Clearing out arrays

I need to clear 2 arrays before i execute a function a 2nd time.

They are initially setup globally as :-

NSString *allAnswers[10];
int used[6];

What would be needed to clear/reset these before running the function again?

Thanks.

You can loop through those items, resetting their values to whatever you want.

for (NSInteger i = 0; i < 10; i++)
    allAnswers[i] = nil;

for (NSInteger i = 0; i < 6; i++)
    used[i] = 0;

If using Objective-C, you might want to consider using NSMutableArray in the future rather than C-language arrays like these.

memset(allAnswers, 0, sizeof(NSString*)*10);//This statement to clear array of NSString pointers
memset(used, 0, sizeof(int)*6);//This statement to clear array of integers.

Alternatively you can run loop to clear each element individually.

Use a loop to clear your arrays by 0 or whatever value you want. 

for(int i = 0; i < 10; i++)
{
     if(i < 6)  
         used[i] = 0;
     allAnswer[i] = 0;  
}
