I have a question about the way you calculate the percentage, why we must take the totalT instead of total to calculate the CPU usage percentage?

Hello @Quang0309,

I just saw your issue now!

I don't know the logic behind that operation. But the way it's calculated is taken from this StackOverflow question: How to calculate the CPU usage of a process by PID in Linux from C?
