Next Lesson: Building a Linked List

Sum and Average on the Heap

Medium

Read a count n between 1 and 1000, allocate an int array of exactly n elements with malloc, check the result against NULL (print "allocation failed" and return 1 if it is), read n values with guarded scanf, then print the sum and the average to two decimal places, casting before dividing. Free the block before returning: this exercise fails on a memory leak even when the output is byte-perfect, so every path that owns the block must release it.
