must be done in C++, please and thank you

Write a C++program that uses a while loop (no math function allowed!) that accepts two positive integers n and m from the user and computes the smallest value of k so that nk>m or reports that this is impossible. E.g, if the user gives n=2 and m=8, then k is 4 since 24=16>8. If the user gives n=3 and m=3, then k is 2 since 32=9>3. If the user gives n=1 and m=2, then this is impossible. If the user gives n=1 and m=1, then this is also impossible
