C Program convert decimal to octal Number

 In this example,we will discuss about how to convert decimal to octal in the c programming language.Following is the solution of the problem.

code:

#include <stdio.h>

#include <math.h>

using namespace std;

int main()

{

   int deciNumber,originalnumber;

    printf("Enter a decimal number: ");

    scanf("%d", &deciNumber);

  originalnumber=deciNumber;

    int octalnumber = 0, i = 1, remainder;

    while (deciNumber != 0) 

    {

           remainder = deciNumber % 8;

        deciNumber /= 8;

        octalnumber += remainder * i;

        i *= 10;

    }

     printf("%d in decimal = %d in octal", originalnumber, octalnumber);

   return 0;

}

Output:

Enter a decimal number: 60

60 in decimal = 74 in octal
