  - Walk the AST to find the IASTName representing the name
    "c" in the expresion "c=  10".
  - Call IASTName.resolveBinding() on it to obtain an IBinding
     representing the variable "c".
  - Call IASTTranslationUnit.getDeclarationsInAST(IBinding) to
     get a list of AST nodes representing declarations of the
     variable. The IASTTranslationUnit can be obtained from any
     IASTNode via IASTNode.getTranslationUnit().

Hope that helps,
