I need some help to write to a MySQL database using C++. any basic tutorial will be appreciated. I did google but couldn't find a beginner tutorial. I am sort of lost here. :(

— a very short, practical roadmap to go from zero to a working INSERT in C++ using MySQL. was right to point you at official documentation; is also right that reading the headers helps you understand the API surface. Below is a focused path and a tiny example you can compile and adapt.

Choose an API: for idiomatic C++ use MySQL Connector/C++; for a minimal C-style interface use the C API (libmysqlclient); for single-file local apps consider SQLite instead. Typical steps: install the connector for your platform, include the connector headers, link the appropriate library, open a connection, use prepared statements (never concat user input into SQL), commit when needed, then close and free resources.

Example using Connector/C++ (minimal, real-world pattern — use prepared statements and error handling):

#include <cppconn/driver.h>
#include <cppconn/connection.h>
#include <cppconn/prepared_statement.h>
#include <cppconn/exception.h>
#include <iostream>

int main() {
try {
sql::Driver driver = get_driver_instance();
sql::Connection con = driver->connect("tcp://127.0.0.1:3306", "user", "pass");
con->setSchema("testdb");
con->setAutoCommit(false);
sql::PreparedStatement *pstmt = con->prepareStatement("INSERT INTO people(name,age) VALUES(?,?)");
pstmt->setString(1, "Alice");
pstmt->setInt(2, 30);
pstmt->execute();
con->commit();
delete pstmt;
delete con;
} catch (sql::SQLException &e) {
std::cerr << "SQL error: " << e.what() << std::endl;
return 1;
}
return 0;
}

Build notes and gotchas: use the connector/library names provided by your package (on many Linux installs the C API flags come from mysql_config --cflags --libs; Connector/C++ often requires linking -lmysqlcppconn or the vendor-supplied library). Match connector version to your server/library headers, set the connection charset to utf8mb4 for emoji/multi-byte text, prefer prepared statements to avoid injection, and consult the connector docs for platform-specific install and thread-safety details (Connector/C++ docs).

I actually wanted a sample code to start on

You won't always find a laid out tutorial for you but a quick glance at the documentation will many times tell you enough for you to make your own samples.

Remember you can read header files too.

This is has a good c++ API for handling databases in the client's computer.
