if possible give some sample examples

#7

I want to generate array which should contain fix amount of bits as 1 given by user …
Ex :- say array of size 10 with 4 set bits then output should be
1000100110

And every time array generate random set of bits with given fix amount of set bits

i.e.
1000101010
Next time it might be
0000110110

ok ,so u can do like this->

generate all such number(binary array) that are having required number of set bits ,store then in array or vector.

now use random function to randomly pick any index of the generated array and then simply return that number(binary array)
