# Decimal to Octal Conversion

Decimal to Octal Conversion” is one of the classic programming problem exercise. Here, we are given a decimal number, entered by user and our task is to convert the given decimal number to its equivalent octal number.

Example (Decimal to Octal Conversion):

```88 -> 130
78 -> 116```

The steps for decimal to octal conversion are as follows:

1. Take Octal = 0, iterator = 1.
2. Store the remainder when the decimal number is divided by 8.
3. Divide the decimal number by 8.
4. Octal = Octal + iterator * remainder.
5. Multiply the iterator by 10.
6. Repeat the steps from 2 to 5 until decimal number is not 0.
7. Print the Octal Number.

#### C++ Program for Decimal to Octal Conversion is as follows:

```/* C++ Program for Decimal to Octal Conversion */
#include<bits/stdc++.h>
using namespace std;
int main()
{
/* Scan the Decimal Number */
int Decimal;
cout<<"Enter the Decimal Number: ";
cin>>Decimal;

/* Converting Decimal to Octal */
int Octal = 0;
int iterator = 1;
int temp = Decimal;
while(temp != 0)
{
int remainder = temp % 8;
temp = temp / 8;
Octal = Octal + remainder*iterator;
iterator = iterator * 10;
}

/*Printing the result */
cout<<"The Octal of "<<Decimal<<" is "<<Octal;
}
```
```OUTPUT:
Enter the Decimal Number: 78
The Octal of 78 is 116```
