toupper, strcpy and strtok.

std::string::find() would be functionally equivalent to strtok()
and the assignment operators, constructors of the std::string class take care of strcpy.

i'm not aware of any toupper() in the std::string type.

There is no toupper in the std::string type. You can use the toupper in cctype (ctype.h). In stead of a for loop you can use the transform function in algorithm:

Code:

#include <string>
#include <cctype>
#include <algorithm>
#include <iostream>

int main(void)
{
   std::string msg = "Hello world";
   std::transform(msg.begin(), msg.end(), msg.begin(), toupper);
   std::cout << msg << '\n';
}

if you use MSVC
CharUpper()

I couldn't find any toupper()/tolower() func so so I just wrote my own

works fine for me

Noobs dont often write their own functions. They dont know how

Besides, you learn a lot more that way too

I'm with you, face_master. I have more fun writing my own function anyway. I've done my own isdigit, atoi, and strlen functions. I don't really like using library functions because I don't know how those functions work. That's one thing I don't like about data encapsulation——being kept in the dark about how everything works.

That's the reason for encapsulation

. But you can find implementations of the standard C library if you expend a small amount of energy looking.

Try <cctype> or <ctype.h>. If they're not there then your compiler has issues.
