    input/output

    currently wrote a bank account type code it compiles well but instead of givign a starting bank account of 40 when i run it it gives a starting bank account of 22 + the deposit. I also tryed usign a const for the starting bank account so i just did bank == 40. take a look at the code
    think im starting to get the hang of this another week or two practicing code n ill move up

    Code:
    #include <iostream>
    using namespace std;
    
    int main ()
    {
      int i;
      int bank;
      bank == 40;
      cout<<"You have 40 dollars in your account" << endl;
      cout << "Enter how much money you want to deposit: ";
      cin >> i;
      cin.ignore();
      cout << "You have " << bank + i <<" in your account "<< endl;
      cout << " and an interest rate of " << (bank + i) * .05 <<" per month "<< endl;
      cin.get();
    }

    Code:
      bank == 40;
    This statement has no effect. it just checks if bank is 40 and discards the result of the comparison.
    it should be
    Code:
      bank = 40;

    What? He just showed you.
    Code:
    bank==40
    Is comparing, not assigning the value of 40. You want to use
    Code:
    bank=40
    If this is going to be constant, use:
    Code:
    const int bank;
    Also, don't post stupid short statements, use the edit button for that.

    If this is going to be constant, use:
    Code:
    const int bank;
    Remember to initialize constants . . .
    Code:
    const int bank = 40;
