Nettet29. mai 2013 · int a1 [10]= {0,1,2,3,4,5,6,7,8,9}; a1 is an array, so when a goes out of scope memory is freed otherwise int *a2= {0,1,2,3,4,5,6,7,8,9} a2 is a pointer (and i think you can't initialize it like that), and even if you do a2 = a1 the memory is still 'owned' by a1. Nettet3. aug. 2024 · int arr[5] = {1, 2, 3, 4, 5}; This initializes an array of size 5, with the elements {1, 2, 3, 4, 5} in order. This means that arr [0] = 1, arr [1] = 2, and so on. We don’t need to initialize all the elements 0 to 4. We can even do only from indices 0 to 2. The following code is also valid: int arr[5] = {1, 2, 3};
