What is #include<stdio.h> ??

• Basically to expand (x+2)^2 we have a basic formula from our school text book
• Similarly to solve or to use many standard inbuilt functions  this #include<stdio.h> will helps us
• This #include<stdio.h> is called header file.
• Hence these header files can be treated as a textbook for compiler 
• for eg., printf(),scanf() functions were stored in this header file ,so compiler can understand how these functions works
• There are more than 10 header files in c each header file has it own libraries. 

****IN C++ we can use #include<bits/stdc++.h> which covers all funtions in it.*****
