    toupper, strcpy and strtok.

    Quzah.
    Hope is the first step on the road to disappointment.

    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';
    }

    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.

    >I couldn't find any toupper()/tolower() func
    Try <cctype> or <ctype.h>. If they're not there then your compiler has issues.
