1. What is a ‘pass’ in a compiler? Differentiate between a multiple pass compiler and a single pass compiler.

2. Describe the common data structures used by a compiler.

3. Write a simple ‘C’ language ‘Hello World’ program and compile it with the ‘gcc’ compiler to generate an executable program. Invoke the ‘gcc’ compiler in verbose mode (–v) to identify all the utilities that are used during the compilation process.
