1. C Programming Review

a) Write a code snippet to allocate a 100 element integer array on the heap and initialize all elements to 0. Do not use C++ language features that are not available in C. (Hint: use malloc.)

b) Declare a C style struct to represent a linked list.

c) Implement a C function that takes a string as an argument and finds the first period character ( . ) in the string. It may return either the index or address of the period character.
