Wipro Developer interview questions

What makes a macro faster than a function in the C programming language? Macros are sections of code in a programme that have been given a name. The compiler substitutes this name with the real piece of code whenever it encounters this name. To define a macro, use the '#define' directive. Macros can be defined either before or within the main method.
