**Random Integer 0 or 1 C++ Forum**

Range: rand returns numbers in the range of [0, RAND_MAX), and RAND_MAX is specified with a minimum value of 32,767. Portable code cannot assume that the range is any larger than this, so portable code is very limited in the random numbers that can be predictably generated. Compare this with better random number generators that have a range of 32 or 64 bits. Period: The period of rand is... C Library -

5/11/2015 · The bug is worse than that (I am missing a -1) but the problem is more that rand() does not produce RAND_MAX very often at all and the "target range" is so small.... I don't know how to set RAND_MAX. In the rand() function, it is used to show the maximum of the random number generated. The rand() function generates a number between 0 and RAND_MAX. I'm kind of new to C and I don't know how to set it. Thanks for your help

19/10/2006 · result = (rand() % 6) + 1; This is not a good way to get a random value between 1 and 6 because the normal algorithm implemented by rand() does not give very good randomness in the low order bits of the value produced. how to set a colour display on map 3d screen This will return you a number between 0 and RAND_MAX (also defined in stdlib.h), which is guaranteed to be at least 32767. If you want to get different random numbers each time you run your program, you will also need to use the srand() function as well, as this will seed the generator.

## How To Set Rand_max In C

Expands to an integer constant expression equal to the maximum value returned by the function std::rand. This value is implementation dependent. It's guaranteed that this value is at least This value is implementation dependent.

- 8/12/2006 · cannot set RAND_MAX to some other value, and there is no way of requesting that rand() return numbers in some other range.) If you're starting with a random number generator which returns
- rand() in C returns int, which is not a floating point type. The docs for rand() indicate that it returns an integer between 0 and RAND_MAX , inclusive. – cdhowie Nov 24 '10 at 19:03 2
- cout << "RAND_MAX=" << RAND_MAX << endl; // RAND_MAX=32767 We can set the range of generated numbers using % (modulus) operator by specifying a maximum value. For instance, to generate a whole number within the range of 1 to 100:
- If the seed is set to 1 then the generator is reinitialized to its initial value. Then it will produce the results as before any call to rand and srand. Then it will produce the results as before any call to rand and srand.
