c - Searching number without reminder -


what main problem in algorithm,i need find smallest positive number divided 1 20 out divider...

#include <stdio.h> #include <stdbool.h>  int main(int argc,char* argv[]) { int num,j=2; int savenum=20; bool flag = false; while(!flag) {     num = savenum;     while(num%j==0 && j<=20)     {         num /= j;         j++;     }     if(j>20)         flag = true;     else     {      savenum++;      j=1;     } } printf("done"); printf("%d",savenum); }

are missing printf see intermediate results are? might idea going on internally.

but don't understand you're trying solve. want result: 2*3*4*5*6*7*8*9*10*11*12*13*14*15*16*17*18*19*20?

because think that's computing. however, you'll overflow before there , iterating point take while.

if instead you're trying find smallest number divisible every number less or equal 20, may want revisit update of num /= j.

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
