=>FILE HANDLING IN C:
1) STATIC MEMORY ALLOCATION
2) DYANAMIC MEMORY ALLOCATION
BRIF DISCUSS ABOUT POINTS:
> In SMA memory is assign to varible at the starting of the program while in DMA memory is allocated at
the running time of program.
>In SMA memory is fixed in case of DMA memory can be changed.
>In SMA inefficient use of memory while in case of DMA efficient use of memory.
>In DMA memory can be expanded or contracted.So this provide flexibility tn programmer.
=>DYNAMIC MEMORY ALLOCATION FUNCTION:
1) MALLOC( )
2) CALLOC( )
3) FREE( )
4) REALLOC( )
