Thread: Monthly Payment Program Help

I cant figure out why it won't print out the value for the month.
After it asks for my last value, it suddenly closes.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <string.h>
#include <ctype.h>

int main()

{
   int term;
    double rate, monthp, princ, months;
    
  rate = rate/1200.0;
    months =term*12.0;
  
  printf("Please enter the the principle on your payment: ");
    scanf("%lf", &princ);
    printf("Please enter the rate on your payment: ");
    scanf("%lf", &rate);
    printf("Please enter the term of your payment in years: ");
    scanf("%d", &term);
  
 
   
    monthp = ((rate + (rate/(pow((1 + rate),(months))-1))) * princ);

   
    
    printf("Monthly Payment is: %lf", monthp);
    
    
    
    
    
    getchar();
    return 0;
    }

3 times (ok?)

I tried putting in system("PAUSE"); after my last print command but i get a giant number.

I've compiled and ran other programs, but none had this kind of problem.
However, I tested the equation by testing some numbers out before and they came out to the correct answer and the last print command worked.

Thanks! 1 program down 2 to go! I'll be back...
