A number is called palindrome, if it reads the same on reading from both left and right. Thus, 121 is a palindrome, but 123 is not. Because, on reading from the right, it is 321 and not 123. The steps followed are, get the number to be checked. reverse the number. compare with the given number. conclude. The program would be as follows. The Program /palindrome 25/08/2013 #include<conio.h> #include<iostream.h> class dom { int dgt,dum; int flag; public: void get() { clrscr(); cout<<"enter the digit:"; cin>>dgt; dum=dgt; flag=0; } void check(); void disp() { if (flag==1) cout<<endl<<"palindrome"; else cout<<endl<<"not palindrome"; } }; void dom::check() { flag=0; int sum=0,w; while (dum!=0) { w=dum%10; sum=sum*10+w; dum=dum/10; } cout<<"reversed:"<<sum; if (sum==dgt) flag=1; }; void main() { clrscr(); dom obj; obj.get(); obj.check...

T he below described is a program that shows how variables are declared in a dynamic manner. We can also initialize these variables dynamically. Hope this would be so simple for you. By trying some another examples, you can master on it.! The program // using simple dynamic initialization of variables #include<iostream.h> #include<conio.h> void main() { clrscr(); int b,c=sizeof("xloi");    //dynamic initialization for 'c' cout<<"\nvalue for b="; cin>>b; int q=b*1.3*c;  //dynamic initialization for 'q' cout<<"q="<<q; getch(); }

T he const key word creates symbolic const ants in Cpp. The values declared as const cannot be modified by the program in any way. So it is a way of declaring const ants throughout the program. The program //using const data type #include<conio.h> #include<iostream.h> const int q=10;    // const are global in nature. void main() { const char w[q]="\nhello\n"; const char e='k'; clrscr(); cout<<q<<w<<e; getch(); }

Hi guys, This is a simple cpp program to check weather a number is amstrong or not. A number is amstrong if the sum of the cubes of the digits of the number is the same number. Thus as a common example we use the number 153. Then, 1^3=1 5^3=125 3^3=27 the total will be 1+125+27=153 ,the same number. In the program, we: input the number to be checked. extract each digits from the number. take cubes. add up. check the result with the given number. display the result. Now try the program given below: //amstrong #include<conio.h> #include<iostream.h> class dom { int dgt,dum,flag; public: void get() { cout<<"Enter the digit:"; cin>>dgt; cout<<"done!"; dum=dgt; } void check(); void disp() { if(flag==1) cout<<"\n Awesome! Amstrong"; else cout<<"\noops! not *_* TRY AGAIN"; } }; void dom::check() { int q,sum=0; while (dum!=0) { q=dum%10; sum=sum+q*q*q; dum=dum/10; } ...

T his program illustrates how to implement the arithmetic operation in an object oriented way. Here we have a class with 2 variables. For each operation an object of this class is created to do the operation instead of declaring such much variables. Therefore, this method is, for a large scale implementation, is quite efficient. so have a try on it. Program: //simple operations in object oriented method #include<conio.h> #include<iostream.h> class dom { int a,b; public: void get() { cout<<"oops..!\nnumbers:"; cin>>a>>b; cout<<"passed"; } void add() { cout<<endl<<"a+b="<<a+b; } void diff() { cout<<endl<<"a-b="<<a-b; } void mult() { cout<<endl<<"a*b="<<a*b; } void div() { cout<<endl<<"a/b="<<a/b; } }; void main() { clrscr(); dom add, mult,diff,div; cout<<"\n+"; ...

We input two sets of matrices and the output is obtained simply adding the curresponding elements of the matrices. A game of simple logic. Program: //matrix #include<iostream.h> #include<conio.h> class dom { int m,n,i,j,a[3][3],b[3][3],c[3][3]; public: void get(); void check(); void disp(); }; void dom::get() { cout<<"enter the order of matrix\n"; cin>>m>>n; cout<<"enter the elements of first matrix\n"; for(i=0;i<m;i++) for(j=0;j<n;j++) cin>>a[i][j]; cout<<"enter the elements of second matrix\n"; for(i=0;i<m;i++) for(j=0;j<n;j++) cin>>b[i][j]; }; void dom::check() { for(i=0;i<m;i++) for(j=0;j<n;j++) c[i][j]=a[i][j]+b[i][j]; }; void dom::disp() { cout<<"the sum of matrix is \n"; for(i=0;i<m;i++) { for(j=0;j<n;j++) { cout<<"\t"<<c[i][j]; } cout<<"\n"; } } void main() { clrscr(); dom...

There are a vast amount of programming language that we are using. Some are designed to accomplish some specific task. Some are for common uses.

OOPs – Object Oriented Programming System Object-oriented programming (OOP) is a programming paradigm that uses “Objects “and their interactions to design applications and computer programs. There are different types of OOPs are used, they are Object Class Data Abstraction & Encapsulation Inheritance Polymorphism Dynamic Binding Message Passing 1) Object : Object is the basic unit of object-oriented programming. Objects are identified by its unique name. An object represents a particular instance of a class. There can be more than one instance of an object. Each instance of an object can hold its own relevant data. An Object is a collection of data members and associated member functions also known as methods. For example whenever a class name is created according to the class an object should be created without creating object can’t able to use class. The class of Dog defines all possible dogs by listing the characteristics and behaviors they can have; the object Lassie is one pa...
