### C program to enter basic salary and calculate gross salary of an employee

``` C program to enter basic salary and calculate gross salary of an employee 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. 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. 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. #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; } ```
