The first two lines of the program containing following statements
#include
#include
Those two lines looks like a program statements but they are not a part of function body, and doesn’t end with semicolon (;) .As program statements must instead of start with ash(#) and they are called Pre Processes Directories(PPD). While program statement give the instructions to the computers but the PPD gives the instruction to the compiler itself. The PPD #include tells the compiler to insert another text file in to your source file. The file name STDIO.H as an abbreviation for Standard Input output Header File. The Instruction #include tells the compiler to search for the file name stdio.h and place its contents at this point in the program .The symbol encode the header file name indicate that header file is located under user.
