What is the difference between array element and variable?

Answer 1

• Array is the set of an multiple values where as variable can store single value at a time.

• The difference between the definition of array and ordinary variable is the, array is always declared, initialized, and accessed using subscript whereas ordinary variable do not have any subscript.

• The syntax for ordinary variable definition is data_type v1, v2, ….;

• And the syntax for array variable is data_type v1[N1],v2[N2],…; where v1,v2 are name of variable and N1, N2 are the integer constants indicating the maximum size of array.

Answer 2

An array is a collection of variables of the same type. Variable is a single value, while array is a collection.

Answer 3

An array is a collection of variables of the same type. For example:

int x[10];

defines 10 integer variables at consecutive memory locations starting with x[0] and ending with x[9].

Answer 4

Traditional wisdom would say that an array holds multiple values, whereas an ordinary variable hold a single value.

While this is not false per se, it is only really true in certain cases: it is true when the elements of the array are treated as individual entities, and when the variable is a simple scalar variable such as an int.

However, a variable can also be a structure or a union, capable of holding multiple values, and an array can be thought as a single variable. For example, in the C Programming language, it is common to define temporary storage for an alphanumeric string through an array of characters. While some algorithms process each character individually, the data held in the array may only be meaningful as a whole. Note that you would also call 'buffer' in the following example a variable:

void example(void) {

char* buffer[MAX_SIZE];

...

}

It is not generally right to distinguish between a variable and an array. You'd be comparing apples with Pears. Arrays are primitive aggregate data structures and belong into the same category as structures and unions. These are aggregates, because they can contain more than one scalar element. Scalars, in contrast, are atomic types of the language, types such as int, char, enum xyz, etc, in the C programming language.

Variables can be contrasted to constants.

Arrays can be contrasted to scalars (e.g. int), or to other aggregates (e.g. struct) or data structures of higher order (e.g. lists).

Answer 5

Variables such as int, char, and float are simply one number/character. And array is a collection of variables, sort of like what would be called a string in another programing language.

for example char firstcharacter; (a variable) would store only one letter, while char firstarry [11]; (an array) would store up to a 10 letter word (due to the null character on the end)

Answer 6

ordanry variable store one value at a time.

arrays are used for storing more than one value at a time in a single variable name

ordanry variable doesnt have subscript.

array must have subscript

syntax for ord. variable Datatype v1,v2......

syntax for array variable Datatype v1[n1],v2[n2].....

Answer 7

An ordinary variable holds a single value; an array variable holds multiple values.
