Let Us C Chapter 1 Exercise I-a

Q. Ramesh's basic salary is input through the keyboard. His dearness allowance is 40% of basic salary, and house rent allowance is 20% of basic salary. Write a program to calculate his gross salary.

I'm doing these exercises so that I have something to do with C. I didn't use doubles or %.2f  because they haven't been taught in chapter 1.

Code:

#include <stdio.h>

main()
{
    float BasicSalary,DAllowance,HRAllowance,temp;

    printf("Enter Ramesh's Basic Salary: ");
    scanf("%f",&BasicSalary);

    /**Calculate 1% of salary*/
    temp=BasicSalary/100;

    /**Assign Dearness Allowance (40%) and House Rent Allowance (20%)**/
    DAllowance=temp*40;
    HRAllowance=temp*20;

    /**display**/
    printf("Ramesh's Dearness Allowance is: %f\n",DAllowance);
    printf("Ramesh's House Rent Allowance is: %f\n\n",HRAllowance);

    printf("Ramesh's Total Salary is: %f\n",BasicSalary+DAllowance+HRAllowance);

    return 0;
}

Following are simplifications of this program:

#include <stdio.h>

main()
{
    float BasicSalary,GrossSalary;

    printf("Enter Ramesh's Basic Salary: ");
    scanf("%f",&BasicSalary);

    GrossSalary=BasicSalary+(BasicSalary*.6);

    printf("Ramesh's Gross Salary is= %f",GrossSalary);
}


OR

#include <stdio.h>

main()
{
    float BasicSalary,GrossSalary;

    printf("Enter Ramesh's Basic Salary: ");
    scanf("%f",&BasicSalary);

    GrossSalary=BasicSalary*1.6;

    printf("Ramesh's Gross Salary is= %f",GrossSalary);

}
