Euler Motors Embedded Design Engineer Interview Questions and Answers

Macro is a preprocessor directive that performs text replacement, while typedef creates an alias for data types.

• Macro is resolved by the preprocessor before compilation, while typedef is resolved by the compiler during compilation.

• Macros can be used for conditional compilation, while typedef is used to create new names for existing types.

• Example: #define PI 3.14159 for macro, typedef int integer for typedef.
