Problems with compound interest program

[JordanLy]

[b]Hey all,

I'm slowly but surely learning C++ and keep on getting compiling errors. So, I check my work in an online compiler. After it checks I tweak my code in netBeans and it still doesn't work. Most recently I wrote this:

#include <iostream>
#include <cmath>

using namespace std;
int main() {

int iTime;
double dRate
double dPrinciple;
double dTotal;

cout <<"Investment cash: ";
cin >> dPrinciple;

cout <<"\nWhat is the rate: ";
cin >> dRate;

cout <<"\nHow long (in years):";
cin >> iTime;

dRate /= 100;
dTotal= dPrinciple*pow((1+dRate), iTime);
cout << dTotal ;

return 0;
}

And I get this error message:

"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf

Do you have any suggestions?

[Dy7SLyTq]

you need a semicolon on line 8

Thanks for your help. I tried another simpler program, but it still won't compile:

Program:

#include<iostream>
using namespace std;

int main()
{
cout << "Hello";
return 0;
}

I think it's my compiler. I've copied programs word for word that work and they still wont compile. Am I missing a tool or file?
