### Random Integer 0 or 1

Hi,

For God's sake, can someone please, CLEARLY, tell me how to generate a random INTEGER between 0 and 1 (i.e. 0 or 1). I have searched all over the net, and no one has put a good working code. I hate C++ and anyone who proposed/coded the "rand()" function/class/library. If anyone tell me to do this in Java, I'll do it in a blink of an eye, but this stupid C++ drove me crazy for the past week. If I made SO MANY combination of code, that if I put that much work on anything else, I may have invented or discover something new. So, please, someone, give me a correct piece of code that has TRULY been tested.

Here are everything I grabbed from the net and what I made.

srand(time(0)); //I tried NULL as well

int a = (float)rand() / RAND_MAX; OR

int a = (float)rand() / (RAND_MAX + 1); OR

int a = (double)rand() / (double)(RAND_MAX) OR

int r = (rand() % 1) OR

======

double a = (double)rand() / RAND_MAX;

int b = a;

I tried lots of other casting, but everything gives me only ZERO.

You're a rather obvious troll, but what the hell:
`int a=rand()%2;`
A quick Google search for "c++ random number generation" returned this http://www.learncpp.com/cpp-tutorial/59-random-number-generation/. Shouldn't be any trouble for a talented Java programmer like yourself. Isn't Google great?

Rather than searching for recipes, you should think about the problem yourself for a minute. It's not hard. If you know anything about math, you know that taking the remainder of x/2 where x is an integer you get either 0 or 1 depending upon whether x is odd or even. All you need to do is find a source of random integers. rand() is just that.
 I hate C++

lol. Angry man is angry =]
Hey, before I learned C++ all random functions I had ever worked with returned a floating point value in [0,1)
` floor( 2 * random() ); //example `

So really it's just understanding that rand() returns something similar to Java's
`new java.util.Random().nextInt();`

Also, @ChangBroot: `assert __ % 1 == 0;`

roflmao - this post is hilarious in too many ways! My sides are hurting...
LMFAO!
 ``1234567891011`` ``````#include // So we can use time() function #include // To output results to console int main() // Main function required in all C++ programs and first function to be called { srand( time(NULL) ); //Randomize seed initialization int randNum = rand() % 2; // Generate a random number between 0 and 1 std::cout << randNum; // Output the results to console return 0; //Generate an "EXIT SUCCESS" return code }``````

Clear enough for you? I find it hard to believe that you're so good at java but couldn't figure out something as simple as this, no offense.
