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 ...
An lvalue was defined as an expression to which a value can be assigned. Is an array an expression to which we can assign a value? The answer to this question is no, because an array is composed of several
Latest Answer : Array is not an lvalue..Eg.int arr[5] = {"1","2",.......};here arr[5] has memory address and now we are assinging values to this.if we write arr[5]; in any function then it will not show any error, mean array does required lvalue ...
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 is the standard library function qsort(). It’s the easiest sort by far for several reasons: It is already written. It is already debugged. It has been optimized as much as possible (usually).
Latest Answer : Greetings!can u plz explain me the sorting function with its implementation in a small program and send it to my e-mail Id : venki_m182003@yahoo.com ...
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? ...
To hash means to grind up, and that’s essentially what hashing is all about. The heart of a hashing algorithm is a hash function that takes your nice, neat data and grinds it into some random-looking
Latest Answer : hash is actually using a maping function to map the items to keys, if two different items map to one key, a collision solution is needed. ...
