Basically,
&array[i];
That is, the memory location for an array object with index i.
Or, you can do:
(array + i);
This is known as searching.
swag variable
(array.length - 1) will find the index of the last element in an array (or -1 if the array is empty).
1010
To begin, obtain the element to be added, such as x Then, say pos, get the position where this element will be put. Then shift the array items one position ahead, then do the same for all the other elements next to pos. Because the location pos is now empty, insert the element x there.

Your best bet would probably be to iterate through the array using a for loop and compare each value to the current low and high values (which you would store in a local variable) for example: for each element in array { if current is less than lowest_value lowest_value = current else if current is greater than highest_value highest_value = current }
by using index position we can find the particular element in array.

To implement array data structure, memory bytes must be reserved and the accessing functions must be coded. In case of linear arrays, the declaration statements tell how many cells are needed to store the array. The following characteristics of the array are used to calculate the number of cells needed and to find the location or address of any element of the array.1. The upper bound (UB) of the index range.2. The lower bound (LB) of the index range. In C/C++, LB is zero.3. The location in memory of the first byte in the array, called base address of the array (Base)4. The number of memory bytes needed for each cell containing one data element in the array (size, denoted by W)By cell we mean a unit of memory bytes that will be assigned to hold a value of respective data element.During the compilation of the program, the information about characteristics of the array is stored in a table called DOPE VECTOR. When compiler comes across references to an array element, it uses this information that will calculate the element's location in memory at runtime.

You cannot delete from an array.
int findMax(int *array) { int max = array[0]; for(int i = 1; i < array.length(); i++) { if(array[i] > max) max = array[i] } return max; }
which element of the array does this expression reference num[5]
Computer memory is linear so a one dimensional array can be mapped on to the memory cells in rather straight forward manner.To find the actual address of an element one needs to subtract one from the position of the desired entry and then add the result to the address of the the first cell in the sequence.Having said that therefore it is necessary to know the starting address of the space allocated to the array and the size of the each element, which is same for all the elements of an array.The the location of the Ith element would be B+I*S where B is the base address(Starting address of the array) and S is the size of each element of the array.
C-style example: sometype array [P][Q][R]; addr (array,I,J,K) = (char *)array + sizeof (sometype)*(I*Q*R + J*R + K)
