: In function ‘int main()’:
:38: error: expected primary-expression before ‘else’
:38: error: expected `;' before ‘else’
:47: error: expected primary-expression before ‘else’
:47: error: expected `;' before ‘else’
CODE

using namespace std;


double Dep1= 250000;// Declare Variables

double Dep3= 10000;

double cash = 0;

int main()

  cout << "Deposit: "; // Enter Pounds as a Single Integer
  cin  >> cash;       //Read the Amount of Pounds

   {  if  ( cash > 50000);

    double cashIn  = cash / 100 * 3.20;
    double IntPaid = cashIn;
    cout << "Rate = "     << 3.20 << endl;
    cout << "Interest = " << IntPaid << endl;
  }
  {  
     else if (cash < 50000);
       double cashIn = cash / 100 * 3.16;
       double IntPaid = cashIn;
       cout << "Rate ="     << 3.16 << endl;
       cout << "Interest = "<< IntPaid << endl;
  }
  {  
     else if (cash <= 10000);

     double IntPaid = cashIn;
     cout << "Rate ="     << 2.76 << endl;
     cout << "Interest =" << IntPaid << endl;
   }

}


Hi could you tell me what is wrong with this code at all please as i keep getting the error message posted above-it is a programe that is meant to 'ask for a deposit sum and print out the interest rate and the total interest gained from the deposit. Three different interest rates are used and each one will calculate the rate dependent on the amount of cash deposit ie: Dep1 calculates the rate for sums between 50.000-250.000 etc. Any feedback will be greatly appreciated as this is an assignment thats due in this week. Thankyou very much. Tara200

if else statement should look like this:
CODE

if(something >= something2){
      //do something
}else if (somethinf > 0){
      //do something else
}

you have to take off the commas after the if and before the else statement and it should work

Two things based on this:

CODE
{  if  ( cash > 50000);

    double cashIn  = cash / 100 * 3.20;
    double IntPaid = cashIn;
    cout << "Rate = "     << 3.20 << endl;
    cout << "Interest = " << IntPaid << endl;
  }


Remove the semicolon after your if condition
It should just be:

CODE
if (powerLevel > 9000)


Also, don't put the brace BEFORE the if portion, it surrounds
all the statements that are processed when your statement
is true like this:

CODE
if (powerLevel > 9000)
{
   cout << "It's over 9000!";
   cout << "Arggh!";
}
