Changing array inside function in C

Question

I am learning C and confused why a array created in the main wont change inside the function, i am assuming the array passed is a pointer, and changing the pointer should\'v

Answer 1

You pass a pointer to the array array to the function change. In this function you create another array called new (using new as a name is a bad idea) and then assign it to the locally created function parameter array. You do not modify pointer in your main function. If you would like to do so, you should use

array = change(array,length);

in your main function and

int *change(int *array, int length) {
    int *variable_called_new =(int *)malloc(length*sizeof(int));
    [...]
    return variable_called_new
}

in your change function.
