Calculating Gross Salary in C++

Introduction

In this code example, we will calculate the gross salary of an employee named Rajesh. The gross salary is the total salary earned by an employee, including various allowances and benefits.

Key Concepts

Before we dive into the code, let's understand some key concepts:

• Basic Salary: It is the fixed amount of money paid to an employee before any deductions or additions.
• Dearness Allowance: It is an allowance given to employees to cope with the rising cost of living. It is usually calculated as a percentage of the basic salary.
• House Rent Allowance: It is an allowance given to employees to cover their rental expenses. Like dearness allowance, it is also calculated as a percentage of the basic salary.
• Gross Salary: It is the total salary earned by an employee, including the basic salary and various allowances.

Code Structure

#include <iostream>
using namespace std;

int main() {
    // Declare variables
    double basicSalary, grossSalary;
    const double dearnessAllowanceRate = 0.4;  // 40%
    const double houseRentAllowanceRate = 0.2; // 20%

    // Input Rajesh's basic salary
    cout << "Enter Rajesh's basic salary: ";
    cin >> basicSalary;

    // Calculate dearness allowance
    double dearnessAllowance = basicSalary * dearnessAllowanceRate;

    // Calculate house rent allowance
    double houseRentAllowance = basicSalary * houseRentAllowanceRate;

    // Calculate gross salary
    grossSalary = basicSalary + dearnessAllowance + houseRentAllowance;

    // Output the result
    cout << "Rajesh's Gross Salary: " << grossSalary << " units" << endl;

    return 0;
}
