This few files are to demo sqlite3 basics in C++
Steps for Setup
1.download mingw and install http://mingw-w64.org/doku.php/download/mingw-builds
2.Update PATH ENV. VARIABLE with mingw bbin folder default -C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin
3.Download Sqlite3 source code from https://www.sqlite.org/download.html amalgamation for standalone library file so you can add it to your project
4.extract amalgamation files inside a folder and on CMD
gcc sqlite3.c -c Will generate sqlite3.o (-c is compile only, generating object file)
5.And you have sqlite.o object file which will work with your c++ projects when you compile the object file with it
g++ main.cpp sqlite3.o -Ipath\to\sqlite3 (path is -isqlite3 if the .o file is in the same directory)
6.all the other files work in a simillar manner.
