C Program to Calculate Bonus and Gross Using Basic Salary

Here is a C program that calculates an employee's bonus and gross salary based on their basic salary. The purpose of this program is to demonstrate basic mathematical calculations using C.

Example Program:

#include <stdio.h>

void main() {
  // Declare variables
  float basic_salary, bonus, gross_salary;

  // Get basic salary from user
  printf("Enter basic salary: ");
  scanf("%f", &basic_salary);

  // Calculate bonus
  if (basic_salary <= 10000) {
    bonus = basic_salary * 0.1;
  } else {
    bonus = basic_salary * 0.2;
  }

  // Calculate gross salary
  gross_salary = basic_salary + bonus;

  // Print results
  printf("Bonus: %.2f\n", bonus);
  printf("Gross salary: %.2f\n", gross_salary);
}

Program Output:

Enter basic salary: 5000
Bonus: 500.00
Gross salary: 5500.00

In the above C program, the basic salary is entered by the user and stored in a variable called basic_salary. The program then calculates the bonus using an if-else statement. If the basic salary is less than or equal to 10000, the bonus is 10% of the basic salary. Otherwise, the bonus is 20% of the basic salary.

Finally, the program calculates the gross salary by adding the bonus to the basic salary and prints the results on the screen.

This is a simple example but illustrates the basic concepts of reading input, performing calculations, and printing output in a C program.
