C Program to Calculate Gross Salary

CALCULATE GROSS SALARY OF AN EMPLOYEE USING C PROGRAM

I this C program we learn how to calculate gross salary of an employee by input basic salary according to given condition.
If Basic Salary <= 10000 then HRA = 20% and DA = 70%. 
If Basic Salary is between 10001 to 20000 then HRA = 25% and DA = 80%. 
If Basic Salary > 20000 then HRA = 30% and DA = 90%.

How to calculate gross salary of an employee using C program.

Example:

 Input :
 Input basic salary of an employee : 24000
 Output:
 Gross Salary = 52800

Formula to calculate gross salary of an employee.

A gross salary is a final salary after the addition of DA, HRA and other allowances. Hare DA is Dearness Allowance and HRA is House Rent Allowance.
The formula of DA, HRA and gross salary is.
da = basic_salary * (DA/100)
If DA = 70% then da = basic_salary * (70/100). Which can be written as da = basic_salary * 0.7 .

hra = basic_salary * (20/100)
If HRA = 20% then da = basic_salary * (70/100). Which can be written as hra = basic_salary * 0.2 .

gross_salary = basic_salary + hra +da.

Algorithm to Calculate Gross Salary:

 Step 1: Start
 Step 2: Read basic salary of an employee
 Step 3: Check if basic_salary <= 10000 then hra = basic_salary * 0.2 and da = basic_salary * 0.8.
 Step 4: Similarly check other condition and compute hra and da.
 Step 5: Calculate gross salary by using formula gross_salary = basic_salary + hra + da.
 Step 6: Print gross salary.
 Step 7: End

Here we learn, how to calculate simple interest by using C language.

/* C Program to Calculate Gross Salary of an Employee */
#include <stdio.h>
int main()
{
	float basic_salary, hra, da, gross_salary;
	clrscr();
        // Input basic salary of an employee 
	printf("\n Enter the Basic Salary of an Employee  :  ");
  	scanf("%f", &basic_salary);
	// Calculate DA and HRA according to specified condition
  	if (basic_salary <= 10000)
  	{
  		hra = basic_salary * 20 / 100;  // or hra = basic_salary * 0.2 
		da = basic_salary * 70 / 100;  // or da= basic_salary * 0.7    	
  	} 
        else if (basic_salary <= 20000)
  	{
  		hra = basic_salary * 0.25;
	  	da = basic_salary * 0.8;  	
  	}
  	else
  	{
	   	hra = basic_salary * 0.3; 
	   	da = basic_salary * 0.9;
	}
        // Calculate gross salary 
	gross_salary = basic_salary + hra + da;
	// Print the gross salary
	printf("\n The gross salary  =  %.2f", gross_salary); 
	return 0;
}

Note: Here %.2f is used to print the gross salary only up to two decimal places because of money format. Normally %f is use to print fractional values up to six decimal places.

 OUTPUT:

 Enter the Basic Salary of an Employee : 24000
 The gross salary = 52800.00
