Time	Narration
00:01	પર્લમા if and if-else conditional statements પરનાં સ્પોકન ટ્યુટોરીયલમાં સ્વાગત છે.
00:07	આ ટ્યુટોરીયલમાં, આપણે આપેલ વિશે શીખીશું;
00:09	if સ્ટેટમેન્ટ અને
00:11	પર્લમા if-else સ્ટેટમેન્ટ
00:12	હું વાપરી રહ્યી છું ઉબુન્ટુ લીનક્સ 12.04 ઓપરેટીંગ સીસ્ટમ અને પર્લ Perl 5.14.2
00:20	તેમજ હું gedit ટેક્સ્ટ એડીટર પણ વાપરીશ.
00:24	તમે તમારા પસંદનું કોઈપણ ટેક્સ્ટ એડીટર વાપરી શકો છો. .
00:28	તમને પર્લમાં વેરીએબલો અને કમેંટોની સામાન્ય જાણકારી હોવી અનિવાર્ય છે.
00:33	પર્લમાં for અને foreach લૂપ્સ નું જ્ઞાન હોવાથી વધારાના લાભ થશે.
00:40	સ્પોકન ટ્યુટોરીયલ વેબસાઈટ પર સંદર્ભિત સ્પોકન ટ્યુટોરીયલોનો સંદર્ભ લો.
00:45	પર્લ આપેલ કંડીશનલ સ્ટેટમેન્ટ પૂરી પાડે છે -
00:49	if (ઇફ)
00:50	if-else (ઇફ)
00:51	if-elsif-else અને ( ઇફ -એલ્સઇફ -એલ્સ)
00:53	switch (સ્વીચ)
00:54	આ ટ્યુટોરીયલમાં આપણે if અને If-else સ્ટેટમેન્ટ ને આવરી લેશું.
00:59	પર્લમાં ઇફ સ્ટેટમેન્ટ નો ઉપયોગ
01:01	જયારે નિર્દિષ્ટ કન્ડીશન સંતુષ્ટજનક હોય ત્યારેજ કોડ ના ભાગ ને એક્ઝીક્યુટ કરે છે.
01:07	if કન્ડીશન સ્ટેટમેન્ટનું સિન્ટેક્સ આપ્યા પ્રમાણે છે:
01:11	if space open bracket condition close bracket space Open curly bracket
01:19	Enter
01:20	Piece of code semicolon, to be executed when the condition is true
01:25	Enter, Close curly bracket
01:29	The code inside the if statement will be executed only when the condition is true.
01:36	Now let us look at an example of if statement.
01:40	Open the Terminal and type
01:43	gedit conditionalBlocks dot pl space &(ampersand )
01:49	and press Enter
01:52	This will open the conditionalBlocks.pl file in gedit.
01:57	Type the following piece of code as displayed on the screen.
02:02	Here we have specified a condition for if which checks the value of variable count.
02:09	Note the equal to equal to sign here. This is the comparison operator.
02:15	The condition $count equal to equal to 5 is checked against the value of variable count.
02:23	When it is equal to 5, the code within the if block will get executed.
02:28	Now, press ctrl+s to save the file.
02:32	Then switch to the terminal.
02:36	Make sure that you are in the directory in which you have saved your file.
02:41	Type the following to check for any compilation or syntax error -
02:46	perl hyphen c conditionalBlocks dot pl
02:53	and press Enter.
02:55	The following line will be displayed on the terminal window
02:59	conditionalBlocks.pl syntax OK
03:04	As there is no compilation or syntax error, we will execute the Perl script by typing -
03:10	perl conditionalBlocks dot pl
03:14	and press Enter
03:16	The following output will be shown on terminal.
03:19	I am inside if statement
03:23	Switch back to gedit
03:26	Alternately, we can write the above if statement as-
03:31	print space double quotes I am inside if statement slash n close double quotes space if open bracket dollar count space equal to equal to space 5 close bracket semicolon.
03:57	Now, let us look at if-else statement.
04:01	This statement is used when user wants to execute
04:06	one piece of code when the condition is true and
04:09	another piece of code when the condition is false
04:13	The syntax for if-else condition is as follows -
04:17	if space open bracket condition close bracket space open curly bracket Press Enter.
04:27	piece of code semicolon
04:29	to be executed when if condition is true,
04:32	Press Enter
04:34	close curly bracket space else space open curly bracket Enter
04:41	another piece of code semicolon
04:43	to be executed when if condition is false
04:47	Press Enter close curly bracket
04:51	Now again, go to the conditionalBlocks.pl file which we have already created in gedit.
04:58	Assign 4 to count variable then at the end of the if block type space
05:07	else
05:09	space open curly bracket press Enter
05:14	print space double quotes I am inside else statement slash n close double quotes semicolon
05:30	Press Enter and close curly bracket.
05:34	Here, 4 is assigned to variable $count.
05:38	As the value of count variable does not match 5,
05:43	the code within the if block will not get execute
05:47	instead the code within the else block will get execute.
05:52	Now press Ctrl+S to save the file.
05:56	Now switch to terminal.
05:59	and type perl hyphen c conditionalBlocks dot pl to check for any compilation or syntax error
06:11	now, press Enter
06:13	The following line will be displayed on the terminal
06:17	conditionalBlocks.pl syntax OK
06:20	As there is no compilation or syntax error, we will now execute the Perl script.
06:27	Type perl conditionalBlocks dot pl
06:33	and press Enter
06:35	The following output will be shown on terminal.
06:39	I am inside else statement
06:44	Let us summarize.
06:46	In this tutorial, we have learnt -
06:49	if and
06:50	if-else conditional statements in Perl
06:53	using sample programs.
06:55	Here is assignment for you -
06:57	Print “It is an open source language”
07:01	when the variable declared has value 'Perl'
07:04	otherwise print “It's a proprietary language”
