For bad software, probably a virus/malware/ransomware kind of thing. If it is good software, probably a program that organizes your files, adjusts certain things, but do not record your files (no programs are at the top of my head, sorry).
Answer:
#here is code in python.
#read number of shares
num_share = int(input("Enter number of shares:"))
#read purchase price
buy_p = float(input("Enter purchase price:"))
#read sell price
sell_p = float(input("Enter sale price:"))
#total buying cost
buy_cost=buy_p*1.03*num_share
#total selling cost
sell_cost=sell_p*0.97*num_share
#if net profit
if(sell_cost>buy_cost):
print("After the transaction, you made " +str(sell_cost-buy_cost)+ " dollars.")
#if net loss
else:
print("After the transaction, you lost " +str(buy_cost-sell_cost)+ " dollars.")
Explanation:
Read the total number of shares from user.Then read buying price of a share and selling price of a share.Then calculate total buying cost including commission.Calculate total selling cost excluding the commission.If total buying cost is greater than total selling cost the print the profit else print the loss in the transaction.
Output:
Enter number of shares:10
Enter purchase price:10
Enter sale price:10
After the transaction, you lost 6.0 dollars.
Answer:
Follows are the method definition to this question:
void Reverse_Order(struct Node* h)//defining a recursive method Reverse_Order that takes structure in parameter
{
if (h == NULL)//use if block to check head equal to null
return;//use return keyword
Reverse_Order(h->next);//call method recursively
cout<<h->data;//print data
}
Explanation:
In the above code, a recursive method "Reverse_Order" takes structure as the parameter, and inside the method, structure variable h is used that uses the if conditional statement to check the header equal to null.
In the condition is true, it will use the return keyword, and in the next step, it calls the method recursively, and print its value in the reverse order.
