Thread: Multiple Inserts into SQLite

I have been given a program where the output of that program generates random results for a 100 rounds of 100 coin tosses. My aim is to get all of those H & T results (10,000) into SQLite for analysis. This will be done many times.
Round 1: TTTTTHHTHTTHHTTTHHTTTTTTTHHTTHHHHHHTTTHTHTTHHTTTHH HHHHTHTTTTHTHHTHTTTHTHTHTHTTHHTTTTTTHTHTTHHTTTTHTH
-
Round 99: TTHHHTHTHHTTTHHTTHTHTHTTHHHHHTHTTTTHHHHTHTHTHTHHHH TTTTTHTTHHHTTTTHTTHHHHTTTTTTHHTHTTHTTTTHTHHTTHHTHT
Round 100: THTHTHHHHHTTHTTTTTTTTTTTHTTHHTHHHTHHTHHHHTTHTHHTTH THTHHTTHHHTHTHHTHTTTTTHTHTTHHTHTHHHTHTHHTHTHHTTTHH
As a beginner, I have little knowledge how to do this, so I looked into what others have done. Apparently Multi-row INSERT is not supported. Some sources say the only way to insert several rows in a batch is use a Select statement. How would I achieve this?
Assuming the database and table is already created, what code could I use in a C program to insert all this data into SQLite?

Thank you.
