How is hexadecimal used in C++ programming?

Hexadecimal is often used in C++ for representing memory addresses, color codes, and binary data in a more readable format.

Can you give me an example of using hexadecimal in a C++ program?

Sure! Here's a simple example:

#include <iostream>
using namespace std;

int main() {
    int hexValue = 0x1A; // Hexadecimal representation of 26
    cout << "The decimal value is: " << hexValue << endl;
    return 0;
}

What are the advantages of using hexadecimal over decimal?

Hexadecimal is more compact and easier to read for large binary values, making it ideal for programming and debugging.

Are there any specific functions in C++ for converting between hexadecimal and decimal?

Yes, you can use std::stoi for converting a hexadecimal string to an integer, and std::hex to format output in hexadecimal.
