00.01 | Arrays in C and C++. પરનાં સ્પોકન ટ્યુટોરીયલમાં સ્વાગત છે. |
00.07 | આ ટ્યુટોરીયલમાં આપણે શીખીશું, , |
00.09 | array.શું છે. |
00.11 | array. નું ડીકલેરેશન શું છે. |
00.13 | Initialization of an array. નું ઇનીશલાઈઝેશન |
00.16 | પર કેટલાક ઉદાહરણો |
00.18 | આપણે અમુક સામાન્ય એરરો અને તેમનાં ઉપાયો પણ જોઈશું. |
00.22 | આ ટ્યુટોરીયલને રેકોર્ડ કરવા માટે, હું વાપરી રહ્યી છું |
00.25 | ઉબુન્ટુ ઓપરેટીંગ સીસ્ટમ આવૃત્તિ 11.04. |
00.30 | gcc અને g++ કમ્પાઈલર આવૃત્તિ 4.6.1.
|
00.36 | ચાલો Arrayના પરીચય સાથે શરૂઆત કરીએ. |
00.39 | Array એ ડેટા અથવા કે સમાન ડેટા-પ્રકાર એલીમેન્ટ્સનું એક કલેક્શન છે. |
00.44 | Array ઇન્ડેક્ક્ષ 0 થી શરુ થાય છે. |
00.48 | પ્રથમ એલિમેન્ટ ઇન્ડેક્ક્ષ 0 પર સંગ્રહિત થાય છે. |
00.52 | arraysત્રણ પ્રકારના છે. |
00.55 | Single dimensional array. |
00.57 | Two dimensional array અને |
00.59 | Multi-dimensional array. |
01.01 | આ ટ્યુટોરીયલમાં આપણે 'single dimensional array ની ચર્ચા કરીશું. |
01.06 | ચાલો જોઈએ 'single dimensional array ને કેવી રીતે ડીકલેર કરવું. |
01.09 | આ માટેનું સિન્ટેક્સ છે. |
01.11 | data-type name of the array and size |
01.16 | ઉદાહરણ,અહી આપણે એક ઈંટીજર અરે સ્ટારને ડીકલેર કર્યું છે જે 5 એલિમેન્ટ ધરાવે છે. |
01.24 | Array ઇન્ડેક્ક્ષ star 0 થી star 4સુધી શુરુઆત થશે. |
01.29 | આપણે અરેનું ડીકલેરેશન જોયું
|
01.32 | હવે આપણે અરેનું ઇનીશલાઈઝ જોશું. |
01.35 | આ માટેનું સિન્ટેક્સ છે. |
01.38 | data-type,( name of the array ), size is equal to elements
|
01.44 | ઉદાહરણ,અહી આપણે એ ઈંટીજર અરે સ્ટાર માપ 3 સહીત ડીકલેર કર્યો છે.અરે ના એલિમેન્ટ 1 , 2 અને 3 છે |
01.54 | 'અહી ઇન્ડેક્ક્ષ star 0 થી શરુ થઈનેstar 2સુધી છે. |
01.59 | હવે ચાલો ઉદાહરણો તરફે જઈએ |
02.01 | મેં એડીટર પર પહેલેથી જ પ્રોગ્રામ ટાઈપ કર્યો છે. |
02.04 | તો ચાલો હું તે ખોલું. |
02.06 | નોંધ લો આપણી ફાઈલ નું નામ array.c છે.
|
02.10 | In this program, we will calculate the sum of the elements stored in an array. |
02.16 | Let me explain the code now |
02.18 | This is our header file.
|
02.20 | This is our main function.
|
02.22 | Here, we have declared and initialized an array star with size 3. |
02.28 | The elements of the array are 4, 5 and 6 |
02.33 | Then we have declared an integer variable sum |
02.36 | Here we add the elements of the array and store the result in sum. |
02.41 | Note that 4 will be store at index 0, 5 will be store at index 1 and 6 will be store at index 2 |
02.50 | Then we print the sum. |
02.52 | This is our return statement. |
02.54 | Now, click on Save. |
02.57 | Let us execute the program. |
02.59 | Please open the terminal window by pressing Ctrl, Alt and T keys simultaneously on your keyboard. |
03.09 | To compile type, gcc space array dot c space hypen o array and press Enter. |
03.19 | To execute type, dot slash array .Press Enter |
03.24 | Here the output is displayed as, |
03.26 | The sum is 15. |
03.28 | Now let us see some common errors which we can come accross.
|
03.32 | Come back to our program. |
03.34 | Suppose here, at line number 4 we miss the curly brackets. |
03.39 | Click on Save. Let us see what happens |
03.42 | Come back to the terminal. |
03.44 | Let us compile as before. |
03.47 | We see an error |
03.49 | Invalid initializer and Expected identifier or bracket before numeric constant. |
03.56 | This is because arrays must be initialized within curly brackets. |
04.01 | Come back to our program. Let us fix the error. |
04.04 | Type the curly brackets here at line number 4. |
04.09 | Now, click on Save |
04.12 | Lets us execute. Come back to the terminal |
04.15 | Let us compile as before. Let us execute as before.
|
04.19 | Yes,it is working
|
04.21 | Now we will execute the same program in C++. |
04.25 | Come back to our program. |
04.28 | I will change a few things here. |
04.30 | First press Shift , Ctrl and S keys simultaneously on your keyboard |
04.38 | Now save the file with the extension dot cpp and click on Save |
04.44 | Let us change the header file as iostream |
04.49 | Now include the using statement |
04.55 | The declaration and initialization of an array is same in C++ |
05.01 | Hence no need to change anything here |
05.04 | Now replace the printf statement with the cout statement. |
05.09 | Delete the format specifier and back slash n, now delete the comma and type two opening angle brackets |
05.17 | Delete the bracket here. Again type two opening angle brackets and within the double quotes type back slash n |
05.26 | Now click on Save. |
05.29 | Let us execute. Come back to a terminal. |
05.32 | To compile type, g++ space array dot cpp space hypen o space array1. |
05.42 | Here we have array1 because we dont want to overwrite the output parameter array for the file array dot c |
05.51 | Now press Enter. |
05.54 | To execute type, dot slash array1 .Press Enter |
05.59 | The output is displayed as, The sum is 15 |
06.02 | We can see that it is similar to our C code |
06.07 | Now, we will see another common error.
|
06.10 | Come back to our program |
06.12 | Suppose here, at line number 7 |
06.14 | I will type star[1], star[2] and star[3]; |
06.23 | Click on Save. |
06.24 | Let us execute. Come back to our terminal |
06.28 | Let me clear the prompt. |
06.30 | Let us compile as before. |
06.33 | Let us execute as before. |
06.36 | We get an unexpected output.
|
06.39 | This is because array index starts from 0. |
06.43 | Come back to our program. We can see here the array index starts from one. |
06.49 | Hence it is giving an error. Let us fix the error. |
06.54 | Type 0 here 1 and 2. Click on Save |
07.02 | Let us execute. Come back to our terminal |
07.05 | Let us compile as before. Execute as before |
07.09 | Yes, it is working. |
07.12 | Now, we will go back to our slides |
07.14 | Le us summarize |
07.16 | In this tutorial we learned,
|
07.19 | Arrays. |
07.20 | To declare Single Dimensional Arrays. |
07.23 | To initialize Single Dimensional Arrays.
|
07.26 | example int star[3]={4, 5, 6} |
07.31 | To add the element of the array, example sum is equal to star 0 plus star 1 plus star 2 |
07.40 | As an assignment, |
07.41 | Write a program to calculate the difference of the elements stored in an array.
