The document describes a C program that finds subsets of a given set of positive integers whose sum equals a target value. The program takes a set of integers, adds them up, and uses backtracking recursion to find all subsets that sum to the target value. If no matching subset exists, it displays a message. It provides an example input of the set {1, 2, 5, 6, 8} and target 9, which has the two solutions {1, 2, 6} and {1, 8}.
