Explanation:
- Pass-by-Value (
calculateGrossSalaryByValue):- Function Definition:
double calculateGrossSalaryByValue(double basicSalary) - This function receives a copy of the
basicSalary. - It calculates the HRA (House Rent Allowance) and DA (Dearness Allowance) based on the salary brackets:
<= 10000: HRA = 20%, DA = 80%<= 20000: HRA = 25%, DA = 90%> 20000: HRA = 30%, DA = 95%
- It then computes the gross salary and returns it.
- Function Definition:
- Pass-by-Reference (
calculateGrossSalaryByReference):- Function Definition:
void calculateGrossSalaryByReference(double basicSalary, double &grossSalary) - This function receives the
basicSalaryand a reference togrossSalary. - It calculates the HRA and DA similarly but stores the result directly in the
grossSalaryreference. - The
grossSalaryvariable in themainfunction is updated with the computed value.
- Function Definition:
- Main Function (
main):- The program prompts the user to input the basic salary.
- It calculates the gross salary using both methods and prints the results.
