    string to upper

    I must be staring at this for too long because Ive been able to do this simple loop in the past...not today. Im just trying to take a string including spaces or characters and convert it to uppercase letters. Where am I going wrong please?

    Code:
         cout <<"\nPlease enter your full name: ";
         getline(cin,ch);
         cout << endl;
    
    
         for (int x = 0; x < ch.length(); x++) 
         {            //takes each character and converts it to uppercase letters
         cout << (char)(toupper(ch.at(x)));
         }

    For a string, use the transform function to uppercase all letters, including those separated by spaces:

    Code:
    #include<iostream>
    #include<conio.h>
    #include<algorithm>
    #include<string>
    using namespace std;
    
    void main()
    {
    string ch;
    cout<<"\nPlease enter your full name: ";
    getline(cin,ch);
    cout<<endl;
    transform(ch.begin(), ch.end(),ch.begin(), ::toupper) //replacement function
    cout<<ch;
    getch();
    }
