  Which part of the above do you find difficult to understand? I think it is the part where it says -
  
  a= num%10;
  n= num/10;
  
  Am I right?
  
  First part of understanding the code would be to understand what the % operator does.

  Check this out simpler program:
  
  

  int num,sum=0;
  printf("Enter a number\n");
  scanf("%d",&num);
   
  while(num >0){
           
              sum=sum+num%10;
              num=num/10;
           
          }
   
  printf("The sum of the digits of %d is    %d\n",num,sum);

  It will return you sum of any digit number.
  % operator is also called as modulo, That means it will return the reminder of operation.
  ps: I wrote this program in java. I hope it good in syntax wise for C.

  It does not find sum of 5 numbers But it finds the sum of the digits of a five digit number

  it would be good if we use for loop in this program
