use the backslash: "\"" is a string containing "
like this:
char str[67] = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'-_\"";
added one for the implicit '\0' at the end (and put in the missing vV) - this could also be:
char str[] = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'-_\"";

The difference between the two ways of creating strings, is that the first method is easier to write, and you do not have to include the \0 character, as C will do it for you.

Do I only use
#include <string>if a variable represents a string?
Yes.
Use #include <string> when you use a variable that has type std::string.
The code "text here", contrary to intuition, is not a std::string; it is a string literal, and a C-style string, and a const char[10] convertible to const char*. Welcome to C++ with its legacy oddities.

If you use the type std::string in your code then you should include the <string> header. There are also a few other types and functions in that header, but std::string is the most commonly used one.
However, you do not need to include this header just to use string literals, which are built into the core language.

printf and it's variants are among the most used and useful string functions that I use. If we're counting other functions in string.h I'd definitely add memset and memcpy.

noteworthy I'd say noteworthy doesn't necessarily equate to useful. I think it's better to know what not to use, and then pick from the rest as needed. strtok is a really bad API. If you need to tokenize a string, making your own function is pretty much always better than using strtok. ato* functions are essentially always worse than just using strto* variants. The strcpy and strcat families are finicky. Ideally you should just implement one of the popular variants, like strscpy, and use that. If you want to include IO functions as "string functions', then there's a couple obvious pitfalls. gets, while removed from the standard, is worth knowing about purely for how awful it was. scanf is not meant for arbitrary input; many books use it for brevity, but it's harder to use correctly compared to manually parsing a string from fgets.

Functions whose names begin with "mem" perform similar tasks but with more general data. The frequently used header files (e.g., <iostream>) provided with some compilers chain one header to another by including the C-string header file, making an explicit #include <cstring> unnecessary.

Im a beginner in cpp. I have experimented and realised that I can use std::string and std::getline without the need of <string>. The <iostream> seems to take care of it. Is there any real need to use <string>?

Yes, to use std::string you must include does not have to include any or all of the definition of std:: string

Includes can include other includes. In your case string is probably included by iostream, so you don't need to include string yourself. However, this is not the same with all compilers and different versions of the same compiler will sometimes change what is included by what. I wouldn't worry about it right now, just be aware than if you change compilers you might find that some includes are missing and will need to fix them. This situation will change if modules ever take off properly because a module doesn't need to export the things it itself depends on. So iostream might import string for its own purposes, but won't make it available to you.
