I am practicing about c++ using functions. but im stuck on the 1st question in the book about zeros.

can any1 help me so that i can study your codes. im a beginner in c++

 

tenx

 

the input must be

Thank you for your reply sir..but your code is too advance for me. i am stuck with the C++ functions. and I cant proceed to higher c++ if i'm confuse with functions... i just know the stdio.h, conio.h, stdlib.h, math.h.BTW: thank you for the reply sir..
