Answer 1

C++

Explanation:

#include <$stdio.h$>

$int$ main()

{

$int$ m, n, count=0;$printf$("Enter any number: ");

$scanf$("%d", &m);

while(m>0)

{

n= num%10;

m=m/10;

if(n%2==0)

{

    count++;

}

 }

   $printf$("The frequency of even digits is %d ",count);

}

Note:

• n= num%10 is used to find out the last digit of entered number m and stored it in variable n.
• m= m/10 is used to remove the last digit of entered number m and update the value of m.
