My program cant run accountType as a variable :         #include <iostream>
        #include <iomanip>
        using namespace std;
        int main ()
        {
    	int accountNumber;
	    float minimumBalance, currentBalance;
	    char accountType;

	    const float SAVINGS_SERVICE_CHARGE = 10.00;
	    const float CHECKING_SERVICE_CHARGE = 25.00;
	    const float SAVINGS_INTEREST_RATE = 0.04;
	    const float CHECKING_LOW_INTEREST_RATE = 0.03;
	    const float CHECKING_AVERAGE_INTEREST_RATE = 0.05;

	    cout <<"Please the details of your account"<< endl;
	    cin >> accountNumber,accountType,minimumBalance,currentBalance;

	    switch (accountType){

	    case 's':
	    case 'S':
		cout <<"Account number"<<accountNumber<<endl;
		cout <<fixed<<showpoint<<setprecision(2);
		cout <<"Account type:Savings"<<endl;
		cout <<"Minimum Balance: $"<<minimumBalance << endl;
		cout <<"Current Balance: $"<<currentBalance << endl;

		if (currentBalance < minimumBalance) {

		else {
