WebThe srand () function in C++ seeds the pseudo-random number generator used by the rand () function. It is defined in the cstdlib header file. Example #include #include using namespace std; int main() { // set seed to 10 srand ( 10 ); // generate random number int random = rand (); cout << random; return 0; } // Output: 71 WebC Standard General Utilities Library. This header defines several general purpose functions, including dynamic memory management, random number generation, communication with the environment, integer arithmetics, searching, sorting and converting.
