Why does my deposit feature only let me deposit 10,000 or less?

I created a bank app, and when I try to deposit money that is over 10,000, my error message that I set up displays, but any number under works.. I assume this has something to do with value types. I used int, however I tried double but can’t figure that out too.

/* FUNCTION DEFINITION */
void DepositMoney(int initialbalance, int deposit);

// Main Program
int main()
{
int initialbalance=10000;
int deposit;

cout << " \t ***** What you want to Do ??? Choose the Action character *****" << endl << endl;

            cout <<" \t   W : Money Withdraw" << endl
            <<"\t   D : Deposit" << endl //I CHOSE THIS ONE 
            <<"\t   B : Balance" << endl
            <<"\t   T : Transfer" << endl
            <<"\t   C : Change Details" << endl
            <<"\t   Q : Quit or Exit" << endl << endl ;

            string input;
            cin >> input;
            bool t=true;
                if (input=="W" || input=="w"){

                    cout<<"\n\t Your balance is: " << initialbalance<<endl;
                    cout<<"\n\t How much would you like to withdraw: ";
                    cin>> withdraw;


                   withdrawMoney(initialbalance, withdraw);
                   initialbalance -= withdraw;
                    t=false;

                }
                else if (input=="D" || input=="d"){
                    cout<<"\n\t Your balance is: " << initialbalance<<endl;
                    cout<<"\n\t How much would you like to deposit: ";
                    cin>>deposit;

                    DepositMoney(initialbalance, deposit);
                    initialbalance += deposit;
                    t=false;

// Function for Deposit
    void DepositMoney(int initialbalance, int deposit)
    {
    // Get how much user want to deposit and display balance after adding
                if(initialbalance < deposit)
                        cout <<"\n\t The amount you entered is not not valid."<<endl; //THIS MSG DISPLAYS
                    else
                        initialbalance += deposit;
                    cout<<"\n\t Your new balance is: " << initialbalance <<endl<<endl<<endl;
    }

I tried changing every data type that said int to double, but that didn’t even run the code.

>Solution :

When you call DepositMoney(), you have this check: if (initialbalance < deposit). At this point, initialbalance is 10000, so if the amount is greater, then you cannot deposit it. Based on the logic, you likely wanted a check like that in withdrawMoney(), not in DepositMoney().
