Is it necessary to read or display the elements of an array in order of its subscripts?
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.

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.
What would the valid subscript values be in a four element array of doubles?
since the array is four elements and array subscripts start at zero, the valid ones would be 0, 1, 2, 3
How do you use subscripts with an array?
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.
Can array subscript be -1?
No, array subscripts cannot be -1 in most programming languages. Array indices typically start at 0, meaning valid subscripts are non-negative integers. Using a negative index like -1 would usually result in an error or undefined behavior, depending on the language being used. Some languages, like Python, allow negative indexing to access elements from the end of the array, but this is not the case for all languages.
Why should indexes be used instead of subscripts to identify array elements?
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.

What does it mean for a subscript to be out-of -bounds?
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.

Accept 5 numbers in an array and display it?

Do any languages have array subscripts beginning with 1?
Yes, PHP and C both do.
How do you print array variable without using array subscripts?
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.
What is array literal in as2?
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.
What is the difference between subscript and subscripted variable in c plus plus?
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]).
How do you declare a string array and add elements to it in C plus plus?
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.
