OUTPUT:

DESCRIPTION:

In this variable we ask the user to input a number and we take out the each digit of number and cube it and is stored in a variable. In this way,we finally compare the value of num and sum then we display the result.

USED VARIABLE:

1.sum=it is used to store the value of the sum of cube of each digit.

2.i=it is used to store the last digit of the number.

3.temp=it is used to store the value for future need.

4.num=used to store the user input value.
