How to print a hexadecimal value in high box?

Question

I made a program in C++ that reads a number and prints it in hexadecimal, follows the code below.

#include <iostream>
using namespace std;

int main(void) {

    int n;  
    cin>>n; 
    cout<<hex<<n<<endl; 

    return 0;
}

Only he prints everything in minuscule and I’d like you to print it in maísculo, how can I do that?

Answer 1

It is only user the uppercase:

#include <iostream>
using namespace std;

int main(void) {
    int n;  
    cin >> n; 
    cout << uppercase << hex << n << endl; 
}

Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.
