Ok, this code is driving me nuts. I have to use a function for calculating this assignment. Im not even done finishing writing the code, im not that good with functions but the code is pretty self explanatory. It just does a one of 2 calculations. I know im like only 5 mins away from completion. I just need help finishing it. Feel free to copy in text editor.

#include <iostream>
#include <cmath>

using namespace std;

//Function Prototype
double var( double, double, double, double );
int main()
{
int option;
double princ, interest, years, compound;
cout << "Enter a 1 to calculate a compound amount" << endl;
cout << "Enter a 2 to calculate an amount compounded continuosly" << endl;
cout << "Enter a 3 to exit the program" << endl;
cin >> option;


while (option < 1 || option > 3)
{
cout << "Error, please enter a 1, 2, or 3" << endl;
cin >> option;
}

switch(option)
{
case 1:
cout << "You selected compound amount" << endl;
cout << "Please enter the principle, interest rate, years, and compounds per year" << endl;
cin >> princ >> interest >> years >> compound;
cout << "The amount compounded " << compound << " times a year at an interest rate of " << interest
<< " for " << years << " is $" << endl;

break;
case 2:
cout << "You selected compound continuosly" << endl;
cout << "Please enter the principle, interest rate, years" << endl;
cin >> princ >> interest >> years;
break;
case 3:
cout << "Thank you" << endl;
return 0;
}
}

double var( double princ, double interest, double years, double compound )
{
double ans;
ans = princ * pow( 1 + (interest/compound), (compound * years);
return ans;
}


here is the error-

cp5.C: In function `double var(double, double, double, double)':
cp5.C:48: syntax error before `;' token
