Program Explanation

In this C# program, we are reading the decimal number using ‘decimalnumber’ variable. Octal is a numbering system that uses eight digits, 0 to 7, arranged in a series of columns to represent all numerical quantities. Each column or place value has a weighted value of 1, 8, 64, 512, and so on ranging from right to left. Decimal is a term that describes the base-10. Using while loop checks the condition that the value of ‘quotient’ variable is not equal to 0. If the condition is true then execute the condition.

The octalnumber[] array variable is used to compute the modulus of the value of ‘quotient’ variable by 8. Compute the division of the value of ‘quotient’ variable by 8. For loop is used to print the octal number of the decimal value.

Runtime Test Cases
```
Enter a Decimal Number :
50
Equivalent Octal Number is 62```
