By no means; you can access any random array element. If you have ever seen examples which process them in order, it is because of the following: when the order doesn't matter (for example, you want to calculate the sum of all the array elements), it is easiest to process them in order.
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.
since the array is four elements and array subscripts start at zero, the valid ones would be 0, 1, 2, 3
An array is a list of several related elements. You use the subscript to specify which element you want to access. For example, in Java you might have an array called myArray, with 10 elements (numbered from 0 to 9); myArray[3] would access the fourth element in the array. A variable may be used instead of a constant.
You cannot uses indices instead of subscripts. The subscript operator [] requires an index in order to determine the subscript. Even if you don't use the subscript operator you still need an index to determine the offset of the subscript. Indeed, the only time you do not need an index is when traversing the array using a roving pointer, which is arguably more efficient than using a subscript to traverse an array since subscripts use multiplication instead of the much simpler increment/decrement operation.
Accept 5 numbers in an array and display it.

This is a type of error that usually occurs in computer programs. An array is defined in which the elements of the array are identified by one or more subscripts. Suppose you have an array which is declared to be of dimension 23. Then if the program tries to access element 26 in that array, it cannot because there is no element of the array in that position. That is when you will get this error message.

Yes, PHP and C both do.
Well the most prolific answer to this query would be the use of pointers.Use a pointer and allocate it to the array of interest and start printing.
An array literal is a comma-separated list of the elements of an array. An array literal can be used for initializing the elements of an array.
You cannot add elements to a fixed array in C or C++. If, however, the array is declared as a pointer to an array, you can add elements by allocating a new array, copying/adding elements as needed, reassigning the new array to the pointer, and deallocating the original array.
Subscripts are used to identify the elements in an array, where the first element has subscript 0. Thus an array of n elements has subscripts in the range 0 to n-1. Each element may itself be an array, thus allowing multi-dimensional arrays. The subscript may be a constant or a variable. However, when declaring a static array, the subscript must be a constant. Constants include literal constants as well as named constants. A subscripted variable is simply an array or a datatype that can be divided into an array. For instance, a 32-bit int can be treated just as if it were an array of two 16-bit shorts or four 1-byte chars. Thus in the 32-bit int array, int i[10], i is a subscripted variable where i[0] is the first integer and i[9] is the last. If we then say char*c=&i, c would allow us to treat i as if it were a subscripted variable with 40 char elements (c[0] to c[39]).
An ordered array is simply an array where all elements are in sorted order: int a[] = {3, 6, 9, 10, 15, 21}; // ordered array An array can either be initialised with ordered elements or the elements may be sorted after initialisation. When inserting new elements into an ordered array, the order must be maintained.
