C Programming

I believe you can attempt to allocate as much as you want, but if you try to take more physical memory than your machine has then malloc will instead return a null pointer

intersection of elements

A NULL in C is a pointer with 0 value, which cannot be a valid address.

A null in Oracle is the condition of not having a value, such as a field in a row being null, meaning that it does not have a value. This is not the same as zero - zero and null are two different things.

Note, however, that Oracle does not differentiate between a null and a zero length string. This was an error in non-ANSI implementation made many years ago, but it has persisted because fixing it would impact too much "running" code.

Selection sort has the following implementation:

// sort an array if integers of length size in ascending order using selection sort algorithm:

void selection_sort (int a[], unsigned size) {

unsigned i, max;

while (size > 1) {

max = 0;

for (i=1; i!=size; ++i) if (a[i] > a[max]) max = i;

swap (a[max], a[--size]);

}

}

A however statement is a statement that says for example, Cafeteria rules are stupid; however, they have been improving the way the cafeteria runs

# include <stdio.h> void quicksort(int a[],int st,int end); main() { int n,i,b[10],c[10]; printf("Enter the number of elements"); scanf("%d",&n); printf("Enter the elements 1 by 1 \n"); for(i=0;i<n;i++) { scanf("%d",&b[i]); c[i] = b[i]; } quicksort(b,0,n-1); printf("\tQUICK SORT\n"); printf("\t**********\n\n"); printf("\tNumbers \tSorted List\n"); printf("\t******** \t***********\n"); for(i=0;i<n;i++) printf("\t%d\t\t%d\n",c[i],b[i]); } void quicksort(int a[],int st,int end) { int elt,low,high; low = st; high = end; elt = a[st]; while (st < end) { while ((a[end] >= elt) && (st < end)) end--; if (st != end) { a[st] = a[end]; st++; } while ((a[st] <= elt) && (st < end)) st++; if (st != end) { a[end] = a [st]; end--; } } a[st] = elt; elt = st; st = low; end = high; if ( st < elt) quicksort(a,st,elt-1); if (end > elt) quicksort(a,elt+1,end); } Enter the number of elements6 Enter the elements 1 by 1 34 12 9 0 45 123 QUICK SORT ********** Numbers Sorted List ******** *********** 34 0 12 9 9 12 0 34 45 45 123 123

Parse trees (also known as Concrete Syntax Trees) contain every token of the input as a leaf, and the interior nodes are nonterminals in the grammar used to parse.

Abstract Syntax Trees omit much of the detail that would be present in a CST. There are still leaf nodes when the associated tokens are information-bearing (such as identifiers and literals), but, for example, keywords and punctuation are not present in an AST. The interior nodes represent language constructs as defined by the grammar. An AST for an "if" statement (for example) would consist of one node to represent the "if" construct, and two or three subtrees, one for the "if" condition and another one or two for the "the" and optional "else" parts. The CST for such a construct would also contain the "if"/"then"/"else" keywords, such that you could walk the tree to obtain the original token sequence.

A structure is not an array. Individual array elements are accessed through a number, called a "subscript". This subscript can be a constant, or a variable, or any expression that can be evaluated to give an integer.

256 different characters is not enough

Unicode enables the reliable store most of the world's characters in a (2 byte) fixed width mode with 65,564 characters.

In C++ EOF is a special function which will return nonzero when there is no more data to be read. In C++ nonzero means true, the alternative to nonzero is zero which means false.

a fixed loop is obviously a loop that is fixed ;D

Iterative deepening effectively performs a breadth-first search in a way that requires much less memory than breadth-first search does.

So before explaining the advantage of iterative deepening over depth-first, its important to understand the difference between breadth-first and depth-first search. Depth first explores down the tree first while breadth-first explores all nodes on the first level, then the second level, then the third level, and so on.

Breadth-first search is ideal in situations where the answer is near the top of the tree and Depth-first search works well when the goal node is near the bottom of the tree. Depth-first search has much lower memory requirements.

Iterative deepening works by running depth-first search repeatedly with a growing constraint on how deep to explore the tree. This gives you you a search that is effectively breadth-first with the low memory requirements of depth-first search.

Different applications call for different types of search, so there's not one that is always better than any other.

1. Use merge sort
2. Use tree sort

Sorry, but I cannot answer this without actually seeing the line in question.

Matrices itself is a combination of rows and columns.we can not use one-dimenssional array to save the values of matrices.instead we use the rectangular array which contains rows and columns.thats it.

The answer is in the question: use function free.

The term "magic" has its place in programming history, and generally referred to something that is either understood by those who are experts, or understood by no one, as to How It Works.

Magic numbers in C and other programming languages today have a number of meanings:

- a constant value used to identify a protocol or file formats (file signatures);

- unique identifiers unlikely to be mistaken to mean other things;

- values whose usages are unexplained.

Some interesting examples of magic numbers include:

- Java bytecode files start with 0xCAFEBABE, but compressed with "Pack200" the code becomes 0xCAFED00D (this is magical);

- image files start with unique identifiers like "GIF89a", "GIF87a", or begin and end with unique values;

- Mark Zbikowski designed the EXE file format, which starts with MZ (0x5A 0x4D), ensuring at least part of his name was burned into the annals of history;

- On older systems, newly allocated or freed memory was marked with the 32-bit hexadecimal value 0xDEADBEEF, and initializing memory came to be known in some circles as "deadbeefing the memory" or "the memory is deadbeef".
