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 : First of all there is a one sentence definition of Page Thrashing (I believe someone posted a similar answer here):Page Thrashing only comes about when you use Virtual Memory which requires an MMU and "fools" a process into believing that it ... 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 There are two situations in which to use a type cast. The first use is to change the type of an operand to an arithmetic operation so that the operation will be performed properly. The second case Latest Answer : Type cast should be used in case of if we want to assign a void pointer to a pointer of some data type.eg:void *ptr;int *c;c=(int *)ptr; ... 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 global variable that must be accessed from more than one file can and should be declared in a header file. In addition, such a variable must be defined in one source file. Variables should not be defined Latest Answer : A variable can be declare/define in a C Header without any kind of compilational/ logical errors.

A sorting program that sorts items that are on secondary storage (disk or tape) rather than primary storage (memory) is called an external sort.
