******ful earth

Like the above use of memset, can we initial

Answer 1

Since nobody mentioned it...

Although you cannot initialize the integers with value 1 using memset, you can initialize them with value -1 and simply change your logic to work with negative values instead.

For example, to initialize the first 6 numbers of your array with -1, you would do

memset(arr,-1,6*(sizeof int));

Furthermore, if you only need to do this initialization once, you can actually declare the array to start with values 1 from compile time.

int arr[15] = {1,1,1,1,1,1};
