Analyzer c-count-alloc-free

# Name

c-count-alloc-free - C Application-Level Memory API Calls

This analyzer tracks and counts memory allocation and deallocation API calls in C-based applications. It monitors calls to malloc, calloc, realloc, free, and related memory management functions. The analyzer provides statistics on allocation counts. This is valuable for identifying excessive memory operations, detecting potential memory leaks through imbalanced allocation/deallocation ratios, and understanding memory management behavior in C applications.
