C Program to Calculate Employee's Total Salary

C Program to Calculate Employee's Total Salary
Ready to code a practical solution in C? This program walks you through determining an employee's total monthly salary. You'll quickly see how to accept their basic salary and then apply calculations for tax, House Rent Allowance (HRA), Bonus, Traveling Allowance (TA), and Other Allowance (OA) to get that final figure.
It's a hands-on way to master C's arithmetic and variable handling for real-world financial tasks.

#include <stdio.h> // For input/output

int main() {
    char employeeID[11]; // Employee ID string (up to 10 chars)
    float basicSalary;   // Employee's core monthly earnings
    float tax, hra, bonus, ta, otherAllowance; // Variables for each salary component
    float totalSalary;   // The final computed salary

    // Get Employee ID from user
    printf("Input the Employee's ID (Max. 10 chars): ");
    scanf("%s", employeeID);

    // Get Employee's Basic Salary
    printf("Input the basic salary for the month: ");
    scanf("%f", &basicSalary);

    // Calculate each component based on basicSalary percentages
    tax = 0.10 * basicSalary;  
    hra = 0.17 * basicSalary; 
    bonus = 0.07 * basicSalary; 
    ta = 0.08 * basicSalary;          
    otherAllowance = 0.10 * basicSalary;

    // Compute Total Salary using the specified formula
    // Total salary = (basic salary - tax) + HRA + Bonus + TA + Other Allowance
    totalSalary = (basicSalary - tax) + hra + bonus + ta + otherAllowance;

    // Display the comprehensive salary details
    printf("\n--- Employee Salary Details ---\n");
    printf("Employees ID = %s\n", employeeID);
    printf("Basic Salary = U$ %.2f\n", basicSalary);
    printf("Total Salary = U$ %.2f\n", totalSalary); 

    return 0; // Signals successful program execution
}

Test Data & Expected Output:
Let's run through an example to illustrate the calculation.

Input:
Input the Employee's ID (Max. 10 chars): EMP001
Input the basic salary for the month: 75000

Expected Output:
--- Employee Salary Details ---
Employees ID = EMP001
Basic Salary = U$ 75000.00
Total Salary = U$ 99000.00
(How it gets there: Tax=7500, HRA=12750, Bonus=5250,
TA=6000, Other=7500. Total = (75000-7500)+12750+5250+6000+7500 = 99000)

How This C Program Works
This program efficiently processes an employee's details to calculate their overall monthly pay.
Variables: We use a char array for the employee ID and float variables for all financial values (basicSalary, tax, hra, bonus, ta, otherAllowance, totalSalary). Using float is crucial for handling decimal amounts accurately.

User Input (scanf): The program first prompts for and reads the employee ID and then their basic salary.

Calculations: Each allowance or deduction (like tax or HRA) is determined by multiplying the basicSalary by its specific percentage (e.g., 10% is 0.10). These individual figures are then combined according to the provided formula to derive the totalSalary.

Displaying Results (printf): Finally, the program prints out the employeeID, basicSalary, and the calculated totalSalary. The %.2f format specifier is vital here, ensuring all currency amounts are neatly displayed with two digits after the decimal point.

This demonstrates core C skills: managing different data types, performing precise percentage calculations, and presenting formatted financial output.

Conclusion
You've just built a robust C program for calculating employee salaries! This experience is fantastic for solidifying your understanding of input processing, percentage-based calculations, and getting formatted results just right. It's a key step in applying your C knowledge to practical, real-world data tasks.
