You should also include qustions that are in your paper thank
Important Qustions for ICS II
Q1: Write “C” code for sorting the data in my_list using Bucket sort algorithm and printing it in the same function. Use the following struct definition and prototype of the function (the function will be called as bucket_sort(&my_list))
typedef struct LIST_TYPE
{ int info[MAX];
int current_sixe; };
void bucket_sort(LIST_TYPE *list);
Note: MAX is a predefined constant integer and my_list.current_size = 1000)
