Dev C++ Srand Cannot Be Used As A Function

Feb 18, 2011 Wake is correct. But just to pick a Nit about his answer: The compiler isn't confused. It's applying the rules of the language. To resolve a name like rand, the compiler starts at the current scope and works out, until it finds the name in it's symbol table. Rand is defined in the current scope as an int, so it doesn't search any further.

1. The srand function in C seeds the pseudo random number generator used by the rand function. The seed for rand function is 1 by default. It means that if no srand is called before rand, the rand function behaves as if it was seeded with srand(1).
2. Mar 29, 2018  randomize is not a function in C. It is also not a function in C or in POSIX or even in non-portable Linux or Windows system libraries. The only context of which I’m aware where a function with some name used to exist was the Turbo C compile.

Seeds the pseudo-random number generator used by rand() with the value seed.

If rand() is used before any calls to srand(), rand() behaves as if it was seeded with srand(1).

Each time rand() is seeded with the same seed, it must produce the same sequence of values.

srand() is not guaranteed to be thread-safe.

[edit]Notes

Generally speaking, the pseudo-random number generator should only be seeded once, before any calls to rand(), and the start of the program.It should not be repeatedly seeded, or reseeded every time you wish to generate a new batch of pseudo-random numbers.

Standard practice is to use the result of a call to time(0) as the seed.However, time() returns a time_t value, and time_t is not guaranteed to be an integral type.In practice, though, every major implementation defines time_t to be an integral type, and this is also what POSIX requires.
