Can't fix warning- some input...

Got a warning...like to fix...(I know warning are generally fine...but want to fix)- In bold

20 C:\Documents and Settings\HP_Owner\Desktop\PA2C.cpp [Warning] passing `double' for converting 3 of `double futureInvestmentValue(double, double, int)'

Code:

---

#include <iostream>
#include <cmath>
using namespace std;

double futureInvestmentValue(double IA, double MIR, int NOY);

int main()
{
  double investmentAmount, annualInterestRate, numOfYears,  monthlyInterestRate, futureValue;
 
  cout << "Enter investment amount: ";
  cin >> investmentAmount;
  cout << "Enter monthly interest rate: ";
  cin >> annualInterestRate;
  cout << "Enter number of years: ";
  cin >> numOfYears;

  monthlyInterestRate = annualInterestRate / 1200;
 
  futureValue = futureInvestmentValue(investmentAmount,monthlyInterestRate,numOfYears);

  cout << "Future value is " << futureValue << endl;
 
  return 0;
}
double futureInvestmentValue(double investmentAmount, double monthlyInterestRate, int numOfYears)
{
    double accumulatedValue; 
   
    accumulatedValue = investmentAmount * pow(1 + monthlyInterestRate, numOfYears * 12);
   
    return accumulatedValue;
}

we enginners bother only about errors not WARNINGS !!!!!!!!!!!!!!!!!!!



so ignore it

...
sorry i didnt read your post

It is a warning, so you can ignore it. But the problem is that you have said that numOfYears is a double, when the futurInvestmentValue function is asking for an int.

Your third parameter 'numOfYears' to the function is supposed to be an int, but you pass it a double

Code:

---

double investmentAmount, annualInterestRate, numOfYears,  monthlyInterestRate, futureValue;

---

So you get an implicit type conversion

Floating to Integral (C++)
Standard Conversions (C++)

You're not an engineer then.

All warnings are errors.

If you have warnings, you're on the slippery slope of seeing "how much can I get away with before it breaks".
One or two is OK (usually), but by the time you're up into the 1000's, you've got a big-assed problem on your hands.

What's worse, with 1000's of warnings, you just don't see 1001 appear as one you REALLY should be paying attention to.

Thanks got the warning fixed...
