How to Generate a Good Random Number in C++

In c++ u can generate random numbers by calling rand() function which is built in stdlib.h . But if u use this function without setting any seed then it gives the same random value whenever u run the code again. To solve this u can give a seed to generate random number. The best seed can be the time. A seed is set up by srand(somevalue) function. So use time u have to include time.h. Now u initialize the seed in main and use rand() fucntions else where. Now u will get different random value in different time.
A sample code can be

#include
#include
#include
#include

void printSomeRand()
{
for(int i=0;i<10;i++)
{
printf(“%d \n”,rand());///use rand to generate a random number
}
}

void main()
{
srand((unsigned) time(NULL)); ///give a seed, dont give seed whenever u call rand
printSomeRand();

}
