 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 ... 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; ... Declaring a variable means describing its type to the compiler but not allocating any space for it. Defining a variable means declaring it and also allocating space to hold the variable.

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 Streams can be classified into two types: text streams and binary streams. Text streams are interpreted, with a maximum length of 255 characters. With text streams, carriage return/line feed combinations Latest Answer : Will you please explain how binary mode takes less memory? ... Stream functions such as fread() and fwrite() are buffered and are more efficient when reading and writing text or binary data to files. You generally gain better performance by using stream functions The answer depends on the situation you are writing code for. Macros have the distinct advantage of being more efficient (and faster) than functions, because their corresponding code is inserted directly When writing your C program, you can include files in two ways. The first way is to surround the file you want to include with the angled brackets < and >. This method of inclusion tells the preprocessor Latest Answer : if you used #include" filename.h" for including header files then the compiler will check only in the current directory.but if you used #include for including header files then the compiler will checks all directories specified ...
