C++ program trouble

Hi,
I am a beginning student of C++ and I am having trouble with the whole programming process. Here's, my latest trouble I am now writing a program to calculate mortgage payment with interest rates from 6% to 10%, starting at 5 years to 30 years with 5 year increments. Formula: m = r*l*f / 12 *f / 12* (f - 1); where f = (1 + r/12) * 12*y.
Here is a sample of my code:

float r; //variable for interest rate
int l; //variable for loan amount
int y; //variable for the number of years
float mgt; //mortgage
int pow;
float f = pow((1 + r/12),(12 *y));
float f1 = pow((1 + r/12),(12*y-1));

for (r = .06; r <=.10; r++)
{
for(y = 5; y <=30; y++)

my trouble is when I compile and run my program I keeping get an error message relating to pow-term does not evaluate to a function. What does this mean?

Did you #include <math> in your program?

>>>int pow;


take that out.


put this in...

#include<cmath>
using namespace std;

+++++

for (r = .06; r <=.10; r++)

increment adds a whole integer 1. How is this going to work?

WTF? How has this thread been up for 20 minutes and already have 1500 views?

int pow; ?????
pow is a function in math.h

few things....first, pow is a function, don't need to initialize it....just include the math.h library...second, for your for loop, your going to have to do an r+=.01 instead of r++....each time the loop operates, itll had 1.0, not .01 like you want it to.
