Flex and Bison Calculator -- 2

Add a file that it is a calculator, but it does not show the validations message you must design and implement a calculator using the programming tools taught in class (Flex and Bison) as follows: - Design a lexical analyzer that allows to recognize the lexemes of: Signed and unsigned integers. Example (5, 34, -100). Decimal numbers with and without sign. Example (.05, 0.51, -13.1, -3.1416). Variables (with the same regular expression used in flex practice). Variable types (int, double and string). Mathematical operators (=, +, -, *, / and%). The power operation is set as a function (Pow (Element, positive or negative integer);) Strings ("All symbols in double quotes"). End of expression symbol (;). Design a parser that allows you to recognize grammars for the following forms: or Declare a variable. Examples: - int var1; - double var2; - string var3; Declare and initialize a variable. Examples: - int var1 = 4; - string var3 = "hello world"; or Assign values to a variable or valid expressions. Examples: - var1 = 5; - var1 = integervar1 + integervar2 * floatingvar3; - var3 = "hello again"; Mathematical operations similar to bison practice, adding variab handling them previously declared in the grammar (operations can be between variables and values, whether they are integers, decimals and strings). - For chains only power operations. pow ("hola", - 2); results in alohaloh). Design a data structure that stores the declared variables, their data types, and values. Everything necessary will be added for the program to recognize “if” statements that return as TRUE or FALSE results depending on the condition. The structure of the instruction is as follows: if (CONDITION); Where the CONDITION must contain a relational operator (<,>, ==, <=,> =) between two expressions. Expressions can be constants or variables, integers or floats, it can even accept an operation as an expression. Examples: If (5 <6); // TRUE output If (var1 == 5); // Output depends on the value of the variable If (var1 <var2); // Output depends on the value of the variables If (var1> ”HelloWorld”); // Output Type error Validations: When using a variable in an operation, the variable must have been declared before use (Send error message). The same variable name cannot be declared twice (Send error message). Incompatible operations (operations between integers and decimals are allowed) between data types and variables (Send error message). Incompatible assignments (Send error message).
