No, it is not allowed to exceed the allocated size of an array. However, few compilers check, so if the programmer fails to check, he or she can get in trouble, by corrupting other memory or throwing a bus exception.

What is the index number of the last element of an array with 9 elements?

(array.length - 1) will find the index of the last element in an array (or -1 if the array is empty).


How will you find the location of an element of an array?

Basically, &array[i]; That is, the memory location for an array object with index i. Or, you can do: (array + i);


What do array subscripts always have?

Array subscripts always have a zero-based index. In languages that allow an n-based index, the index is simply offset by n elements, so the compiler subtracts n from the given index to obtain the zero-based index. Arrays are always zero-based because the first element of an array is found zero elements from the start of the array.


In VB SCRIPT the first array index is always?

All languages use zero-based subscripting to index array elements because the first element is always allocated zero elements from the start address of the array. Very few languages default to a one-based subscript, however some languages, including VBScript, do allow you to change the lower-bound. Some algorithms are easier to implement with one-based subscripting, however you can also choose any lower and upper bound as appropriate.


How To find a maximum number in a 2D array?

// Pseudocode int findMax( int[][] data ) { // Return if data is empty if( data.length 0 ) { return 0; } int max = data[0][0]; // Iterate through each element in the array for( int r = 0; r < data.length; ++r ) { for( int c = 0; c < data[0].length; ++c ) { // If we find a value greater than the current max, update max if( data[r][c] > max ) { max = data[r][c]; } } } return max; }

How can you get position of number from given some number by using array in c language?

Traverse the array from index 0 until you find the number. Return the index of that number.


Why the array is starting from zero?

By design; it makes the compiler's work easier. 1-based array's addressing-function: Address (array, index) = Address (array) + (index-1)*Elemsize(array) 0-based array's addressing-function: Address (array, index) = Address (array) + index*Elemsize (array)


What type of data is acceptable for arrays index?

The details depend on the language, but the index of an array is usually an integer data type. Anything that is compatible with an integer can be used.

What is difference between key and index in php arrays?

A key is the name of a variable in an array ($array["key"]) and the index is the position it's at ($array = ["key" => 0], the index would be 0). Keys and indices are the same if the array is not associative though ($array = [true], the key holding the value true is named 0 and is at index 0).

How do you access last index of an array if the size is set during run time?

For an array of length s, the last element has index s-1.

Why the index of an array be a positive number?

Since an array cannot contain a negative number of items, the size of an array must be at least 0. So if you ever tried to retrieve the element at a negative index in an array, it would automatically be understood to be out-of-bounds.


Why array index always starts with zero?

Because that's how the language is defined. In C, C++, and many other languages, array indecies start with zero. This is by convention, and it also reflects the fact that, in C and C++, array-index syntax can also be expressed in pointer-offset syntax. The pointer locates the first element of the array, and the offset indicates how many elements to skip. If a is an array name, then the expression a[n] is completely identical to the expression *(a+n), and vice versa.
