Question

CODE MUST BE IN C++ (please use for loop)
write a program that loops a number from 1 to 10 thousand and keeps updating a count variable (count variable starts at 0 ) according to these rules:

n1 = 14
n2 = 54
n3 = 123

if the number is divisible by n1, increase count by 1
if the number is divisible by n2, increase count by 2
if the number is divisible by n3, increase count by 3
if none of the above conditions match for the number, increase count by the number.

The program must produce one numeric output (it should be the value of count)

Answer 1

LOOK AT THE CODE AND COMMENTING FOR BETTER UNDERSTANDING.

SCREENSHOT OF THE CODE IS:

The output of above program is:

code for copy:

#include<iostream>
using namespace std;
int main()
{
    //declare all the variables
    int n,count=0,n1=14,n2=54,n3=123,i;
    //for loop ranges from 1 to 10000
    for( i=1;i<=10000;i++)
    {
        // modulo operator used to check whether the number(i) is divisible by n1 or not.if  divisible increment count by 1
        if (i%n1==0)
        {
            count+=1;
        }
        // modulo operator used to check whether the number(i) is divisible by n2 or not.if divisible increment count by 2
        if(i%n2==0)
        {
            count+=2;
        }
        // modulo operator used to check whether the number(i) is divisible by n3 or not.if divisible increment count by 3
        if(i%n3==0)
        {
            count+=3;
        }
        // if all the above cases fail then increment the count by number(i)
        if(i%n1!=0 && i%n2!=0 && i%n3!=0)
        {
            count+=i;
        }
    }
    //print the count to output screen
    cout<<"The value of count is : "<< count <<endl;

}
