 Related Questions A switch statement is generally best to use when you have more than two conditional expressions based on a single variable of numeric type. Latest Answer : Also, a modern C optimizing compiler will generate the same binary for multiple "if" statements as opposed to a "switch" statement. However, code that uses "switch" for multiple numeric (symbolically speaking) comparisons ... 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 Floating-point numbers are the “black art” of computer programming. One reason why this is so is that there is no optimal way to represent an arbitrary number. The Institute of Electrical Latest Answer : A program running in the database that can take complex actions based on the inputs you send it. Using a stored procedure is faster than doing the same work on a client, because the program runs right inside the database server. ... For integral types, on a machine that uses two’s complement arithmetic (which is just about any machine you’re likely to use), a signed type can hold numbers from –2(number of bits – Latest Answer : Consider the 3 bitsFor signed int these 3 bits contains both positive and negative valuesyou can find max and min values as follows-2 ^ ( n-1 ) to ( 2 ^ ( n-1 ) - 1 ) ie, n is no. of bits-4, -3, -2, -1, 0, 1, 2, 3For unsigned int you can find the ... 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 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
