Pernicious numbers | Rosetta Code | #15
URL to the problem page: http://rosettacode.org/wiki/Pernicious_numbers A pernicious number is a positive integer whose population count is a prime. The population count is the number of ones in the binary representation of a non-negative integer. Example 22 (which is 10110 in binary) has a population count of 3, which is prime, and therefore 22 is a pernicious number. Display the first 25 pernicious numbers (in decimal). Display all pernicious numbers between 888,888,877 and 888,888,888 (inclusive). #include <iostream> using namespace std ; int main () { int cnt = 0 , cnt2, cnt3, tmp, binary [ 8 ]; cout << "First 25 pernicious numbers are:" << endl; for ( int i = 3 ; cnt < 25 ; i++) { ...
