Variable operator for comparison

[Guest_imported]

Alright, hopefully this will be easy. I'm creating an integer heap (for a priority queue). However, I do not know if it's a high-num high-pri or a low-num high-pri until the user tells me so. Is there a way to interpret a char variable as an operator? Say, for example, char top_op = '<'; is there some way I could test
if(heap_array[2*n+1] **some function of top_op** heap_array[2*n+2]) ?
Thanks for any help.

Hi

I personally would use a switch statement on the user input then perform the necessary operation.

switch(top_op)
{
case '<':
.
.
break;
.
.
}

I think this makes your code much more readable and you can also validate the user input alot easier (using default: in the switch statement).

I don't know anyway of implementing it in the way you mentioned.

Hope that helps
