The different functions that we used to allocate memory dynamically at run time are − malloc () − allocates a block of memory in bytes at runtime. calloc () − allocating continuous blocks of memory at run time. realloc () − used for reduce (or) extend the allocated memory. f...
Briefly explain the purpose of the loop, or iteration, structure. Then provide an original example algorithm with the loop structure. Why is a bitmap index used in data warehousing? How does cloud storage work? Do you always need to get the largest amount of RAM possible? Why or why not...
Beware of facile claims like "Unix writes are atomic"; the situation is a lot more nuanced than that. it can be verified that no locking is needed. As we saw in our example, storing a pointer to a mutex enables a logger and all of its clones to synchronize with each other. Beware ...

For example, the string constant “welcome \ “home” is displayed as welcome” home. Note that the double quote next to the backslash is an escape sequence and not a delimiter for the string constant. In Secondary these are 1) Array 2) Pointer 3) Struc...
example 2: Char *ptr = Hello; *ptr =h; / / error The first string is opened with an array, and it is a variable that can be changed. The second string is a constant, or literal value. The PTR simply points to its pointer and cannot change the contents of the pointer. See the ...

Pointer to output data I/O; PTR(SPP) A pointer to data that can be viewed as a set of records or multiple entries within an array. This data is used to determine the pictorial representation of the query. The user can retrieve the data in any manner. One suggested method is to view...
Hmm .. easy to do with a few fixed values, a little harder with a random number of items to search for. But thanks for the pointer Tim 13 Jun 12 at 15:26 Nice work but the picture titles and descriptions are really confusing. Other than that, a great photo blog. Andy 20 Aug 12...
