DECIMAL TO OCTAL CONVERSION IN C

 In this example, you will learn a program to convert decimal number to its equivalent octal number.

Decimal numbers have base 10 , and they use numbers between o to 9.

while, Octal  numbers have base 8 , and they use numbers between 0 to 7.

( To understand this program , you should have prior knowledge about decimal to octal conversion. )

Program:

//Program to convert decimal number to octal number

#include<stdio.h>
#include<conio.h>

int DectoOct( int num);
int main( )
{
int num;
printf("Enter a decimal number:");
scanf("%d",&num);
printf("%d decimal number= %d in octal number", num, DectoOct(num) );
return 0;
}

int DectoOct(int num)
{
int OctalNumber=0, i=1;

while(num !=0)
{
OctalNumber += (num %8)*i;
num /= 8;
i*=10;
}

return OctalNumber;
}

Output:

Enter a decimal number: 10

10 decimal number= 12 in octal number
