malloc and tcache Demo

This is a simple C program to demonstrate dynamic memory allocation and tcache behavior in glibc.

Features

• Allocates and frees memory using malloc and free.
• Shows how freed chunks are reused by tcache for faster allocation.
• Demonstrates multiple allocations and reuses of memory blocks of different sizes.

How to Run

gcc -g heap.c -o h
./h

gdb ./h
break main
run
heap arenas
heap chunks
heap bins
