compile your code with following command
|
1 2 3 4 |
$ gcc main.c -l sqlite3 $ ./a.out Database Opened successfully Table STUDENTS created successfully |
You will also notice a SQLite database named student.db in the same folder containing you main.c file
|
1 2 |
$ ls a.out main.c student.db |
In student.db the STUDENTS table is created after running the code above. You can verify the schema of the student table in SQLite database by running following commands
