#include <stdio.h> #include <math.h> void printPowerSet(char *set, int set_size) { /*set_size of power set of a set with set_size n is (2**n -1)*/ unsigned int pow_set_size = pow(2, set_size); int counter, j; /*Run from counter 000..0 to 111..1*/ for(counter = 0; counter < pow_set_size; counter++) { for(j = 0; j < set_size; j++) { /* Check if jth bit in the counter is set If set then print jth element from set */ if(counter & (1<<j)) printf("%c", set[j]); } printf("\n"); } } /*Driver program to test printPowerSet*/ int main() { char set[] = {'a','b','c'}; printPowerSet(set, 3); return 0; }

The code above is an example of how to print all the subsets of a set.
