CodeChef ATM Problem Code: HS08TEST
SOLUTION C++ :
#include<iostream>
#include<iomanip>
using namespace std;
int main() {
int a;
//a-amounttodebit
float b ;
float c;
std::cin >> a;
std::cin >> b;
if(( (a+0.50) < b) && ((a) % 5==0) ) {
c = b - (a+0.50) ;
cout<<fixed<<setprecision(2)<<c<<endl;
}
else {
//std::cout << b << std::endl;
cout<<fixed<<setprecision(2)<<b<<endl;
}
}QUESTION
Pooja would like to withdraw X $US from an ATM. The cash machine will only accept the transaction if X is a multiple of 5, and Pooja's account balance has enough cash to perform the withdrawal transaction (including bank charges). For each successful withdrawal the bank charges 0.50 $US. Calculate Pooja's account balance after an attempted transaction.
Input
Positive integer 0 < X <= 2000 - the amount of cash which Pooja wishes to withdraw.
Nonnegative number 0<= Y <= 2000 with two digits of precision - Pooja's initial account balance.
Output
Output the account balance after the attempted transaction, given as a number with two digits of precision. If there is not enough money in the account to complete the transaction, output the current bank balance.
Example - Successful Transaction
Input: 30 120.00 Output: 89.50
Example - Incorrect Withdrawal Amount (not multiple of 5)
Input: 42 120.00 Output: 120.00
Example - Insufficient Funds
Input: 300 120.00 Output: 120.00
