How to use the biggest value?

[PhtCreator]

Hi! I'm a beginner.

I have 4 main values: k = 355; 1var; 2var; 3var; - random values
And the main object comes with 3 steps:

1.Finding biggest value;
2.Arranging;
3.Final - output;

The objective is to find the biggest value (that what this program does) and if
we find out that: k - (BoxN*144) or (BundleN*12) or PairN != 0; Then program has to go back to the process of number arranging without the value that was the biggest;
At the end result should be: Box number:2; Bundle number: 5, Pair number: 7;

Simple as that! But sadly I'm not experienced enough to solve this.


For more details this program is about buying boxes (*aoi = BoxN*144),
bundles (*aoi = BundleN*12),
or pairs of socks (*aoi = 1)
And the goal is to buy them most efficient way; If you can't use the most efficients way**, then use second as much efficient way, it is determined from values - var1, var2, var3;

*aoi - amount of items in it is calculated by:
**can't use because of the too big amount of number is being buyed e.x. need to buy 12 items so it can't be done with a box, because we buy 144-12=132 too many of it.

#include <iostream>
#include <math.h>
#include <iomanip>
using namespace std;

int main(){
   int k = 355, //total number
   x = 1, //useful in arranging
   nb = 144, //number in box
   nbun = 12, //number in bundle

   var1 = 59, //random number
   var2 = 84, //random number
   var3 = 144; //random number

    //Finding biggest value

    int array[3] = {var1, var2, var3};
    int temp = 0;

    for(int i=0;i<3;i++)
    {if (array[i]>temp) {temp=array[i];}}

//arranging

int BoxN = 0, BundleN = 0, PairN = 0;

    if (var3 == temp){
    while (k - x * nb >= 0)
    {
        x = x + 1;
        BoxN = BoxN + 1;

    }
    }
    else if (var2 == temp){
    while (k - x * nbun >= 0)
    {
        x = x + 1;
        BundleN = BundleN + 1;
    }
    }
    else {
    while (k - x * 1 >= 0)
    {
        x = x + 1;
        PairN = PairN + 1;
    }
    }

//final

cout << "Box number: " << setw(7) << fixed << setprecision(0) << BoxN << '\n';
cout << "Bundle number: " << setw(4) << fixed << setprecision(0) << BundleN << '\n';
cout << "Pair number: " << setw(6) << fixed << setprecision(0) << PairN << '\n';
return 0;
}
