I want to call my function with string parameter

Question

void GenerateDecryptedData("/home/merve/merve.enc", "/home/merve/merve.dec","dEneMe!1234");

I want to call my function like dEneMe!1234.

void GenerateDecryptedData(const char* pathToEncryptedFile, 
                        const char* pathToDeccryptedFile,
                        std::string Pwd);

But when I wrote the function prototype like this, I'm taking string has not been declared- error! How can I take my password in string type?

By the way it's better to change the first two parameters to `std::string` too — NetVipeC, Sep 11 '14 at 16:31

But those are not string values, those are just file paths @NetVipeC — someWhereElse, Sep 11 '14 at 16:50
And what benefice do you gain from `char*` and not from `std::string` for file paths? — NetVipeC, Sep 11 '14 at 17:23

You need the string header at the top of your source file: #include <string>. I'd consider Googling error messages more often. :)

string header - http://www.cplusplus.com/reference/string/
cstring header - http://www.cplusplus.com/reference/cstring/

What's wrong with:

void GenerateDecryptedData(const char* pathToEncryptedFile, const char* pathToDeccryptedFile, const char* Pwd);

I tried this one too but then it's saying something wrong with "dEneMe!1234" Why then I call this way? – someWhereElse Sep 11 '14 at 16:37
If you tried that, why didn't you say so? Post that you've tried it, and what happened when you did. – Gutblender Sep 11 '14 at 16:40

Oh my God! The answer writing the whole time. It's a function call not a function decleration. I'm very sorry. – someWhereElse Sep 11 '14 at 16:55
