Answer 1

Answer:

#include<stdio.h>

int main(){

              int num, digit, rem; // Declaring variables.

              printf("  Enter a number: "); //Asking for input from user

              scanf("%d",&num); //Taking input from user

              printf("\n  The Even digits present in %d are \n",num);

              while(num>0) // Loop to check even digits

              {

              digit = num % 10; //It will give the last digit's value to "digit"

              num = num / 10; //It will truncate the last digit and hence, removing last digit

              rem = digit % 2; //it will give remainder after dividing by 2

              if(rem == 0) //it will check if the remainder is 0 OR the digit is perfectly divisible by 2 OR the digit is even.

              printf("\n  %d.",digit); // It will print the number stored in "digit"

              }

       return 0; // It will return a number because the main's return type is "int"

   }
