#include<stdio.h>
#include<conio.h>
int main()
{
    int num,rev=0,i,j;
    printf("\nEnter number : ");
    scanf("%d",&num);
    while(num!=0)
    {
        i=num%10;
        rev=rev*10+i;
        num/=10;

5. Write a shell script which will accept a number and display first n prime numbers as output. Complete code of the program read -p "Enter the value of n (or range) " n echo "The prime numbers are: " m=2 while [ $m -le $n ] do i=2 flag=0 while [ $i -le `expr $m / 2` ] do if [ `expr $m % $i` -eq 0 ] then flag=1 break fi i=`expr $i + 1` done if [ $flag -eq 0 ] then echo $m fi m=`expr $m + 1` done Interpreting the prime.sh file and executing it in terminal tkanu025@hp:~/lab_solutions$ chmod +x prime.sh tkanu025@hp:~/lab_solutions$ ./prime.sh Output Previous Program Next Program gtu os lab manual, os GTU Practical, operating system Programs, Operating system shellscript programs, Gtu study material 3140705, OS 314070...

Creating Objects

Image
As we have seen earlier a class provides the blueprint for objects. A class creates a logical framework that defines the relationship between its members. An object in Java is essentially a block of memory that contains space to store all the instance variables. It can also be considered as a variable. Obtaining objects of a class is a two-step process   Declaring  variable of the class type Acquiring an actual, physical copy of the object and assign it to that variable. Box mybox = new Box(); The above line creates an object of the Box class. Here it combines two statements into a single statement. It can be rewritten as - Box mybox; //declare reference to object mybox = new Box(); //allocate a box object Here, first line declares mybox as a reference to an object of type Box . After this line executes, mybox contains the value null. Any attempt to use mybox at this point may cause a compile-time error. S...
