Understanding Number Systems in C++

Can you explain the different number systems used in C++?

Sure! In C++, we primarily use decimal, binary, octal, and hexadecimal number systems. Each has its own base.

What is the base of the binary number system?

The binary number system has a base of 2, which means it uses only two digits: 0 and 1.

How do I convert a decimal number to binary in C++?

You can use bitwise operations or a loop to divide the number by 2 and store the remainders. Would you like a code example?

Yes, please provide a code example for that.

Here's a simple code snippet to convert decimal to binary:

#include <iostream>
using namespace std;

void decimalToBinary(int n) {
    if (n > 1)
        decimalToBinary(n / 2);
    cout << n % 2;
}

int main() {
    int num = 10;
    decimalToBinary(num);
    return 0;
}

This will output the binary representation of the number.
