Objectives :

• myAlgo_set_difference1.cpp
  first series prevailed over the second
  setdiff = set_difference ( v1.begin ( ) , v1.end ( ) ,
  v2.begin ( ), v2.end ( ) , vDiff.begin ( ) );
• Code: myAlgo_set_difference1.txt
• also see :
  • myAlgo_symmetric_difference1.htm,
  • myAlgo_set_intersection1.htm

Step: 1 Create a source file.

Step: 2 Edit and save Source file

Step: 3 Runtime Views: FYI, when an element in the first series was in ascending sequence, the element in the first was recognized; if not in an order (bottom illustration), would be dropped out.
