Syntax-and-Semantic-Analyzer-in-bison

A minimal c compiler implementation in flex and bison

Our chosen subset of C language has following characteristics.

• There can be multiple functions. No two function will have the same name. A function need to be defined or declared before it is called. Also a function and a global variable cannot have the same symbol.
• There will be no preprocessing directives like include or define.
• Variables can be declared at suitable places inside a function. Variables can also be declared in global scope.
• All the operators used in previous assignment are included. Precedence and associativity rules are as per standard. Although we will ignore consecutive logical operators or consecutive relational operators like ‘a && b && c’ ‘a < b < c’.
• No break statement and switch-case.
