### mortgage program

I'm trying to do this chart in c++ and i'm stuck.

Principle= 150,000.00 rate= 6% 0.005
Payment= 6,648.10 Years= 2 24

Here's my code , can anyone help?

What's the reason for the for loop if you calculate all the elements by hand? What would you do if you need to pay for 30 years?
i was just throwing things out there, i don't understand why the loop doesn't keep going.
 ``12345678910111213141516171819202122232425262728`` ``````#include int main(void) { int years, months, index; double principle, rate, interest, dolPrin, princBalance, payment; printf("Hello, this program calculates a payment plan for your loan and display every month's information.\n"); printf("Ok, to start we will need to ask you a few questions.

The reason your thing was not working is that you initialize elements in the array up to index 5, but then, when the index is 6, on line 37, prinBalanceA[index] is not defined
