Why is count returning 0 for number of objects in my array when there should be 3?

Question

int main(int argc, const char * argv[]) { @autoreleasepool {

    NSMutableArray *myMute;
    NSString *stringOne = @"This is string 1";
    NSString *stringTwo = @"This is string 2";
    NSString *stringThree = @"This is string 3";

    [myMute addObject: stringOne];
    [myMute addObject: stringTwo];
    [myMute addObject: stringThree];

    NSLog(@"There are %li objects in the myMute array", [myMute count]);


    return 0;
}

}

Just allocate array you create nil array you have to allocate it memory with new or alloc

NSMutableArray *myMute = [NSMutableArray new];

    NSString *stringOne = @"This is string 1";
    NSString *stringTwo = @"This is string 2";
    NSString *stringThree = @"This is string 3";

    [myMute addObject: stringOne];
    [myMute addObject: stringTwo];
    [myMute addObject: stringThree];

    NSLog(@"There are %li objects in the myMute array", [myMute count]);


    return 0;
