In Computer Science, generally Octal number system used to store big data values. We know that computer only understands binary numbers that are 0 and 1. Every data are given as input to computer converts into binary number system. Here we will write a C program to convert octal to the binary number system. So, we will use pow function defined under standard library function math. First Octal will be converted to Decimal and after that conversion will be done from Decimal to Binary.
The first program is created that actually converts and then prints binary equivalent of given octal number. And the second program just prints the binary equivalent of each and every octal digit one by one. Before going through these programs, if you're not aware about the simple steps and formula used for the conversion, then you can refer to octal to binary formula to get every required things.
Given an Octal number as input, the task is to convert that number to Binary number. Octal Number : An Octal number is a positional numeral system with a radix, or base, of 8 and uses eight distinct symbols. Binary Number : A Binary number is a number expressed in the base-2 binary numeral system, which uses only two symbols: which are 0 zero and 1 one. To convert an Octal number to Binary, the binary equivalent of each digit of the octal number is evaluated and combined at the end to get the equivalent binary number.
