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.
What else can I help you with?
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.
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.
Do any languages have array subscripts beginning with 1?
Yes, PHP and C both do.
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

Array subscripts are always a large numbers b characters c negative values d integers?
d integers
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.
What is starting subscripts value for integers arrays?
0. For many (every) languages, for every type of array, the starting subscript is zero.
When to use subscripts when writing a formula?
Do you mean subscripts like H2O (ie the 2 would be subscripted)?
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.
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];
How can you use the word subscript in a sentence?
subscripts can't be changed.
