help....reading numbers from file and arranging them

[jay101]

hey guys, i'm new in c++ programming. i need help with C++ code with functions to read from a text file a sequence of numbers of arbitrary length and print out only positive numbers belonging to the sequence in increasing order. For example 21, 12, 44, 21, -5, 63, 0, to be printed out as 12, 21, 21, 44, 63.

i'll really appreciate your help
