What is a random function in C?

In the C programming language, the random function has two inbuilt functions: rand () and srand () function. Let's understand these functions in the C language. In the C programming language, the rand () function is a library function that generates the random number in the range [0, RAND_MAX].

What is srand function in C++?

srand () function is an inbuilt function in C++ STL, which is defined in header file. srand () is used to initialize random number generators. The srand () function sets the starting point for producing a series of pseudo-random integers. If srand () is not called, the rand () seed is set as if srand (1) were called at the program start.

What is the difference between Rand() and random()?

Functions rand () and random () are either defined by POSIX since at least POSIX.1-2001 (and randomize () is not standardized). On older rand () implementations, and on current implementations on different systems, the lower-order bits are much less random than the higher-order bits. When available, random () does not suffer of this issue.

What can a random class do?

You can also use the Randomclass for such tasks as generating random T:System.Boolean values, generating random floating point values with a range other than 0 to 1, generating random 64-bit integers, and randomly retrieving a unique element from an array or collection.
