Last month Joe purchased some stock in Acme Software, Inc. Here are the details of the purchase: The number of shares that Joe purchased was 1,000. When Joe purchased the stock, he paid $45.50 per share. Joe paid his stockbroker a commission that amounted to 2% of the amount he paid for the stock Two weeks later Joe sold the stock. Here are the details of the sale: The number of shares that Joe sold was 1,000. He sold the stock for $56.90 per share. He paid his stockbroker another commission that amounted to 2% of the amount 
he received for the stock.
Write a C program that displays the following information: The amount of money Joe paid for the stock. The amount of commission Joe paid his broker when he bought the stock. The amount that Joe sold the stock for. The amount of commission Joe paid his broker when he sold the stock. Display the amount of profit that Joe made after selling his stock and paying the two 
commissions to his broker. (If the amount of profit that your program displays is a negative number, then Joe lost money on the transaction.)

Answer 1

#include <stdio.h>

int main()
{
   int num_of_stocks = 1000; // number of shares
   double cost = 45.50; // cost of each share
   double total_cost = cost*num_of_stocks; // total cost of shares
   double buy_commision = total_cost*0.02; // buying commission
   double buy_amount = total_cost + buy_commision; // total amount Joe paid

   double sold = 56.90; // selling price of each share
   double money_received = num_of_stocks*sold; // money Joe get after selling
   double sold_commision = money_received*0.02; // money Joe paid to broker
   double final_amount = money_received - sold_commision; // in-hand money of Joe

   printf("Joe bought stock for $%.2lf ", total_cost);
   printf("Joe paid commission when buying: $%.2lf ", buy_commision);
   printf("Joe sold stock for $%.2lf ", money_received);
   printf("Joe paid commission when selling: $%.2lf ", sold_commision);
   printf(" Final Money Joe received: $%.2lf ", final_amount-buy_amount);

   return 0;
}
