which statement, executed once at the start of the program, enables a program to generate pseudo-random numbers with variable newseed as the seed?
Srand(time(0)) executed once at the start of the program, enables a program to generate pseudo-random numbers with variable newseed as the seed.
We evaluate each choice separately to do this.
(a) srand()
The use of srand() in the example above is improper because it needs an argument to be used (2)
(b) srand(time(0))
Because time(0) allows srand() to seed to the current time, the sentence above is acceptable and will always produce unique pseudo random numbers.
(c) Srand (100)
The aforementioned is a legitimate use of srand(), however because srand() has a seed size of only 100, rand() will produce the same set random integers.
(d) time(srand())
Additionally, the aforementioned use of srand is improper ().

A file path is a complete address that describes the exact location of a file. true false
It is true that a complete address that specifies a file's precise location is known as a file path. That question is related to file system.
A file system stores and arranges files on some type of storage device—typically one or more hard drives—in a way that makes it simple to access and retrieve them. The majority of current file systems store the files in a tree-like (or hierarchical) form.
One or more root nodes can be found at the top of the tree. There are directories and files beneath the root node (folders in Microsoft Windows). Each directory has the ability to hold files and subdirectories, which in turn have the ability to hold files and subdirectories, and so on, potentially indefinitely.
The sample directory tree with a single root node is depicted in the accompanying diagram. Multiple root nodes are supported by Microsoft Windows. Each root node corresponds to a volume, like C: or D: The root node that the Solaris OS supports is identified by the slash (/).
