- 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.

∙ 13y agoAn array is an indexed list of multiple variables of the same type. An array can be of any type and length.
For example, int a[4]; creates an array of 4 integer elements namely a[0], a[1], a[2] and a[3]. Here a is the name of the array and the subscript (numbers written in []) is called index.

∙ 13y agoAn array is a data structure consisting of one or more (1..N) similar elements, each with a tuple index, which is usually a numerical subscript. The memory address of each element is computed algorithmically by the language compiler or interpreter from the tuple index.

How array differ from ordinary variable?
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].....
Passing an array name to a pointer assigns the first memory location of the array to the pointer variable?
Yes, passing an array name to a pointer assigns the first memory location of the array to the pointer variable. An array name is the same as a pointer to the first location of the array, with the exception that an array name is a r-value, while a pointer is an l-value.
If structure is arraythen an individual array element can be accessed by writing a variable?
A structure is not an array. Individual array elements are accessed through a number, called a "subscript". This subscript can be a constant, or a variable, or any expression that can be evaluated to give an integer.A structure is not an array.

How do you swap two adjecent no in array in c?
Option 1) Use a temporary variable: int x = array[i]; array[i] = array[i+1]; array[i+1] = x; Option 2) Use bit operators: array[i] ^= array[i+1] ^= array[i];
What is the difference between an array shift and unsetting a variable in PHP?
By shifting the values in an array, you are moving a key's value to the previous key. The very first key's value is obliterated. By shifting all values in the array, all keys will have a value of NULL. Unsetting a variable is entirely different -- performing a variable unsetting causes the variable to have a value of NULL, as if it was never set.

Is there a way to use a variable to declare the size of an array in true basic?
! variable to declase the size of an array in True Basic ! set up a dummy value for array - any initial value > 0 is fine. DIM array$(999) ! ask the user for the length of the array INPUT PROMPT "Enter array size " :size ! resize the array with user defined length MAT REDIM array$(size) ! program end END

How do you convert char array into unsigned char array in c?
You can't convert the data type of any variable.
What are the limitations of a variable over advantage of array?
variable cant occupy contigious memory it may take complexity in storing vast data.this becomes easy on using the array concept....
What is array What is difference between array and simple variable?
An array stores several values - for example, several numbers - using a single variable name. The programmer can access the individual values with a subscript, for example, myArray[0], myArray[5]. The subscript can also be a variable, for example, myArray[i], making it easy to write a loop that processes all the elements of an array, or some of them, one after another.
What is syntax in c plus plus for declaring a variable?
type variable {[optional array size]} {= optional initializer};
Can an array store more then one type of variable?
No. Only a union can do that.
