C Program 3: To calculate the gross salary when the basic salary is entered through keyboard

Aim: 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.

Theory: We need to take input from user and then apply the simple formula to calculate the gross salary i.e. gross salary= basic salary+ dearness allowance+ house rent allowance.

Following would be the program code:

//to calculate the gross salary

#include<stdio.h>

#include<conio.h>

int main()

{

    int bs, gs, da, hr;

    printf("Enter the basic salary:");

    scanf("%d", &bs);

    da=40*bs/100; //given that dearance allowance is 40% of basic salaray

    hr=20*bs/100; //given that house rent is 20% of basic salaray

    gs= bs + da + hr; //formula to calculate gross salary

    printf("The gross salary is: %d", gs);

    getch();

    return 0;

}

First we asked the user to enter the basic salary and then take the input using the scanf("%d", &bs); statement. Now, we calculate the dearness allowance using this statement da=40*bs/100; Similary we will calculate the house rent allowance according to the values mentioned in the question and then we would use our main formula to calculate the gross salary  i.e. gs= bs + da + hr;
