Does random_sample() exist?

[HazySmoke)345]

According to what http://cppreference.com/cppalgorithm/random_sample.html has to say, random_sample() can be found under the <algorithm> header, so I assume that the following code would work:

code:

#include <algorithm> using namespace std; int main(){         int a[] = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15};         int b[15], c;         c = min(1,2);         random_sample(a,a+15,b,b+15); return 0;}

Unfortunately, it didn't. The compiler gave me this message:

testing.cpp: In function `int main()':
testing.cpp:8: error: `random_sample' undeclared (first use this function)
testing.cpp:8: error: (Each undeclared identifier is reported only once for each function it appears in.)

I'm sure that I've installed my compiler properly because I've always beeing using it. Also, the min() function, which is also part of <algorithm>, didn't cause any error messages.

So, is the reference guide wrong? Or is the random_sample under a namespace other than std?

Potential solution.

Or just:

code:

#include <algorithm> using namespace std; int main() {    int a[] = { 1,  2,  3,  4,  5,                6,  7,  8,  9, 10,               11, 12, 13, 14, 15};    int b[15]    int c = min(1, 2);    copy(a, a + 15, b);    random_shuffle(b, b + 15); }

Thanks rdrake and wtd, both solutions work. 8 bits each.
