Write a C program to input basic salary of an employee and calculate gross salary according to given conditions.

Basic Salary <= 10000 : HRA = 20%, DA = 80%

Basic Salary is between 10001 to 20000 : HRA = 25%, DA = 90%

Basic Salary >= 20001 : HRA = 30%, DA = 95%

How to calculate gross salary of an employee using if else in C programming. Program to calculate gross salary of an employee using if else in C program. Logic to find gross salary of employee in C program.

**Example**

**Input**

Input basic salary of an employee: 22000

**Output**

Gross salary = 44000

## Required knowledge

Basic C programming, Relational operators, If else

## Logic to find gross salary of an employee

Gross salary is the final salary computed after the additions of *DA*, *HRA* and *other allowances*. The formula for *DA* and *HRA* is

`da = basic_salary * (DA/100)`

If `DA = 80%`

then the statement becomes `da = basic_salary * (80/100)`

. Which can also be written as `DA = basic_salary * 0.08`

. Likewise you can also derive a formula for *HRA*.

Step by step descriptive logic to find gross salary of an employee.

- Input basic salary of employee. Store it in some variable say
`basic_salary`

. - If
`basic_salary <= 10000`

then,`hra = basic_salary * 0.8`

and`da = basic_salary * 0.2`

. - Similarly check basic salary and compute
`hra`and`da`accordingly. - Calculate final gross salary using formula
`gross_salary = basic_salary + da + hra`

.

## Program to calculate gross salary of employee

```
/**
* C program to calculate gross salary of an employee
*/
#include <stdio.h>
int main()
{
float basic, gross, da, hra;
/* Input basic salary of employee */
printf("Enter basic salary of an employee: ");
scanf("%f", &basic);
/* Calculate D.A and H.R.A according to specified conditions */
if(basic <= 10000)
{
da = basic * 0.8;
hra = basic * 0.2;
}
else if(basic <= 20000)
{
da = basic * 0.9;
hra = basic * 0.25;
}
else
{
da = basic * 0.95;
hra = basic * 0.3;
}
/* Calculate gross salary */
gross = basic + hra + da;
printf("GROSS SALARY OF EMPLOYEE = %.2f", gross);
return 0;
}
```

**Note:** `%.2f`

is used to print the gross salary only up to two decimal places. You can also use `%f`

to print fractional values normally up to six decimal places.

Output

Enter basic salary of an employee: 22000 GROSS SALARY OF EMPLOYEE = 49500.00
