this is a c++ question. please help me out.A painting company has determined that for every 8 square meters of wall space, one litre of paint and 1.5 hours of labour will be required. The company charges R55 per hour of labour. You have been tasked to write a program that allows the user to enter the square metres of wall space for a number of painting jobs and the price of the paint per litre used for each job. The program should then display the following data for each job:
 The number of litres of paint required
 The hours of labour required
 The cost of the paint
 The labour charges
 The total cost of the paint job.
The program has the following functions:
 void inputAndValidate function that have two reference parameters, namely one
parameter for the wall space in square metres (thus of type double), and the other for the price of the paint per litre (also of type double). This function reads values from keyboard. The function does not accept a value of less than R20 per litre for the price of the paint, and it uses a do...while loop to display a message until the user enters a value greater than or equal to R20 for the price of the paint per litre.
 void determineLabourAndPaint with three parameters: one value parameter to supply the wall space; and two reference parameters for the hours of labour and litres of paint required which should be returned to the main function.
ITCP112 – Take Home Assessment S1 2020 | V1.0 Page 4 of 5-void determineCost with five parameters: three value parameters to supply the hours of labour, litres of paint required and the price of the paint per litre; and two reference parameters for the cost of the labour and the cost of the paint. Remember that the company charges R55 per hour of labour.
 main function containing a for loop going from 1 to NR_JOBS to do the following:
o Call all the functions
o Determine the total cost of the labour and the cost of the paint for each painting job o Display the data for each painting job, i.e.
 The number of litres of paint required  The hours of labour required
 The cost of the paint,
 The labour charges
 The total cost for the paint job
Declare a global constant NR_JOBS and assign the value 6 to it.
Hint: The number of litres of paint required is calculated by dividing the wall space by 8, and rounding this number up, i.e. if 22.3 litres of paint is required, 23 litres of paint should be purchased. The hours of labour required are calculated by dividing the wall space by 8 and multiplying it by 1.5.
