i want to generate all the subsets of size k from a set. eg:-say i have a set of 6 elements, i have to list all the subsets in which the cardinality of elements is 3. I tried looking for solution,but those are code snippets. Its been long since I have done coding,so I find it hard to understand the code and construct a executable program around it. A complete executable program in C or C++ will be quite helpful. Hoping of an optimal solution using recursion. Thanks in advance. Kumar.

Maybe we can add a short blurb/description about each book that you have personally read / benefited from. Feel free to debate… >>> More
