找到交易后的剩余余额
假设初始余额为余额和要借记的金额 X ，其中 X 必须是 10 的倍数，卢比 1.50 将被扣除作为每次成功借记的借记费用。任务是找到交易后剩下的余额，可以成功，也可以不成功。天平的精度为 2 个浮点。 举例:
Input: X = 50, bal = 100.50
Output: 49.00
Transaction successful
Input: X = 55, bal = 99.00
Output: 99.00
Transaction unsuccessful
进场:看交易能否成功。
- 在下列情况下，交易可以成功:
- x 是 10 的倍数，并且
- 该人在账户中至少有(X+1.50)卢比，即要提取的钱加上费用。
- 在任何其他情况下，交易都不会成功。
- 如果交易成功，则从余额中扣除(X + 1.50)金额并返还
- 否则就退回余额。
以下是上述方法的实现:
C++
// C++ program to find the remaining balance
#include <bits/stdc++.h>
using namespace std;
// Function to find the balance
void findBalance(int x, float bal)
{
// Check if the transaction
// can be successful or not
if (x % 10 == 0
&& ((float)x + 1.50) <= bal) {
// Transaction is successful
cout << fixed << setprecision(2)
<< (bal - x - 1.50) << endl;
}
else {
// Transaction is unsuccessful
cout << fixed << setprecision(2)
<< (bal) << endl;
}
}
int main()
{
int x = 50;
float bal = 100.50;
findBalance(x, bal);
return 0;
}
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to find the remaining balance
import java.util.*;
class GFG
{
// Function to find the balance
static void findBalance(int x, float bal)
{
// Check if the transaction
// can be successful or not
if (x % 10 == 0 && ((float)x + 1.50) <= bal)
{
// Transaction is successful
System.out.printf("%.2f\n", bal - x - 1.50);
}
else
{
// Transaction is unsuccessful
System.out.printf("%.2f\n", bal);
}
}
// Driver Code
public static void main(String[] args)
{
int x = 50;
float bal = (float) 100.50;
findBalance(x, bal);
}
}

Python 3
# Python3 program to find the remaining balance
# Function to find the balance
def findBalance(x,bal):
# Check if the transaction
# can be successful or not
if (x % 10 == 0 and (x + 1.50) <= bal):
#Transaction is successful
print(round(bal - x - 1.50, 2))
else:
# Transaction is unsuccessful
print(round(bal, 2))
# Driver Code
x = 50
bal = 100.50
findBalance(x, bal)

Output:
