Compiler Design GTU Practicals

Compiler Design

• Practical 1:

  Design a lexical analyzer for given language and the lexical analyzer should ignore redundant spaces, tabs and new lines. It should also ignore comments. Although the syntax specification states that identifiers can be arbitrarily long, you may restrict the length to some reasonable value. Simulate the same in C language.

  View

• Practical 2:

  Write a C program to identify whether a given line is a comment or not.

  View

• Practical 3:

  Write a C program to test whether a given identifier is valid or not.

  View

• Practical 4:

  Write a C program to simulate lexical analyzer for validating operators.

  View

• Practical 9:

  Write a Lex program which adds line numbers to the given file and display the same onto the standard output.

  View

• Practical 10:
