When I checked my application for memory leaks it is showing 12 leaks. What will be the effect of this?

I used global variables as shown below

#import "file1.m"

int num;

#import "file2.m"

extern int num;
num = 10;

Can this cause memory leaks?

Anyone please help. I am a beginner in programming.
