Is rand () a built in function in C?

As we know, the random function is used to find the random number between any two defined numbers. In the C programming language, the random function has two inbuilt functions: rand() and srand() function.

What is the difference between rand () and Srand () in C++?

The rand() function in C++ is used to generate random numbers; it will generate the same number every time we run the program. In order to seed the rand() function, srand(unsigned int seed) is used. The srand() function sets the initial point for generating the pseudo-random numbers.

What is the range of rand () in C?

The C library function int rand(void) returns a pseudo-random number in the range of 0 to RAND_MAX. RAND_MAX is a constant whose default value may vary between implementations but it is granted to be at least 32767.

Why is rand () giving me the same number?

The RAND function in stand-alone applications generates the same numbers each time you run your application because the uniform random number generator that RAND uses is initialized to same state when the application is loaded.
