C++ - Seeing Binary Hex Oct Decimal

Base

//To print 'hex' and 'oct' one can simply use std::cout
int a = 10;
std::cout<< hex << a;
std::cout<< oct << a;
std::cout<< dec << a;


//To see the binary  whats comes in handy is std::bitset
#include <iostream>
#include <bitset>

#define MAX_BIT 8

using namespace std;

int main()
{
    char a = 'a';
    std::bitset<MAX_BIT> x(a);
    std::cout<<x;
    return 0;
}
