C Programs

     Hello, dear friend here is what you want in the learning phase of C programming language. Here, I have placed some simple and basic C program which will provide you the understanding of how to initiate a C program. Every weak I will add more c programs with additional features of structured programming language. Like next programs would contain the logic of decision control  structure (For example - If, If-else and If-else nested). These programs will work best in Turbo C and Turbo C++ environment. If you like my content please also subscribe to my blog so can receive my all updates in your mail. You can subscribe by putting your email in the bottom input field named Follow by Email. If you have any problem in these programs please let me know in the comments or you can join my facebook group https://www.facebook.com/groups/conceptofprogramming

     1. Write a program to find out gross salary of an employee whose dearness allowance is 30% and house rent allowance is 20%. Employee’s basic salary will be inserted by keyboard.

#include<stdio.h>

#include<conio.h>

void main()

{

clrscr();

int basic_salary,da, hra;

int gross_salary;

printf("Enter the basic salary of Employee=");

scanf("%d",&basic_salary);

da=(30 * basic_salary)/100;

printf("Dearness allowance is %d\n",da);

hra=(20 * basic_salary)/100;

printf("House rent allowance is %d\n",hra);

gross_salary=(basic_salary+da+hra);

printf("The gross salary of Employee is %d",gross_salary);

getch();
