 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 : 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 Yes. The const modifier means that this code cannot change the value of the variable, but that does not mean that the value cannot be changed by means outside this code. For instance, in the example in Latest Answer : But isnt like the constant variables will be stored by in ROM (read only memory).Then how can the some process other than the code can change the value of const volatile ... 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. ... The answer depends on what you mean by quickest. For most sorting problems, it just doesn’t matter how quick the sort is because it is done infrequently or other operations take significantly more Latest Answer : The algorithms which follows divide and qunquer technique provides fastest implementation. ... 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? ... Just as qsort() was the easiest sorting method, because it is part of the standard library, bsearch() is the easiest searching method to use. If the given array is in the sorted order bsearch() is the A binary search, such as bsearch() performs, is much faster than a linear search. A hashing algorithm can provide even faster searching. One particularly interesting and fast method for searching is to Latest Answer : quick short method is a best one ...
