Good evening, everyone. I'm a beginner in programming and I have two questions:
When a double-array in C # exists, each array position starts as null or zero?
Is there a method that returns the last OCCUPIED position of an array? For example, I have an array of n positions and I want to insert one more element into this array in an ordered sequence, except that such a position is unknown, ie I need to know somehow the subsequent position that is empty.
li>When an array of type double in C # is reached, each position of the array starts without null or zero?
With zero. Here is a table with all default values of C # variables .
Is there a method that returns the last OCCUPIED position of an array?
Yes.
array.Length
I assume% with a array of any type.
For example, I have an array of n positions and I want to insert another element in this array in an ordered sequence, except that such a position is unknown, that is, I need to know in some way the subsequent position that is empty. >
To insert an element at the end of array , do so:
Array.Resize(ref array, array.Length + 1);
array[array.Length - 1] = valordouble;
arrays are not good dynamic structures. It would be best to use array .
