The individual elements of the array can be referenced by using subscript. Array subscripts are treated as signed 32 bit integer. In arrays, first element occupies the position zero, the second element occupies the position one and so on followed by the last element subscripted by [N-1] where N is the number of elements in the array. Example: For (i=0;i<10;i++) arr[i]=0; It clears the ten elements of the array “arr" to zero. If an array has two dimensions then the two subscripts has to be specified while referencing. First subscript refers to the row and the second subscript refers to the column. Example: For (i=0;i<10;i++) For(j=0;j<10;j++) arr[i][j]=0; Similarly if an array has three dimensions then the first subscript may refer to X co-ordinate , second subscript may refer to the Y co-ordinate and the third subscript may refer to the Z co-ordinate. Example: arr[2][4][8]=10; It sets the value of the array at a point (2,4,8) as 10. And so on.
To write the formula of a binary molecular compound, first use the prefixes in the name to tell you the subscript of each element in the formula. Then, write the correct symbols for the two elements with the appropriate subscripts.
