Question

Write a C++ program that will calculate how much of a profit an investor will make. You will need to ask the user for the following three inputs: • The number of shares the investor purchased. The price of the stock (per share) when the investor purchased it. The price of the stock (per share) now. The formula to use: Profit = (# of shares Current Price) - (# of shares * Purchase Price) Output this message to the screen: You have made a profit of $ XXXX.XX dollars since you bought xxx shares of this stock. Help#1: When you are writing a program, you always need to analyze the question and figure out what variables you need to store the data and what the data types are of those variables. Help#2: How to display the dollar amount formatted to two decimal places? 1. Include header file iomanip.h in your program. You will have the following two header files in your program: #include<iostream> #include<iomanip> 2. Place the statement at the beginning of the code in main() function body. cout << fixed << setprecision(2);

Answer 1

#include<iostream>
#include<iomanip>
using namespace std;

int main(){
   cout<<fixed<<setprecision(2);   //to set floating point max 2 value after point
   long int num_shares_purchased;   //to store number of shares purchased
   double curr_price;   //to store current price
   double purcha_price;   //to store purchase price
  
   cout<<"Enter number of shares purchased : ";
   cin>>num_shares_purchased;   //asking and entering total shares purchased from user
   cout<<"Enter purchase price of the stock : ";
   cin>>purcha_price;   //asking and entering purchase price
   cout<<"Enter current price of the stock : ";
   cin>>curr_price;   //asking and entering current price
  
   double profit = (num_shares_purchased*curr_price)-(num_shares_purchased*purcha_price);   /*calculating profit as per given formula*/
   //printing result in a formatted way
   cout<<"\n\nYou have made a profit of $ "<<profit<<" dollars since you bought "<<num_shares_purchased<<" shares of this stock.\n";   
}

//Output

C:\Users\AdiShakti NavDurga\Desktop\share.exe Enter number of shares purchased : 20 Enter purchase price of the stock : 2000 Enter current price of the stock : 2400 You have made a profit of $ 8000.00 dollars since you bought 20 shares of this stock.
