In C++, we can use Binary numbers, Octal numbers and Hexadecimal numbers as Integer literal.
For declaring an Binary Integer literal, the Binary digits are placed after 0b or 0B.
eg. <0b>101 i.e. Binary (101)= Decimal (5)
For declaring an Octal Integer literal, the Octal digits are placed after 0.
eg. <0>112 i.e. Octal(112)= Decimal (156)
For declaring a Hexadecimal Integer literal, the Hexadecimal digits are placed after 0x or 0X.
eg. <0x>12 i.e. Hexadecimal(12)= Decimal (18)
//Program to demonstrate use of Binary, Octal and Hexadecimal numbers as Integer literals
#include <iostream>
using namespace std;
int main()
{
int a = 0106; // Octal(106)= Decimal(70)
cout<< a << endl;
int b = 0x46; // Hexadecimal(46)=Decimal(70)
cout<< b << endl;
int c = 0B1000110; // Binary(1000110) = Decimal(70)
cout<< c;
return 0;
}
