Tcecarenko [31]3 years ago

Answer:

FOR i% = 1 TO 100

 IF ((i%\3) = i%/3) AND ((i%\7) = i%/7)  THEN

   PRINT i%

 END IF

NEXT i%

Explanation:

Of course using MOD would be cleaner, but another way to check if a number is integer divisable is to compare the outcome of an integer division to the outcome of a floating-point division. If they are equal, the division is an integer division.

The program outputs:

21

42

63

84

A method countDigits(int num) of class Digits returns the remainder when the input argument num(num > 0) is divided by the nu
sertanlavr [38]

Answer:

#include <iostream>

using namespace std;

class Digits

{

   public:

   int num;

   int read()       //method to read num from user

   {

       cout<<"Enter number(>0)\n";

       cin>>num;

       return num;

   }

   int digit_count(int num)  //method to count number of digits of num

   {

       int count=0;

       while(num>0)    //loop till num>0

       {

           num/=10;

           count++;   //counter which counts number of digits

       }

       return count;

   }

   int countDigits(int num)   //method to return remainder

   {

       int c=digit_count(num); //calls method inside method

       return num%c;  

   }

};

int main()

{

   Digits d;    //object of class Digits is created

   int number=d.read();   //num is read from user

   cout<<"\nRemainder is : "<<d.countDigits(number);  //used to find remainder

   return 0;

}

Output :

Enter number(>0)

343

Remainder is : 1

Explanation:

As program is missing to find errors , a logically write program is written to find the remainder when a number is divided by its number of digits. A class  Digits is constructed which has public variable num and methods read(), digit_count(), countDigits().

  • read() - This method reads value of num from the user and return num.
  • digit_count() - This method takes a integer as parameter and counts the number of digits of a number passed as argument. while loop is used to increement the counter until num<0. This returns the value of count.
  • countDigits() - This method takes a integer as a parameter and returns remainder when the argument is divided by number of  digits of argument. Number of digits is calculated by using method digit_count().

At last in main method , object of Digits class is created and its methods are used to find the output.

b. arsort()

this is also sorting function, it used to sort the associated array in descending order according to the value.

d. asort()

Information that has been analyzed and refined so that it is useful to policymakers in making decisions; specifically, decisions
denis-greek [22]

Answer:

Intelligence

Explanation:

Intelligence is the product resulting from the collection, collation, evaluation, analysis, integration, and interpretation of collected information. It is a specialised information product that provides an adversary with information required to further its national interests. One of the most important functions of intelligence is the reduction of the ambiguity inherent in the observation of external activities.rations.  

In most cases, the development of an intelligence product involves collecting information from a number of different sources. In some cases, information may be disseminated immediately upon collection based upon operational necessity and potential impact on current operations.

Strategic intelligence provides policy makers with the information needed to make national policy or decisions of long-lasting importance. Strategic intelligence collection often requires integrating information concerning politics, military affairs, economics, societal interactions, and technological developments. It typically evolves over a long period of time and results in the development of intelligence studies and estimates.

Operational intelligence is concerned with current or near-term events. It is used to determine the current and projected capability of a program or operation on an ongoing basis and does not result in long-term projections. Most intelligence activities support the development of operational intelligence.
