| 00:01 | C અને C++ માં સ્ટ્રક્ચર્સ પરના સ્પોકન-ટ્યુટોરીયલમાં તમારું સ્વાગત છે. |
| 00:06 | આ ટ્યુટોરીયલમાં આપણે શીખીશું,
|
| 00:09 | સ્ટ્રક્ચર્સ શું છે?
|
| 00:11 | સ્ટ્રક્ચર્સ જાહેર કરવું. |
| 00:13 | આપણે આ ઉદાહરણ મારફતે કરીશું. |
| 00:16 | આ ટ્યુટોરીયલ રેકોર્ડ કરવા માટે, હું ઉપયોગ કરું છું
|
| 00:19 | Ubuntu Operating System આવૃત્તિ 11.10,
|
| 00:23 | gcc અને g++ કમ્પાઈલર આવૃત્તિ 4.6.1 |
| 00:29 | ચાલો સ્ટ્રક્ચર્સ ના પરિચય સાથે શરૂ કરીએ. |
| 00:32 | એક અથવા વધુ વેરિયેબલ્સ એક નામ હેઠળ જૂથ થયેલ હોય તે સ્ટ્રક્ચર્સ તરીકે ઓળખાય છે. |
| 00:38 | સ્ટ્રક્ચર્સ એક ઓબ્જેક્ટમાં અલગ અલગ ડેટાને ગ્રુપ કરવા માટે વપરાય છે. |
| 00:43 | તે compound data-type તરીકે ઓળખાય છે. |
| 00:45 | તે સંબંધિત માહિતીને એકસાથે જૂથ કરવા માટે વપરાય છે. |
| 00:49 | હવે આપણે, |
| 00:50 | સ્ટ્રક્ચર જાહેર કરવા માટેનું સીન્ટેક્ષ જોઈશું. |
| 00:53 | અહીં કીવર્ડ સ્ટ્રક્ટ કમ્પાઇલરને કહે છે કે સ્ટ્રક્ચર જાહેર કરવામાં આવેલ છે.
|
| 00:59 | strcut_name એ સ્ટ્રક્ચરનું નામ છે.
|
| 01:03 | ઉદાહરણ તરીકે. struct employee; |
| 01:05 | તમે કોઇપણ નામ આપી શકો છો. |
| 01:07 | હવે આપણે જોઈશું કે સ્ટ્રક્ચર વેરિયેબલ કેવી રીતે જાહેર કરવું.
|
| 01:12 | આ માટે સીન્ટેક્ષ છે,
|
| 01:14 | struct struct_name અને struct_var;
|
| 01:17 | struct_var એ struc_name ટાઇપ નો વેરિયેબલ છે.
|
| 01:22 | ઉદાહરણ તરીકે. struct employee addr; |
| 01:27 | addr એ employee ટાઇપ નો વેરિયેબલ છે. |
| 01:31 | ચાલો આપણા ઉદાહરણ પર જઈએ. |
| 01:33 | મેં એડિટરમાં પહેલેથી જ પ્રોગ્રામ લખ્યો છે |
| 01:36 | તો ચાલો હું તે ખોલું. |
| 01:38 | Note that our filename is structure.c |
| 01:42 | In this program we will calculate the total marks of three subjects using structure |
| 01:49 | Let me explain the code now. |
| 01:51 | This is our header file. |
| 01:53 | Here we have declared a structure as student.
|
| 01:57 | Then we have declared three integer variables as english, maths and science.
|
| 02:04 | Variables defined under the structure are called as members of the structure. |
| 02:10 | This is our main function |
| 02:12 | Here we have declared an integer variable total. |
| 02:17 | Now we have declared a structure variable stud. stud is the variable of type student,it is used to access and modify the structure members
|
| 02:30 | Here we have modified the members |
| 02:32 | By assigning them values as 75, 70 and 65. |
| 02:38 | Here we calculate the total of three subjects. |
| 02:42 | Then we print the result. |
| 02:44 | This is our return statement. |
| 02:47 | Now click on Save |
| 02:49 | Let us execute the program |
| 02:51 | Please open the terminal window by pressing |
| 02:54 | Ctrl, Alt and T keys simultaneously on your keyboard. |
| 03:00 | To compile |
| 03:01 | Type; gcc space structure.c space -o space struct |
| 03:10 | And press Enter |
| 03:12 | To execute |
| 03:13 | Type./struct Press Enter |
| 03:18 | The output is displayed as: Total is 210 |
| 03:22 | Now we will execute the same program in C++ |
| 03:26 | Come back to our program. |
| 03:28 | I will edit the same code |
| 03:31 | First press shift, cntrl and S keys simultaneously on the keyboard |
| 03:37 | Now save the file with an extension .cpp and click on save |
| 03:44 | Let us change the header file as iostream |
| 03:48 | Now include the using statement and click on save |
| 03:57 | Structure declaration in C++ is same as in C |
| 04:02 | So no need to change anything here |
| 04:05 | At the end we will replace the printf statement with the cout statement. |
| 04:08 | Delete the format specifier and \n |
| 04:16 | Now delete the comma |
| 04:17 | Type two opening angle brackets. |
| 04:21 | Here delete the closing bracket |
| 04:23 | and type two opening angle backets |
| 04:25 | And within the double quotes type \n |
| 04:29 | Now click on Save |
| 04:31 | Let us execute the program |
| 04:33 | Come back to our terminal |
| 04:35 | To compile type g++ space structure.cpp space -o space struct1 |
| 04:47 | Here we have struct1 because we dont want to overwrite the output parameters for the file structure.c |
| 04:55 | Now press Enter |
| 04:57 | To execute type ./struct1 |
| 05:02 | Press Enter |
| 05:04 | The output is displayed as: Total is 210 |
| 05:08 | You can see that the output is same as our C code |
| 05:12 | Now let us go back to our slides. |
| 05:15 | We will summarize now. In this tutorial we learned, |
| 05:18 | Structure. |
| 05:19 | Syntax of a structure. |
| 05:21 | eg. struct struct_name; |
| 05:24 | To access members of a structure. |
| 05:26 | Eg: stud.maths = 75; |
| 05:30 | To add the structure variables. |
| 05:33 | Eg: total = stud.eng + stud.maths + stud.science; |
| 05:40 | As an assignment, |
| 05:41 | Write a program to diplay the records of an employee. |
| 05:45 | Like name, address, designation, salary. |
