Answer 1

#define _CRT_SECURE_NO_WARNINGS

#include <stdio.h>
#include <string.h>

/*
The _CRT_SECURE_NO_WARNINGS macro is a compiler flag used in Visual Studio 
to suppress warnings about deprecated and potentially insecure functions 
in the C runtime library (CRT). These warnings are typically generated 
using older CRT functions with more secure counterparts.

	char buffer[16] = "";
	
	strcpy(buffer, "C Programming");
	
	printf("%s\n", buffer);

	return 0;
