How to Programmatically Add Product to Cart in Magento 2
Sometimes, Magento 2 store admin needs to prefill the shopping cart with a product whenever a user lands to the website. There are many uses of this functionality; for example, the admin may require to add a virtual product to cart whenever a particular product is added to the cart by a customer, the admin may want to give away the free product by default, the admin requires to integrate a custom system or he may require to send visitors directly to the checkout with the product in the cart.
Default Magento 2 doesn’t allow this. So, I’ve come up with a method to programmatically add product to cart in Magento 2.

Where you assign customer to cart?
Hello Parbat Singh,
The above solution is to assign the product to the cart. You don’t need to assign customer because if the user is currently login, then the product will be assigned to his cart only.
Thanks.
