This program takes a octal number as input and converts it into binary.



This program takes a octal number as input and converts it into binary.

Take a octal number as input.
Print the binary value of each digit of a octal number. Use switch statement and while loop to do this.


    #include <stdio.h>

    #define MAX 1000
     

    int main()

    {

        char octalnumber[MAX];

        long i = 0;

     

        printf("Enter any octal number: ");

        scanf("%s", octalnumber);

        printf("Equivalent binary value: ");

        while (octalnumber[i])

        {

            switch (octalnumber[i])

            {

            case '0':

                printf("000"); break;

            case '1':

                printf("001"); break;

            case '2':

                printf("010"); break;

            case '3':

                printf("011"); break;

            case '4':

                printf("100"); break;

            case '5':

                printf("101"); break;

            case '6':

                printf("110"); break;

            case '7':

                printf("111"); break;

            default:

                printf("\n Invalid octal digit %c ", octalnumber[i]);

                return 0;

            }

            i++;

        }

        return 0;

    }

Take a octal number as input and store it in the array octalnumber.
Using switch statement access each digit of a octal number and print its equivalent binary value in a 3 bit fashion. For example: for 0, print its binary value as 000.
Do step 2 under a while loop.
Exit.
