It means the array has a sentinel to mark the end of the array. Any elements that follow the sentinel element are deemed invalid. Sentinels are usually denoted with a special value that is not used by any of the elements that precede it. Null-terminated strings are an example, where the NULL character (ASCII code 0) marks the end of a character array.

What are the differences between broadside array and end fire array?

end fire array A combination of identical and equally spaced antenna that radiate along the axis of the axis of the antenna array is known as an end fire array. the elements are fed with a current of equal magnitude but opposite in phase.due to this variation in phase ,the radiation obtained is unidirectional. broadside array when the maximum radiation of an array is directed normal to the axis of array it is known as broadside array. in a broadside array combination a number of identical antennas are set up along a line drawn perpendicular to their respective axis.


Why numeric arrays do not end with a '0' in C programming language?

The value zero is a perfectly valid numeric array element in its own right. If we used the value zero to mark the end of a numeric array in the same way we use a null-terminator to mark the end of a string (a character array), we'd have no way of representing the value zero within the array itself. Thus when working with numeric arrays, we must keep track of the array length independently of the array.


Is end fire array antenna non resonant antenna?

yes


Can you perform insertion and deletion in an array?

You can, but it's not as straightforward as inserting or deleting from a list. This is simply because arrays are not intended for insertions or deletions other than at the end of the array. This is because an insertion requires that the entire array be reallocated (which may require the array to be copied in its entirety) simply in order to make room for the new element, which can then simply be inserted in the unused element at the end of the new array. To insert elsewhere in the array, all the elements following the insertion point need to be copied (for a second time) into the next element, starting with the last used element. the entire process can prove quite costly, especially if the elements are complex objects which would require their copy constructors to be invoked at least once and possibly twice. This is why it is generally better to use arrays of pointers to objects rather than arrays of objects, as copying a pointer is more efficient than copying an object. However, if your array undergoes frequent resizing in order to accommodate insertions and deletions, then you really would be better off using a list.


How you work character type data in array c plus plus?

It's not clear from the question what you mean by "work". However character data types (char and wchar_t) are intended to store character codes and they work exactly the same whether as a single variable or as an array of characters. If you want to use the array as a string, however, remember to include a null-terminator at the end of the string.

Php array to xml file?

If you mean taking an array and making an xml file out of it then you would need to dump the array information into the xml file. $fp = fopen(filename, "a"); $str = <author>$array['author']</author> fwrite($fp,$str); fclose($fp); that way it will add the contents to the end of thhe file


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

Is an array that is in sorted order a min heap?

Yes, an array that is in sorted order is considered a min-heap because the smallest item in the array is the root. Also, the rest of the items in the array will gradually get bigger from the root until the end of the array.
