How to print increments vertically

Praydoh (4)
I'm stuck at this part of the program where I have to print the principal vertically and its rates as shown in this output. My program's output only prints out the inputted principal and its rates. What do I use to increase the increments vertically and print the rates?
Principal Interest Rate
0.070 0.075 0.080 0.085 0.090 0.095 0.100

This is a monthly payments program.

Enter the loan amount: $100000
Principal       Interest Rate

The loop on line 22 should be encompassed with another loop whose index is used to multiply the results of the inner loop and cout << endl;.
