Question

I have to do a comparison and I want to know which will be faster.

1)

  for (i=0;i<4;i++){
     if (object1(i)==object2(i))
          retval = true;
     else { 
          retval = false;
          break;
     }
}

2)

 if ( (object1(0)==object2(0) && (object1(1)==object2(1) && (object1(2)==object2(2) && (object1(3)==object2(3)){
      retval = true;
 else
      retval = false;

Or both will perform the same?
Thanks for Advice

Answer 1

Strictly speaking the most efficient path would be:

retval = object1(0) == object2(0) && object1(1) == object2(1).....

This basically does the same as your loop, but doesn’t have to compare the result to true to determine the outcome of the condition.

However, I strongly recommend keeping the loop, as it is far easier to adapt to add or remove numbers.
