Array of C Programming

1. One-dimensional array
   Example a is a integer variabel
   

   int a; main() { a = 27; printf("%d", a); getch(); }

   
   If we want to be the a variabel as an array variabel sized 3:

   int a[3]; main() { a[1] = 27; a[2] = 29; a[3] = 32; printf("%d", a[1]); printf("\n%d", a[2]); printf("\n%d", a[3]); getch(); }

   
   So there are 3 values of a in the example of this one-dimensional array, are: 1st-a, 2nd-a, and 3rd-a. On this one-dimensional array, all that valus is defined as a ROW:
   

   1st-a

   2nd-a

   3rd-a

   or

   27

   29

   32

   
   In that 1 ROW there are 3 values, because there are 3 COLUMNs. So value in the example of this one-dimensional array can be defined as:

   a on 1st-row 1st-column

   a on 1st-row 2nd-column

   a on 1st-row 3rd-column

2. Two-dimensional arrays
   In the example of one-dimensional array above:

   27

   29

   32

   
   added one row:

   27	29	32
   2	3	5

   
   So that now there are 2 ROWs 3 COLUMNs

   int a[2][3]; main() { a[1][1] = 27; a[1][2] = 29; a[1][3] = 32; a[2][1] = 2; a[2][2] = 3; a[2][3] = 5; printf("%d", a[1][1]); printf("\n%d", a[1][2]); printf("\n%d", a[1][3]); printf("\n%d", a[2][1]); printf("\n%d", a[2][2]); printf("\n%d", a[2][3]); getch(); }
