Answer:
<u>720</u> possible PIN can be generated.
Explanation:
To calculate different number of orders of digits to create password and PIN, we calculate permutation.
Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:
nPr = n!/(n-r)!
there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)
So in question we need to calculate
P=?
where
n= 10 (0-9 means total 10 digits)
r= 3 (PIN Consist of three digits)
So by using formula
10P3 = 10!/(10-3)!
=10!/7!
= 10x9x8x7!/7!
= 10x9x8
= 720

Answer:
The program in C++ is as follows:
#include <iostream>
using namespace std;
int main(){
int qty;
float discount = 0;
cout<<"Quantity: ";
cin>>qty;
int cost = qty * 100;
{
; }
cout<<"Cost: "<<cost - discount;
return 0;
}
Explanation:
This declares the quantity as integer
int qty;
This declares and initializes discount to 0
float discount = 0;
This prompts the user for quantity
cout<<"Quantity: ";
This gets input for quantity
cin>>qty;
This calculates the cost
int cost = qty * 100;
If cost is above 1000, a discount of 10% is calculated
{
; }
This prints the cost
cout<<"Cost: "<<cost - discount;
