• void srand (unsigned int seed) ... The function accesses and modifies internal state objects, which may cause data races with concurrent calls to rand or srand.
  • The srand() function in C++ seeds the pseudo-random number generator used by the rand() function. It is defined in the cstdlib header file.
  • void srand( unsigned int seed ); Parameters. ... Calling rand before any call to srand generates the same sequence as calling srand with seed passed as 1.
  • srand() function is an inbuilt function in C++ STL, which is defined in <cstdlib> header file. srand() is used to initialize random number generators.
  • If rand() is used before any calls to srand(), rand() behaves as if it was seeded with srand(1). ... srand() is not guaranteed to be thread-safe.
  • C srand() function (stdlib.h): The srand() function is used to set the starting point for producing a series of pseudo-random integers.
  • In C programming, srand() is a function provided by the standard library that is used to seed the random number generator. ... c srand((unsigned)time(NULL))
  • In the C Programming Language, the srand function initializes the sequence of pseudo-random numbers generated when the rand function is called.
  • srand is defined in header stdlib.h. In short, the srand does seed simple pseudo-random number generator. srand is defined as follows
  • If rand() is called before any calls to srand() are made, the same sequence shall be generated as when srand() is first called with a seed value of 1.
