Tutorial #1, Hello World !
Read a file “hello?.txt” and generate different type of outputs.
Use cases
hello1
Read the “hello1.txt” file and send each line to “cout”.
hello2
Read the “hello2.txt” file and send each line to “cout”, with evenBoard and reverting odd and pair lines.
hello3
Read the “hello1.txt” file and send each line to “cout”, with evenBoard.
hello4
Read the “hello2.txt” and “hello4.txt” files and send each line to “cout”, with eveBoard and reverting odd and pair lines.
All this different behaviors, only with one executable, without recompiling the software…
Analysis
With “Evenja - complexity solved” making an analysis, is only drawing the “move” of the datas.
hello1
Read a file and send to cout.
Input : read file “hello1.txt”
Output : write to “cout”
hello2
Read a file send datas to a board, send grouped datas to concat, send to cout.
Input : read file “hello2.txt”
Board : group datas (lines) by two datas (evenja library default)
Prg : concat the lines
Output : write to “cout”
hello3
Read a file send datas to a board, with “followDestination” board behavior, send grouped datas to concat, send to cout.
Input : read file “hello3.txt”, with followDestination
Board : group datas (lines) by two (evenja library default)
Prg : concat the lines
Output : write to “cout”
hello4
Read two files send datas to a board, send grouped datas to concat, send to cout.
Onput : read file “hello2.txt” (fdoor_file.cpp)
Input : read file “hello4.txt”
Board : group datas (lines) by two datas by source file (evenja library default)
Prg : concat the lines
Output : write to “cout”
