a. Introduction : The goal of this project is to create a language mini-compiler described below, by performing the different phases of compilation: lexical, syntactic, semantic and generation of the intermediate code. a. Language Description:

The implemented functionalities are:

1- For the lexical part, the file: lexicalProjet.l is OK.

2- For the syntax part, the file: syntaxiqueProjet.y is OK.

3- For the ts.h file, it contains:

• The symbol table.
• The functions used for the semantic part.

4- For the semantic part, the error cases treated are:

• The size of the array <0.
• The index of an array if it is an IDF, must be of type integer.
• Non-type compatibility in the following cases: • Declaration of constants. • Assignments. • Formatting sign (not 100% optimized).
• Undeclared IDF.
• Double IDF declared.
• Undeclared library
• Declared double library
• Division by Zero. (Only in the case of a constant = 0).
• The incompatibility of the number of formatting marks with the number of IDFs in the read and write instruction.
