Naturally, we can also create a function to facilitate:Copy codeThe Code is as follows:> Moqi ('hello') ('World') ('phodal ')> "Hello, World Phodal"So there is such a function.Copy codeThe Code is as follows:Var Moqi = f

Why is this answer? Because the value type is stored in the memory

At the same time, I bought the book "post-standard budget management theory and practice for highway construction enterprises. As this department belongs to the business department and the enterprise quota and the target cost belong to the business department, the cost/quota database of an enterprise is being developed, so this book is worth learning from.
