Does an array have an address?

Each element of an array has own address. Address of an array is the address of it’s first element. In C++, an object is some bytes in memory. We call the location of the first of those bytes it’s address.

What is the base address of an array?

Base address of an array is the address value of the starting point of the array.It is usually the address of the first element of the array. Explanation: Base address can be used to calculate the other values of the array if width of array and all info is given.

Why array name is not a variable?

When an array is used as a value, its name represents the address of the first element. When an array is not used as a value its name represents the whole array.

Can you have variables in an array?

An array is a variable containing multiple values. Any variable may be used as an array. There is no maximum limit to the size of an array, nor any requirement that member variables be indexed or assigned contiguously. Arrays are zero-based: the first element is indexed with the number 0.

What is the difference between array and &array?

Basically, “array” is a “pointer to the first element of array” but “&array” is a “pointer to whole array of 5 int”. We hope that we could clarify that any array name itself is a pointer to the first element but & (i.e. address-of) for the array name is a pointer to the whole array itself.

How do I find the address of an array element?

If array is declared by a[m][n] where m is the number of rows while n is the number of columns, then address of an element a[i][j] of the array stored in row major order is calculated as, Address(a[i][j]) = ((j*m)+i)*Size + BA.

How is array Addressing done?

Array Addressing a(i) refers to the i number in an array a with one row. For example, if >2 a = [2, 4, 6, ,100] then a(1)=2, a(2)=4., a(49)=98, a(50)=100. then a(1,2) = 3 and a(2,1) = 2. We will focus here on arrays with only one row.

How does an array differ from an ordinary variable?

An ordinary variable can hold only one value whereas an array variable can refer to a group of values of the same data type by using a subscript.

What is the difference between a variable and an array?

A variable is a single box able to store a single item of a single type. An array is a large box holding multiple smaller boxes holding the same type of items. The advantage of using an array is using the same name to refer to different items of different values.
