When i am dynamically allocating memory (heap) in a program, and in this case if i am not making an explicit deallocation call or free() call then when will this dynamicaaly allocated heap will get deallocated.Is it at the end of program or is it at the end of c session or is it when i shut down my system.
NOTE : [This question was asked by Leomachy]
i think you get solution by follow the following steps:
-->write some C, c++ any code which will alocate some memory.
-->note down the address where you are allocating the memory.
-->Now meanwhile write and open another C program, which will display the
content of memory that you are allocating previously.
-->for the first program ,,,end the session and check in the second C program.

--> same way quit from the application and check in the second C program
memory content.

The allocated memory will last till you process ends. But this is not a good practice, u shuld deallocate the memory what u allocate else it can cause memory leak and your system will crash
