Can't convert to upper case (string)

[conan9]

Hi folks,,

I'm new here and having trouble to compile uppercase ....

and here is my code:

#include <iostream>
#include <string>
#include <iomanip>
#include <algorithm>
 
using std::cout;
using std::cin;
using std::endl;
using std::string;
using std::getline;
using std::fixed;
using std::setprecision;
using std::transform;
using namespace std;
 
 
 
int main()
{
    //declaring a variable
    string state="";
 
    //getting the input
    cout<<"Enter the State : "<<endl;
    cin>>state;
 
 
    //states=toupper(states);
    transform(state.begin(), state.end(), state.begin(), toupper);
 
    //determain the state that the user input
    if (state=="HAWAII")
    {
        cout<<"The shipping charge for Hawaii is $30.00. "<<endl;
    }//end if
    else if (state=="OREGON")
    {
        cout<<"The shipping charge for Oregon is $30.00."<<endl;
    }//end else if
    else
    {//end else
        cout<<"Incorrect State..";
    }
 
return 0;
}
 

and this is the error knowing that I have Mingw as a compiler:

 ----jGRASP exec: g++ -g C:\Users\Conan9\Desktop\ChargeStates.cpp
 
C:\Users\ayman\Desktop\ChargeStates.cpp: In function `int main()':

 ----jGRASP wedge2: exit code for process is 1.

Please Help!!

What is toupper in the last line? It's not a function - you don't pass it anything or save the return value. It's not a variable, you haven't declared it... The line above it looks more correct than the last line...

Your code works fine using Visual Studio.NET 2005. Hawaii gets converted to HAWAII just as you wish.

To Sicarie:

toupper is the address of the toupper(). The transform algorithm will call toupper() using each element of the container, in this case a char.

You are supposed to do this rather than code your own loop.

Thank you all,

However why is it not working when using Jgrasp??

You might try including <functional>. That's supposed to be included by <algorithm> but one never knows.

Wow, I've never seen that. Thanks for the clarification.
