C - Data Type Octal Constants

Introduction

An octal value is a number to base 8.

Each octal digit has a value from 0 to 7, which corresponds to three bits in binary.

An integer constant that starts with a zero, such as 014, will be interpreted as an octal number.

014 is the octal equivalent of the decimal value 12.

#include <stdio.h>

int main(void)
{

    printf("%d.", -14);
    return 0;//from  w  w w. j a  va2  s . co m
}
