C++ program for Password input and check

C++ program to input and check a given password. if user input a correct password then program to add two number will be executed and a user input a wrong password. A message "Wrong password" would appeared on the screen and terminates the proram.

#include<iostream.h>
#include<conio.h>
main()
{
clrscr();
for (int i=1;i<=5;i=i+1) // start, condition, increment
{
int a,b,c,x;
cout << "enter your password here";
cin >> x ;
if (x==1)
{\
cout <<"enter first number";
cin >> a;
cout <<"enter second number";
cin >> b;
c=a+b;
cout << c <<endl;
}
else
{
cout << "wrong password";
break;
}
}
getch();
}

Inheritance In C++

C++ program to demonstrate inheritance :
#include<iostream.h>
#include<conio.h>
class demo1 // base class
{
public :
void hello()
{
cout << "hello FROM DEMO1" <<endl;
}
};

class demo2 : public demo1 // derived class
{
public :
void hi()
{
cout << "hi FROM DEMO2" <<endl;
}
};

main()
{
clrscr();
demo2 d2;
d2.hello();
d2.hi();
getch();
}

Function Overloading in C++

Function overloading : two or more than two function in a program with same name but must be different in parameters.
#include<iostream.h>
#include<conio.h>
class demo
{
public :
void add()
{
int a,b,c;
cout <<"enter any number";
cin >> a;
cout <<"enter any number";
cin >>b;
c=a+b;
cout <<c <<endl;
}

void add(int a,int b)

{
int c;
c=a+b;
cout << c <<endl;
}
};

main()
{
clrscr();
int a,b;
cin >> a;
cin >> b;
demo d1;
d1.add();
d1.add(a,b);
getch();
}

// Here in above program there are two add fuctions. One is of without parameters
// and second one is with parameters.

File Handling in C++

File handling : to store data in a text/data file
Writing data to a text file

#include<iostream.h>
#include<conio.h>
#include<fstream.h> // file stream

main()
{
clrscr();
char name[10];
int salary;
ofstream f("unique"); // output file stream is a class name

for (int i=0; i<=4; i++)
{
cout <<"enter name :";
cin >> name;

cout << "enter salary :";
cin >> salary;
f<< name << "\t" << salary<<endl ;
}
getch();
}

// do the following things
/*
1 run the program
2 input some data
3 click file menu > dos shell
4 type the follwing command at dos prompt
type unique
it will display contents of the unique file.
*/

Exit() function in C++

exit function : is terminates entire program. Here it is used in for loop when the value of i is eqauls to 100 then exit(0) will be executed and the program will be terminated.

#include<iostream.h>
#include<conio.h>
#include<process.h> // requires to include for exit() function
main()
{
clrscr();
for (int i=1;i<=100; i++)
{
cout << i <<endl;
if (i==30)
exit(0); // it will termiate entire program
}
cout << "hello" <<endl; // this statement will never execute.
getch();
}

Default Argument Function in C++

default argument function : In this program function add have two parameters and one of them is default argument and has fix value 10. if this argument is passed when calling this function default value of the function will be omited. If this value is not passed then default value
is used as a function argument.

#include<iostream.h>
#include<conio.h>
class demo
{
public :
void add(int a,int b=10) // value of b is default.
{
int c=a+b;
cout << c <<endl;
}
};

main()
{
clrscr();
demo d1;
d1.add(20); // value of b will be 20 and default value if omited.
d1.add(); // value of b will be 10 it means default value is used.
getch();
}

Destructor in C++

destructor : is a member function of a class. it has same name as a class.
followed by a tilde sign ~ it does not have return type (neither int nor void) . it automatically
get executed when object is destroyed.
#include<iostream.h>
#include<conio.h>
class student // student is a class
{
public :
~student() // destructor
{
cout <<"Thanx for using this program" <<endl;
}
};

main()
{
clrscr();
student s1; // s1 is an object
getch();
}

Constructor in C++

// constructor : is a member function of a class. it must have same name
// as a class. it does not have any return type neither int nor void.
// it automatically get executed when object is created. it is used to
// initialize variables.

