Enter amount of stock sold: 25
Display stock amount at end of the day: 5

Answer 1

//Since the language is not specified , i have written the code in C++, if needed can write in java

Code in C++ :

#include <iostream>
using namespace std;

int stockLevelForCurrentDay(int initialStock,int amountBought,int amountSold) //function definition to calculate stock level
{
  
return initialStock+amountBought-amountSold; // remaining stock = current stock + stock bought - stock sold
}

int main() {
  
   int initialStock,amountBought,amountSold;// declare 3 variable to get the input from the user
  
   cout<<"Enter stock at start of day:\n";
   cin>>initialStock; //read input for initialStock
  
   cout<<"Enter amount of new stock received today:\n";
   cin>>amountBought; //read input for amountBought
  
   cout<<"Enter amount of stock sold:\n";
   cin>>amountSold; //read input for amountSold
  
   int stockLevel = stockLevelForCurrentDay(initialStock,amountBought,amountSold); //call function and store the result
  
   cout<<"Display stock amount at end of the day: "<<stockLevel; //print the result
  
   return 0;
}
