The attached program (PointersStringsAssignment.cpp) is a program tat has 6 parts (functions) named Demo01 ~ Demo06) There is a block of comments at the beginning of each function which are the instructions to complete that function

assignment

1. complete demo04

2. choose any two other functions and complete them
