The header file which is added to the program that one has written is basically what 'include stdio.h.' means.

The header file which is added to the program that one has written is basically what 'include stdio.h.' means. Stdio.h is known to contain the input and output operations like "printf" or "scanf" etc. "h" extension means the header file. If you request to use a header file in the program by actually including it with the preprocessed C directive #include like you have seen the inclusion of stdio.h header file, which comes along with the compiler you are using. If the header file is equal to that of copying the header file, it is advised not to do it because it would be inevitable to get an error and it's, of course, a bad idea to copy the content of the header file into its designated source files, as in if at all one has multiple source files in a written program. In layman's terms, It's effortless .#include is what is known as a "preprocessor". As the name suggests, it is preprocessed before the code. These preprocessor statements are compiled before any other code in your script.Hope this helps read less

stdio.h is a header file which contains the declarations (not the definitions) of standard I/O functions like printf(), scanf(), etc.,. The header file just tells the compiler what types external functions and variables are, defines macros, types etc. Any functions and variables that get referenced in your source file will be linked in during the linker phase. If you include stdio.h and use printf in your program, the compiler adds printf as an "unresolved" symbol in the object file, and then the linker will try to find a function called printf either in the object files you explicitly link, or in the libraries it is configured to search. read less

stdio.h contains prototypes for standard input/output functions like scanf/printf. Without including this file, one will not be able to read input from keyboard or write output to screen.

"stdio" stands for standard input-output. Some of the most commonly used pre-written functions are getc(), putc(), gets(), puts(), scanf(), printf() and also their file IO counter parts such as fputs(), fgets(), fprintf(), fscanf(), etc., are packaged into stdio.h. This package also includes certain...

Some of the most commonly used pre-written functions are getc(), putc(), gets(), puts(), scanf(), printf() and also their file IO counter parts such as fputs(), fgets(), fprintf(), fscanf(), etc., are packaged into stdio.h. This package also includes certain special functions such as fflush() and file IO related functions such as fopen(), feof(), fclose(), ftell(), fseek(), fwrite(), fread(), etc. Most of the C programs include one or more of the above functions to achieve a given task. Hence, it has to be included as a header file. read less

Better way to understand any header file is to remove the header file and execute the program and then see what are the errors you are getting. read less
