[C++] '\0' & '\n'

With testing length of characters, I discovered very harm misunderstanding.

I usually wrote '\n' to mean 'NULL', but it's terribly wrong.

Here is my source code.

* Code *

#include <iostream>

#include <string.h>

#include <locale.h>

int main()

{

char* Str1 = "Count." ;

char* Str2 = "Count.\0" ;

char* Str3 = "Count.\n" ;

wchar_t* wStr1 = L"Count." ;

wchar_t* wStr2 = L"Count.\0" ;

wchar_t* wStr3 = L"Count.\n" ;

std::cout << "Length of " << Str1 << " =" << strlen(Str1) << std::endl ;

std::cout << "Length of " << Str2 << " =" << strlen(Str2) << std::endl ;

std::cout << "Length of " << Str3 << " =" << strlen(Str3) << std::endl ;

wprintf(L"Length of '%s' : %d\n", wStr1, wcslen(wStr1) );

wprintf(L"Length of '%s' : %d\n", wStr2, wcslen(wStr2) );

wprintf(L"Length of '%s' : %d\n", wStr3, wcslen(wStr3) );

// to stop to destroy

int i ;

std::cin >>  i ;

return 0 ;

}

If you are a student who studies C++, let you guess the result.

Here is the result.

* Result

I have known '\n' means 'NULL', but it didn't.

'\n' means 'ENTER'.!!

'\0' means 'NULL'.
