onnx c++ demo

ONNX (Open Neural Network Exchange) is an open standard for representing machine learning models that enables models to be trained in one framework and transferred to another for inference. C is a high-level programming language that is widely used for developing various applications.

There is no specific "ONNX C demo", but you can find examples of how to use ONNX in C-based projects. One approach would be to use a library such as ONNX Runtime, which provides an inference engine for ONNX models. You can find some examples and tutorials on the ONNX Runtime GitHub repository, including a "getting started" guide and code samples in C.

Keep in mind that while C is a powerful language, it may not be the best choice for developing complex machine learning models. More commonly, machine learning models are developed in Python using popular libraries like TensorFlow, PyTorch, or Keras, and then exported to ONNX for deployment to production environments.