#include<iostream.h>
#include<conio.h>
class demo
{
public :
int a,b;
demo() // constructor
{
a=10;
b=20;
}

void add()
{
int c=a+b;
cout << c <<endl;
}
};

main()
{
clrscr();
demo d1;

// here object is created d1 of demo class and constructor get called automatically no need to

//call it explicitly.
d1.add();
getch();
}

IF condition in C++

IF condition : condition is formed after if keyword in a bracket.
if condition is satisfies then only statement within if block will be executed, if condition fails then statement within IF block will not be executed. if there is only one statement within if block then {} bracket can be omited if there are more than one statement within if block then statements of if block must be in {} brackets. If condition is formed using relational operators relational operators :

#include<iostream.h>
#include<conio.h>
main()
{
clrscr();
int a; // variale declaration
cout <<"enter any number";
cin >> a;

if (a>100)
{
cout << "Hello" <<endl;
}

if (a<100)
{
cout <<"hi" <<endl;
}

if (a==100)
{
cout <<"bye" <<endl;
}

if (a!=100)
{
cout <<"Unique" <<endl;
}

getch();
}

The above program demonstrates if condition using various relational operators

C program to add two given numbers

In C language how to add two given integer numbers I will show you this by a simple example.It will add two integer values. Every C program must have a main() function. then your program will be in starting curly bracket { and } ending curly bracket. Here we want to add two numbers a and b and result of addition will be stored in c. So here we declare three integer variables a,b & c. clrscr() function is a clear screen function that will clears the screen. printf() function will print a message "enter any number" on the screen to the user to input a number from the keyboard. scanf() function is used to input a value from the keyboard. When this statement is executed then user has to input a value from the keyboard. Value input by the keyboard will be stored in variable a. Same way value of b is to be stored into variable b. In scanf() function, we have used %d format string. %d is for integer means we have to input a integer from the keyboard. other format string are as follows that can be used in the program.
Format Strings:

%d - integer

%f - float

%c - character

Then we come to the statement c=a+b. This statement will add the value of a and b and store into variable c. then printf() statement will print the value of c variable on the screen. Here + is an arithmetic operator. More arithmetic operators can be used such as - (subtract), * (Multiply), / (Divide), % (Mod or Remainder). getch() statement is a get character statement. It pause the output until user presses a key from the keyboard.

#include<stdio.h> // standard input output header file
#include<conio.h>
main()
{
int a,b,c;
clrscr();
printf("enter any number");
scanf("%d",&a); // or cin >> a
printf("enter any number");
scanf("%d",&b);
c=a+b;
printf("%d",c);
getch();
}

C++ program to draw concentric circles

C++ program to generate concentric circles. Here For loop will give radius (i) to circle function and each time it will increment by 5.Delay function will slow down the process to print the concentric circles on the screen. For initgraph() function and circle() function graphics.h header file is used the function initgraph() will convert text mode to graphics mode and closegraph() again converts graphics screen into text mode.In initgraph function third parameter is path of BGI files where graphics files are located. If the graphics driver files are other than this directory than type that path as a third parameter in initgraph() function. Many time we run a graphics program and often a BGI error occurres. It is related to this path of BGI files. Give correct path of BGI files in initgraph() function. If you don't know the path of BGI files then find *.BGI files by find option in winodws and you will be known the correct path.

#include<iostream.h>
#include<conio.h>
#include<graphics.h>
#include<dos.h>

main()
{
clrscr();
int driver,mode;
driver = DETECT;
initgraph(&driver,&mode,"C:\TC\BGI");
for(int i=1;i<=50;i=i+5)
{
circle(100,100,i);
delay(100);
}
getch();
closegraph();

What is an action in Photoshop?

Actions are set of commands that you have to record once and playback any number of times according to your need. Just suppose you have 100 photographs and you want to change the size of all of the photographs so you can create an action of if and apply to all of 100 photographs so you do not need to change the size of all of your photograph manually Photoshop will do it automatically for you. Or we take another example here if you want to make an array of passport photo means picture package so you can once record an action for it and then within a few seconds you will create picture package by using recorded action in future. In short we can say an action is a set of commands that can be played any number of times.

Most of the commands can be included in actions but some are not.

Start Photoshop and then click “Window > Show Actions”. It will display action palette as shown below.
