![]() Related Questions A goto statement implements a local jump of program execution, and the longjmp() and setjmp() functions implement a nonlocal, or far, jump of program execution. Generally, a jump in execution of any kind Latest Answer : using the normal goto statement we can move only within the function. it is not possible to go from one function to another function.using setjmp and longjmp you can move from one function to another function. but it is very bad programming. since the ... Some operating systems (such as UNIX or Windows in enhanced mode) use virtual memory. Virtual memory is a technique for making a machine behave as if it had more memory than it really has, by using disk Latest Answer : Page size you have to choose as per the requirement. If you choose page size big then processing of page fault takes more time but if you choose page size small then there is possibility that more number of page fault occures but processing time of page ... The register modifier hints to the compiler that the variable will be heavily used and should be kept in the CPU’s registers, if possible, so that it can be accessed faster. There are several restrictions Latest Answer : If a variable is defined by using register modifier it tells to the compiler that the variable is used repetedly and that variable executes fastly. Generally register variables are defined in loop counters. This variable stored in CPU registers and access ... The volatile modifier is a directive to the compiler’s optimizer that operations involving this variable should not be optimized in certain ways. There are two special cases in which use of the A type cast should not be used to override a const or volatile declaration. Overriding these type modifiers can cause the program to fail to run correctly. A type cast should not be used to turn a pointer Latest Answer : we should not cast the big datatype to smaller one. Like from double to float long to integer. TIn these cases there will be chance of loosing the valuable data itself. ... A sorting program that sorts items that are on secondary storage (disk or tape) rather than primary storage (memory) is called an external sort. Exactly how to sort large data depends on what is meant Latest Answer : Any how after merging that it will create the same problem to sort out. Will you please explain about that? ... Most operating systems, including DOS, provide a means to redirect program input and output to and from different devices. This means that rather than your program output (stdout) going to the screen; Latest Answer : By using the operators "" we can redirect the standard input and out streams.example : d:> jinto.exe > outputredirected d:> ... The preceding example showed how you can redirect a standard stream from within your program. But what if later in your program you wanted to restore the standard stream to its original state? By using Tags : Restore Your C compiler library contains a low-level file function called sopen() that can be used to open a file in shared mode. Beginning with DOS 3.0, files could be opened in shared mode by loading a special By using the sopen() function you can open a file in shared mode and explicitly deny reading and writing permissions to any other program but yours. This task is accomplished by using the SH_DENYWR shared
