Thread: C++ Fibonacci's Rabbits!!!!!

Hey, i wrote this program for fibonacci's sequence, it works, but im having a problem completing a modification of it, i want to write 2 programs , i have done the first , i need help on the second.

First problem: Write a program that accepts user input for the number of months, and computes the number of pairs of rabbits at that month. Use a for loop and within the for loop output the running total. (( ACCOMPLISHED ))

Second Problem: First problem: Write a program that accepts user input for the number of pairs of rabbits, and computes the minimum number of months it woud take to have that many pairs. Use a for loop and within the for loop output the running total.
(( NEED HELP ))

The C++ code is here:
