In C Language we can use the malloc, calloc & ralloc for memory handling but if we use the above function we should free the memory when the memory is not required.It can be done by "free" function. And also one important point is, suppose if we allocate a memory for an structure and in the process time if the structure is not required the it should be removed by using the "free" function because the system or process will be get crashed on some situations.
