Kindly give Effective Answer to Measure Efficiency

[norman]

Hi All,
I have with me several C program collections. In this collection I have more than one program to achieve the same purpose. That is for instance for doing sorting in of an array I have more than one way of doing this. Like this I have so many programs. I want to reorder this collection based on efficiency of each program. How do I measure efficiency of each program? What are all attributes I have to check to measure the efficiency?

Regards,
Norman

Hi,
One of the main attribute for measuring efficiency of any program would be to time taken to execute the program. But someone would have to clarify us how to measure the time taken for executing a C program

Hi, u'll always have to sacrifice one out of two important criteria to achieve better performance / efiiciency. "Memory space and running time". A program that optimally sacrifices these two for a given problem must be the most optimal one.

Blenda and Hrithick thanks for your brief explanation.If there are any other attributes we have to check to measure the efficiency mention it here in this discussion so that we can get a more detailed view in this related area.
