redis bitcount example not working -


i playing redis , tried bitcount example: http://redis.io/commands/bitcount .

127.0.0.1:6379> set mykey "foobar" ok 127.0.0.1:6379> bitcount mykey (error) err unknown command 'bitcount'

my redis version follows:

mohit@mohit:~$ redis-server --version redis server v=3.0.1 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 build=ecf41ef76feca5d mohit@mohit:~$ redis-cli --version redis-cli 3.0.1

i verified website, 3.0.1 latest stable version. went wrong in arrangement?

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
