Simple loop, which one I would get more performance and which one is recommended? defining a variable inside a loop or outside of it?
- by Grego
Variable outside of the loop
int number = 0;
for(int i = 0; i < 10000; i++){
number = 3 * i;
printf("%d",number);
}
or Variable inside of the loop
for(int i = 0; i < 10000; i++){
int number = 3 * i;
printf("%d",number);
}
Which one is recommended and which one is better in performance?
Edit:
This is just an example to exhibit what I mean, All I wanna know is if defining a variable inside a loop and outside a loop means the same thing , or there's a difference.
