srand()Prototype: void srand(unsigned int seed);Header File: stdlib.h (C) or cstdlib (C++) Explanation: Srand will seed the random number generator to prevent random numbers from being the same every time the program is executed and to allow more pseudorandomness. Example:
//Program uses time function to seed random number generator
//and then generates random number
#include <cstdlib>
#include <ctime>
#include <iostream>
using namespace std;
int main()
{
srand((unsigned)time(NULL));
int d=rand()%12;
cout<<d;
}
