To findout smallest and largest numbers from text file

[bioinformatic]

Pl guide me how to write a complete programme to findout a smallest and largest number from given problem:
e.g.
200
250
120
5
28
30

Read them from a file with an ifstream ( http://www.cplusplus.com/doc/tutorial/files/ ) and store them into a std::vector. Then set the smallest and largest variables to the first element in the vector and loop through the remaining elements comparing them to those two variables and reassigning when they're less than smallest and greater than largest.
