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 ...
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; ...
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
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
A type-insensitive macro is a macro that performs the same basic operation on different data types. This task can be accomplished by using the concatenation operator to create a call to a type-sensitive

Pointers to functions are interesting when you pass them to other functions. A function that takes function pointers says, in effect, “Part of what I do can be customized. Give me a pointer to a
