Write a program numbers. cpp that defines a function bool isDivisibleBy(int n, int d); If n is divisible by d, the function should return true, otherwise return false. For example: isDivisibleBy(100, 25)

Here is the function in Python:

def isDivisibleBy(n,d):

   if(n%d)==0:

       return True;

   else:

       return False;    

Explanation:

Lets see how this works. You can call this function in main program to check if this function isDivisibleBy() works properly.

if(isDivisibleBy(8,2)==True):

   print("It is divisible")

else:

   print(" It is not divisible")

Now the bool function isDivisibleBy() takes two arguments, n and d. bool function returns either true or false. If the number in n is divisible by d the function returns true otherwise it returns false. The number n is completely divisible by d when the remainder of this division is 0. So modulus operator is used to check if n is completely divisible by d.

In main program if condition is used which calls the isDivisibleBy() function and checks if the function returns true. The function is passed two values 8 and 2 where 8 is n and 2 is d. If this condition evaluates to true then the message displayed in output is: It is divisible. When the if condition evaluates to false the messages displayed in output is: It is not divisible.
