I c + + white, beginner to STL, could you tell me how to do this problem? Can be complete code, very grateful!
Given a string, converted to another string, each rule is composed of two parts: a word may appear in the input file and a phrase used to replace it, express the meaning of is, when the first word in the input, we will he replaced with corresponding phrase,
Word conversion file rules are as follows:
BRB - & gt; Be right back
K - & gt; okey?
Y - & gt; According to
R - & gt; All
U - & gt; You
PIC - & gt; Picture
THK - & gt; thanks!
R - 18 & gt; Later
Hope to convert the content to:
Where r u
Y dont u send me a PIC
THK 18 k r
Note: using the map to complete this topic,

To replace and replace with the map after relationship established, and then read from the file, keyword to replace
