How do I perform hexadecimal operations in C++?

In C++, you can perform hexadecimal operations using the 0x prefix for hexadecimal literals. For example, 0x1A + 0x2B.

Can you show me an example of adding two hexadecimal numbers?

Sure! Here's an example:

#include <iostream>
using namespace std;

int main() {
    int hex1 = 0x1A; // 26 in decimal
    int hex2 = 0x2B; // 43 in decimal
    int sum = hex1 + hex2;
    cout << "Sum: " << hex << sum << endl; // Output in hexadecimal
    return 0;
}

What about subtracting hexadecimal numbers?

You can subtract them similarly. For example:

int hex1 = 0x2B;
int hex2 = 0x1A;
int difference = hex1 - hex2;
cout << "Difference: " << hex << difference << endl;
