Question
sir, actually we learnt in c that #include refers to preprocessor directive actually what is the difference between a directive and a directory what do u meanby preprocessor what does it do actually

Answer
Directory is also called as folder. That is a placeholder for files.
Pre-processor directive comes into picture before compilation starts.
There is a tool called pre-processor and it checks all the pre-processor directives and processes it and gives it for compilation.
