+            ~~~~~~~~~~~~~~~

+
+            When the size of any number of call stack crosses the 
+            finite size of the allocated stack of the program, then
+            it leads to stack overflow.

+        *   Address Sanitizer: 
+            ~~~~~~~~~~~~~~~~~~ 
+
+            To know about potential memory leaks, we can enable stanitizer flag
+
+            Compiler flag:
+                -fsanitize=address
+
+
+        *   To detect memory leak, we can use valgrind.
+
+            Command:
+            $valgrind --leak-check=full ./<program>
+            
+            OR
+
+            $valgrind ./<program>
