What is the base address of an array?


Chester Watt   |   Member since 2013  |  10+ Answers Submitted  |  ✔ Verified

Base address means the location of the first element of the array in the memory. Memory address of any element implies the particular location in the memory where the element is stored.

In this manner, how do you find the base address of an array?

Address Calculation in Double (Two) Dimensional Array:

  1. B = Base address.
  2. I = Row subscript of element whose address is to be found.
  3. J = Column subscript of element whose address is to be found.
  4. W = Storage Size of one element stored in the array (in byte)
Likewise, what is base address and offset address? In computing, a base address is an address serving as a reference point (" base ") for other addresses. Related addresses can be accessed using an addressing scheme. Under the relative addressing scheme, to obtain an absolute address, the relevant base address is taken and offset (aka displacement) is added to it.

Similarly, what is the address of an array?

The address of an array is the address of the first element of the array. In the above array, the first element is allocated 4 bytes. The number of the first byte is the address of the element. Similarly, the second element is also residing on the next 4 bytes.

Does mentioning the array name gives the base address in all the contexts?

Syntactically, the compiler treats the array name as a pointer to the first element. You can reference elements using array syntax, a[n], or using pointer syntax, *(a+n), and you can even mix the usages within an expression.

Can we change the base address of an array?

a) In one line : " We can't change the base address of an array because it is the constant with the help of which the compiler refers to all the elements held by the array . " That's why base Address is fixed in case of array . An N element array holds a contiguous space in memory for N elements.

What does Column major mean?

In computing, row-major order and column-major order are methods for storing multidimensional arrays in linear storage such as random access memory. The difference between the orders lies in which elements of an array are contiguous in memory.

What is the difference between arr and &arr?

The two have the same value but different types. When it's used by itself (not the operand of & or sizeof ), arr evaluates to a pointer to int holding the address of the first int in the array. &arr evaluates to a pointer to array of three int s, holding the address of the array.

What is address in data structure?

(1) A location of data, usually in main memory or on a disk. You can think of computer memory as an array of storage boxes, each of which is one byte in length. Each box has an address (a unique number) assigned to it. By specifying a memory address, programmers can access a particular byte of data.

Why can't we increment an array like a pointer?

It's because array is treated as a constant pointer in the function it is declared. There is a reason for it. So, if we will have the liberty to to change(increment or decrement ) the array pointer, it won't point to the first memory location of the block. Thus it will loose it's purpose.

What is a two dimensional array?

Two-dimensional Arrays. A 2D array has a type such as int[][] or String[][], with two pairs of square brackets. The elements of a 2D array are arranged in rows and columns, and the new operator for 2D arrays specifies both the number of rows and the number of columns.

What is sparse matrix in data structure?

A matrix is a two-dimensional data object made of m rows and n columns, therefore having total m x n values. If most of the elements of the matrix have 0 value, then it is called a sparse matrix. Storage: There are lesser non-zero elements than zeros and thus lesser memory can be used to store only those elements.

What is data structure in C?

Data Structures in C are used to store data in an organised and efficient manner. The C Programming language has many data structures like an array, stack, queue, linked list, tree, etc. A programmer selects an appropriate data structure and uses it according to their convenience.

How do you find the memory address?

To put it another way, Step 1: calculate the length of the address in bits (n bits) Step 2: calculate the number of memory locations 2^n(bits) Step 3: take the number of memory locations and multiply it by the Byte size of the memory cells.

Is array a pointer?

An array is an array and a pointer is a pointer, but in most cases array names are converted to pointers. Here is a pointer: int *p; p doesn't contain any spaces for integers, but it can point to a space for an integer.

What is row major array?

Row Major Order is a method of representing multi dimension array in sequential memory. In this method elements of an array are arranged sequentially row by row. Thus elements of first row occupies first set of memory locations reserved for the array, elements of second row occupies the next set of memory and so on.

What is address calculation?

Address should be calculated using one of the two methods as the following, a. Row-by-Row. Location (A [j, k]) = Base (A) + w [N (j-1) + (k -1)] Here, j and k indicates index value of the element whose address you want to search.
