        billpay=100*1.20+(units-100)*2;
      else if(units>300)
        billpay=100*1.20+200 *2+(units-300)*3;
        
         }   

   
}
class ComputeElectricityBill

CS8461- OPERATING SYSTEMS LABORATORY-Write C programs to simulate UNIX commands like cp, ls, grep, etc.

Write C programs to simulate UNIX commands like cp, ls, grep, etc. x Before seeing the program you have to learn about what is the meaning of the following commands. cp - copy- it is used to copying contents from one file to another file. Syntax: cp Source Destination ls -list- its used to list all file names in the directory. Syntax: ls grep- The grep filter searches a file for a particular pattern of characters, and displays all lines that contain that pattern. Syntax: grep [options] pattern [files] Options Description -c : This prints only a count of the lines that match a pattern -h : Display the matched lines, but do not display the filenames. -i : Ignores, case for matching -l : Displays list of a filenames only. -n : Display the matched lines and their line numbers. Below code is included code of  both cp & ls command. Program: #include<stdio.h> #include<stdlib.h> #include<dirent.h> #define D...

CS8382-OBJECT ORIENTED PROGRAMMING LABORATORY Develop a java application with Employee class with Emp_name, Emp_id, Address, Mail_id, Mobile_no as members. Inherit the classes, Programmer, Assistant Professor, Associate Professor and Professor from employee class. Add Basic Pay (BP) as the member of all the inherited classes with 97% of BP as DA, 10 % of BP as HRA, 12% of BP as PF, 0.1% of BP for staff club fund. Generate pay slips for the employees with their gross and net salary. PROGRAM: import java.util.Scanner; class Employee{ String Emp_name; int Emp_id; String Address; String Mail_id; int Mobile_no; void display(){ System.out.println(Emp_name); //Syetem.out.println(Address); System.out.println(Emp_id); System.out.println(Mail_id); System.out.println(Mobile_no); } } class Programmer extends Employee{    int BP;  /*int  DA= (int) (0.97*BP);  HRA=(int) (0.10*BP);  PF=(int) (0.12*BP);  */ ...
