Compiler design solved examples

How do you solve first and follow in compiler design?

Rules to find First()
If X is a terminal, then First(X) is {X}.
If X is a non-terminal and X tends to aα is production, then add 'a' to the first of X. if X-\x26gt;ε, then add null to the First(X).
If X_\x26gt;YZ then if First(Y)=ε, then First(X) = { First(Y)-ε} U First(Z)..

Types of parsing

The 6 phases of a compiler are:

What are compilers with examples?

A compiler is a special program that translates a programming language's source code into machine code, bytecode or another programming language.
The source code is typically written in a high-level, human-readable language such as Java or C++..

What is an example of a compiler working?

Now, here you will see how you can execute the compiler phase at each level and how it works.
