Assignment Operators in Hindi

Assignment Operators in Hindi

Assignment Operators के लिए '=' operator का इस्तेमाल किया जाता है |

Assignment Operators पांच प्रकार के होते है |

Operators	For Example	Description
=	a = b	Assignment Operator
+=	a += b or a = a + b	Add Assignment Operator
-=	a -= b or a = a - b	Subtract Assignment Operator
*=	a *= b or a = a * b	Multiply Assignment Operator
/=	a /= b or a = a / b	Divide Assignment Operator
%=	a %= b or a = a % b	Modulus Assignment Operator

Example = (Assignment Operator)

Source Code :

123456<?php
$a = 5;  
$b = $a;
 echo "Value of a : ".$a. "<br />";
 echo "Value of b : ".$b;
?>

Output :

Value of a : 5
Value of b : 5

Example += (Add Assignment Operator)

Source Code :

123456<?php
$a = 5;  
$b = 10;
$a += $b;    // a = a + b; 
 echo "Value of a : ".$a;
?>

Output :

Value of a : 15

Example -= (Subtract Assignment Operator)

Source Code :

123456<?php
$a = 5;  
$b = 10;
$a -= $b;    // a = a - b;
 echo "Value of a : ".$a;
?>

Output :

Value of a : -5

Example *= (Multiply Assignment Operator)

Source Code :

123456<?php
$a = 5;  
$b = 10;
$a *= $b;    // a = a * b;
 echo "Value of a : ".$a;
?>

Output :

Value of a : 50

Example /= (Divide Assignment Operator)

Source Code :

123456<?php
$a = 5;  
$b = 10;
$a /= $b;    // a = a / b;
 echo "Value of a : ".$a;
?>

Output :

Value of a : 0.5

Example %= (Modulus Assignment Operator)

Source Code :

123456<?php
$a = 5;  
$b = 10;
$a /= $b;    // a = a % b;
 echo "Value of a : ".$a;
?>

Output :

Value of a : 5

Logical Operators in Hindi

Logical Operators in Hindi

Logical Operators तीन प्रकार के होते है |

Operators	Description
&&(and)	AND
||(or)	OR
!	NOT

Example for &&(and) Logical Operator

&& operator के साथ दिए हुए दोनों conditions अगर true होते है तो ये true return करता है | '&&' operator के बजाय 'and' को भी लिखा जाता है |

Source Code :

1234567<?php
$a = 5;  
$b = 6;

if(($a < $b) || ($a > $b))
 echo "logic is true.";
?>

Output :

logic is true.

Example for ||(or) Logical Operator

|| operator के साथ दिए हुए दोनों conditions में से अगर एक भी condition true होती को तो ये true return करता है | '||' operator के बजाय 'or' को भी लिखा जाता है |

Source Code :

1234567<?php
$a = 5;  
$b = 6;

if(($a < $b) || ($a > $b))
 echo "logic is true.";
?>

Output :

logic is true.

Example for ! Logical Operator

Program में अगर condition false है तो ! operator से logic true हो जाता है | अगर condition true है तो ! operator से logic false किया जाता है |

Source Code :

1234567<?php
$a = 5;  
$b = 6;

if(!($a > $b))
 echo "logic is true.";
?>

Output :

logic is true.

Comparison Operators in Hindi

Comparison Operators में आठ प्रकार के Operators होते है |

Operators	Description
<	Less than
>	Greater than
<=	Less than or Equal to
>=	Gretaer than or Equal to
==	Equal to
===	Equal to
!=	Not Equal to
!==	Not Equal to

Example for <(Less than)

Source Code :

12345678<?php
$a = 10;  
$b = 6;
if($a < $b)
 echo "a is less than b";
else
 echo "a is not less than b";
?>

Output :

a is not less than b

Example for >(Greater than)

Source Code :

12345678<?php
$a = 10;  
$b = 6;
if($a > $b)
 echo "a is greater than b";
else
 echo "a is not greater than b";
?>

Output :

a is greater than b

Example for <=(Less than or Equal to)

Source Code :

12345678<?php
$a = 10;  
$b = 10;
if($a <= $b)
 echo "a is less than or equal to b";
else
 echo "a is not less than or equal to b";
?>

Output :

a is less than or equal to b

Example for >=(Greater than or Equal to)

Source Code :

12345678<?php
$a = 10;  
$b = 5;
if($a >= $b)
 echo "a is greater than or equal to b";
else
 echo "a is not greater than or equal to b";
?>

Output :

a is greater than or equal to b

Difference between == and ===

Program में दो variables दिए हुए है उन दोनों का data type अलग-अलग है | उसमे से $a की value; integer है और $b की value double है |

== ये operator अपनी values को compare करता है |

=== ये operator अपनी values और उसके data types को compare करता है |

Source Code :

123456789101112131415<?php
$a = 5;     //Integer
$b = 5.0;   //Double

if($a == $b)
 echo "a is equal to b <br />";
else
 echo "a is not equal to b <br />";


if($a === $b)
 echo "a is equal to b <br />";
else
 echo "a is not equal to b <br />";
?>

Output :

a is equal to b 
a is not equal to b 

Difference between != and !==

Program पर दो variables है लेकिन उन दो variables की values same है पर data types अलग-अलग है |

!= ये operator अपनी values को compare करता है |

!== ये operator अपनी values और उसके data types को compare करता है |

Source Code :

123456789101112131415<?php
$a = 5;     //Integer
$b = "5";   //String

if($a != $b)
 echo "a is not equal to b <br />";
else
 echo "a is equal to b <br />";


if($a !== $b)
 echo "a is not equal to b <br />";
else
 echo "a is equal to b <br />";
?>

Output :

a is equal to b 
a is not equal to b
