$49.20 Sales tax: \$3.44 Total cost: \$52.64

2.37 LAB*: Program: Painting a wall

Program Specifications Write a program to calculate the cost to paint a wall. Amount of required paint is based on the wall area. Total cost includes paint and sales tax.

Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress.

Step 1 (2 pts). Read from input wall height, wall width, and cost of one paint can (doubles). Calculate and output the wall's area to one decimal place using printf("Wall area: %.1f sq ft\n", wallArea);. Submit for grading to confirm 1 test passes.

Ex: If the input is:

```12.0 15.0 29.95
```

the output is:

```Wall area: 180.0 sq ft
```

Step 2 (2 pts). Calculate and output the amount of paint needed to three decimal places. One gallon of paint covers 350 square feet. Submit for grading to confirm 2 tests pass.

Ex: If the input is:

```12.0 15.0 29.95
```

the output is:

```Wall area: 180.0 sq ft
Paint needed: 0.514 gallons
```

Step 3 (2 pts). Calculate and output the number of 1 gallon cans needed to paint the wall. Extra paint may be left over. Hint: Use ceil(), included in math.h, to round up to the nearest gallon and convert to an integer. Submit for grading to confirm 4 tests pass.

Ex: If the input is:

```12.0 15.0 29.95
```

the output is:

```Wall area: 180.0 sq ft
Paint needed: 0.5142 gallons
Cans needed: 1 can(s)
```

Step 4 (4 pts). Calculate and output the paint cost, sales tax of 7%, and total cost. Dollar values are output with two decimal places. Submit for grading to confirm all tests pass.

Ex: If the input is:

```8.0 8.0 49.20
```

the output is:

```Wall area: 64.0 sq ft
Paint needed: 0.183 gallons
Cans needed: 1 can(s)
Paint cost: \$49.20
Sales tax: \$3.44
Total cost: \$52.64```
