How come my solution only multiples 0.4 not 0.5?Under AccountType 'C' or AccountType'c'

Please use tags.

I have fancied it up a little (tags, indenting etc...) and here's what I think is wrong (the //commented parts ) (I'm fairly new, hence the "what I think")

# include <string> // I haven't seen any strings in the code, so...
using namespace std;

int main()

{ 
    int accountnumber, saving_minimum_balance, checking_minimum_balance, saving_fee,
    checking_fee, balance;
    double checking_interest, saving_interest, special_checking_interest;
    char accountType;
    
    checking_interest=.03, saving_interest=.04, special_checking_interest=.05,
    saving_fee=10, checking_fee=25; 
    // declaring variables and initializing them are different, in declaring, you can do
    //int var1, var 2, var3;
    //In initializing them, you cannot seperate by a comma, you must use a semi colon
    //var1 = 0; var2 = 2; var3 = 7986; etc...

    cout<<"please input your account number"<<endl;
    cin>>accountnumber;
    cout<<endl;

    cout<<"Enter account type:"<<endl;
    cout<<"S or s (Saving),"<<endl;

    cout<<"Enter minimum balance:"<<endl;

    if((accountType='s'|| (accountType='S')))// why all the brackets? Also ==, not =
    //you need a pair of braces, {}, to enclose the following in this if statement
    if(balance>=saving_minimum_balance)
    {

        cout<<"Current balance:"<<balance<<endl;
    }
    else if(balance<saving_minimum_balance)
    { 
        balance=(balance-saving_fee);
        cout<<"Current balance:"<<balance<<endl;
    }
    else if((accountType='c'|| (accountType='C'))) //again with the brackets and the ==, not =
    //again with the braces, {}
    if(balance>=5000)
    { 
        balance=(balance*special_checking_interest);
        cout<<"Current balance:"<<balance<<endl;
    }
    else if (balance<=5000)
    { 
        balance=(balance*checking_interest);
        cout<<balance<<endl;
    }
    else if(checking_minimum_balance<=5000)
    { 
        balance=(balance-checking_fee);
        cout<<balance<<endl;
    }

    std::cin.get();//why std::
    std::cin.get();//why std::

    return 0;
} 

It's late and I'm tired, so there's likely more, but this should hopefully be a start.
