Explanation:.
1. The function printf is not defined in the program.
The header file stdio.h contains only the declaration or prototype of the functions like printf
Since the header file stdio.h is not included in the program then printf is not declared.
2. Stdio.h is the function that allows us to output to screen
stdio.h is a header file in C, it is the file which contains C declaration and Macro definition to be shared between several files. stdio.h means standard input/output function which contains printf(), scanf() functions.
It is the header file for standard input and output. This is useful for getting the input from the user(Keyboard) and output result text to the monitor(screen)
3. The code includes no header file and two preprocessor directives
There's no header file in the program
The two preprocessor directives in the program are #include and #define
4. argc is not a function; it is a variable of type integer.
