| With the help of dynamic memory we can determine memory required by variable during run time. |
| We find two type memory allocation static memory allocation and dynamic memory allocation. |
| In static memory allocation there is wastage of memory, but with the help of dynamic memory allocation we can save the amount of memory. |
| we need a variable amount of memory that can only be determined during run time ? For illustration, in the case that we need some user input to decide the essential quantity of memory space. |
| . Dynamic memory allocation means memory allocation at run time. |
