C++ int type Octal Literals

Introduction

You can write integer literals as octal values with base 8.

You mark a number as octal by writing it with a leading zero.

Octal literals:	0657	0443U	012L	06255	0377
Decimal literals:	431	291U	10L	3245	255

#include <iostream>

int main()//w ww .  j av  a2s. c  om
{
    unsigned int a {0657};

    std::cout << "The value of a is "  << a  << std::endl;
}
