Thread: If else /else if problem

Ok so, I feared this would happen when I compiled and ran, and surely enough it did.
I'm getting a logical error within this program and i cant figure out how to fix it. I want to make it so that when I enter any of the numbers between 0 - 19, 20 - 39, 40 - 59, or 60+, it will only do the calculation of the entered number by the specific decimal value assigned to that group of numbers. Take a look at my code and you'll understand what im talking about

Code:

#include <iostream>
using namespace std;


int main()
{
	

	double checkAmount;
	int monthBankCharge = 10;
	cout << "Enter the amount of checks you've written in the past month\n"; 

	cin >> checkAmount;

	if (checkAmount < 20)
	{ cout << checkAmount * 0.10 << endl;}

	else if (checkAmount >= 20)
	{ cout << checkAmount * 0.08 << endl;}

	else if (checkAmount >= 40)
	{ cout << checkAmount * 0.06 << endl;}

	else if (checkAmount >= 60)
	{ cout << checkAmount * 0.04 << endl;}


 
 system("pause");
	return 0;
}

If checkAmount == 43 then the first if(checkAmount < 20) will not execute but since 43 > 20 the next if statement will execute and the rest of the statements will be skipped. You may want to rearrange your else if clauses. Maybe switch the >= 20 with >= 60.

The question says:

A bank charges $10 per month plus the following check fees for a commercial checking account:
$0.10 each for fewer than 20 checks
$0.08 each for 20-39 checks
$0.06 each for 40-59 checks
$0.04 each for 60 or more checks

write a program that asks for the number of checks written during the past month, then computes and displays the bank's fees for the month.

never mind I finally figured it out. Thanks to all that helped (:
