Return array in Objective-C

In Objective-C, you can return an array in two ways:

1. Using C Array - You can create a C array and return it from a method. Here is an example:

#import 

int *createArray(int count) {

    int *arr = malloc(sizeof(int) * count);

    for (int i = 0; i < count; i++) {

        arr[i] = i;

    }

    return arr;

}
int main() {

    int *arr = createArray(5);

    for (int i = 0; i < 5; i++) {

        NSLog(@"%d", arr[i]);

    }

    free(arr);

    return 0;

}

2. Using NSArray Class - You can use the NSArray class to create an array and return it from a method. Here is an example:

#import 

NSArray* getArray() {

    NSArray *array = @[ @1, @2, @3 ];

    return array;

}
int main() {

    NSArray *arr = getArray();

    NSLog(@"%@", arr);

    return 0;

}
