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 < stdio.h >
#include < math.h >
#include < stdlib.h >
#include < time.h >


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();

}

I am building a website for my own in google pages. Not a website still. My friend said i shouldn't not use something made by google for my own web page. What ever i'm continuing. u can take a look here.

Here is a code which will guide u through this.

The bad thing is the file is not still posted :D

I am posting again. Nothing important is happening down here. I have bought a phone Motorola W220. It cost me 5550/= tk only. It's a good looking phone but it has no java support but it can access wap sites.
