Formats that use delimiter-separated values (also DSV) [2]: 113 store two-dimensional arrays of data by separating the values in each row with specific delimiter characters. Most database and spreadsheet programs are able to read or save data in a delimited format.
Each cell of this list is called a cons (in Scheme, a pair) and is composed of two pointers, called the car and cdr. These are respectively equivalent to the data and next fields discussed in the article linked list. Of the many data structures that can be built out of cons cells, one of the most basic is called a proper list.
A pipe is an inter-process communication mechanism originating in Unix, which directs the output (standard out and, optionally, standard error) of one process to the input (standard in) of another. In this way, a series of commands can be "piped" together, giving users the ability to quickly perform complex multi-stage processing from the ...
Pivot tables are not created automatically. For example, in Microsoft Excel one must first select the entire data in the original table and then go to the Insert tab and select "Pivot Table" (or "Pivot Chart"). The user then has the option of either inserting the pivot table into an existing sheet or creating a new sheet to house the pivot table.
In any case, even when a variable is implicitly initialized to a default value like 0, this is typically not the correct value. Initialized does not mean correct if the value is a default one. (However, default initialization to 0 is a right practice for pointers and arrays of pointers, since it makes them invalid before they are actually ...
Because Excel is widely used, it has been attacked by hackers. While Excel is not directly exposed to the Internet, if an attacker can get a victim to open a file in Excel, and there is an appropriate security bug in Excel, then the attacker can gain control of the victim's computer. [125] UK's GCHQ has a tool named TORNADO ALLEY with this purpose.
Some languages, such as Pascal, Fortran, Ada and many dialects of BASIC, use a different name for a callable unit that returns a value (function or subprogram) vs. one that does not (subroutine or procedure). Other languages, such as C, C++, C# and Lisp, use only one name for a callable unit, function.
We assume that is well behaved and that we can reverse the order of integration. Also, recall that flow is normal to the unit area of the cell. Now, since in one dimension , we can apply the divergence theorem, i.e. =, and substitute for the volume integral of the divergence with the values of () evaluated at the cell surface (edges / and + /) of the finite volume as follows:
