in those cases you need to provide an example input/output

please bother yourself to read the warnings 
foo.cpp: In function ‘int main()’:
foo.cpp:32:27: warning: ‘month’ is used uninitialized in this function [-Wuninitialized]
foo.cpp:33:30: warning: ‘rate’ may be used uninitialized in this function [-Wmaybe-uninitialized]
foo.cpp:34:28: warning: ‘bal’ may be used uninitialized in this function [-Wmaybe-uninitialized]
foo.cpp: In function ‘void words(std::ostream&)’:
