name. After successful matching, the offset of the file in SD is obtained. The 9-bit offset (512 bytes, one sector) is the position of the file. Fopen returns a handle that corresponds to a data structure. The structure generally includes the start position, length, and current read pointer position of the file. The record start position and length are used to prevent cross-border reading. 6. fread The read operation is performed based on the current read pointer of the handle, and the cu

class, where each terminator in the expression produces a Varexpression object in the stack.Nonterminalexpression Non-Terminator expressionEach rule in the grammar corresponds to a non-terminating expression, and our example is that the addition and subtraction rules correspond to the two classes of addexpression and subexpression respectively. The non-terminator expression increases according to the complexity of the logic, in principle each grammar rule corresponds to a non-terminator express
