Question

Declare a struct type item for an item with weight and total price, both are of type float. Write a function maxval (x,y,z) to receive two items (x) and (y) and return the more valuable item , i.e. the item with the higher price per weight ratio.also write the main. in c++

Answer 1

#include <iostream>

using namespace std;

struct item{
   float weight;
   float totalPrice;
};

struct item maxval(struct item x, struct item y){
   if((x.totalPrice/x.weight) > (y.totalPrice/y.weight)){
      return x;
   }
   else{
      return y;
   }
}

int main() { 
   struct item x, y, z;
   
   x.weight = 4.5;
   x.totalPrice = 10;
   
   y.weight = 8;
   y.totalPrice = 20;
   
   z = maxval(x, y);
   
   cout<<"Max: weight="<<(z.totalPrice)<<", totalPrice="<<(z.weight)<<endl;
   
   return 0; 
}
