It is a programming language with strong abstraction from the details of the computer.

A cursor is a moving space, line, arrow, or hand that indicates the position of a text point or GUI location on a computer monitor. Actions taken with the mouse or keyboard will be implemented at the current cursor location.

Some sort of structure that lets you store a list of pending jobs - for example, an array, but it would have to be a resizable array. Some type of collection might be more appropriate. As you process one level of recursion, you add the "children" (which have yet to be processed) to the collection of pending jobs; once the "parent" is done processing, you remove it from the collection.

We don't avoid loops in programming. Loops are a fundamental feature of many algorithms. If we need to iterate over a data sequence in order to perform the same set of operations upon each data element, we would use an iterative loop. If we need to repeatedly reduce a larger problem into one or more smaller instances of the same problem until the problem is small enough to be solved we'd use a recursive loop.

Sample code is as follows:

#include <stdio.h>

void main()

{

int i = 0;

int final_number = 0;

int array[] = {1,2,3,4,5};

for(i = 0; i < (sizeof(array)/sizeof(array[0])); i++)

{

final_number += array[i];

}

printf("Sum = %d and average = %d", final_number, (final_number / i));

}

int main()

{

std::string first, last;

std::cout << "Enter your first name: ";

std::cin >> first;

std::cout << "Enter your last name: ";

std::cin >> last;

}

Storage classes are used to indicate duration and scope of a variable or identifier. Duration indicates the life span of a variable. Scope indicates the visibility of the variable. The static storage class is used to declare an identifier that is a local variable either to a function or a file and that exists and retains its value after control passes from where it was declared. This storage class has a duration that is permanent. A variable declared of this class retains its value from one call of the function to the next. The scope is local. A variable is known only by the function it is declared within or if declared globally in a file, it is known or seen only by the functions within that file. This storage class guarantees that declaration of the variable also initializes the variable to zero or all bits off. The extern storage class is used to declare a global variable that will be known to the functions in a file and capable of being known to all functions in a program. This storage class has a duration that is permanent. Any variable of this class retains its value until changed by another assignment. The scope is global. A variable can be known or seen by all functions within a program.

The queue insert operation is known is enqueue.

A queue has two ends namely REAR & FRONT. After the data has been inserted in a queue ,the new element becomes REAR.The queue deletion operation is known as dequeue.

The data at the front of the queue is removed .

float *pointer;

All data types can be used to store a whole number, even the data types that can store a decimal number.

Mathematically-speaking there is only one combination of a 3-digit number. When dealing with a combination of digits, the order of those digits does not matter, thus 123 and 321 are the exact same combination. If the order of the digits is important then it is a permutation, not a combination. That is, 123 and 321 are completely different permutations of the same combination of digits.

The confusion is understandable given that we commonly refer to a combination lock instead of a permutation lock. Mathematically speaking, a combination lock that unlocks with the code 123 would also unlock with the codes 132, 213, 231, 312 and 321, because all six permutations of the digits 1, 2 and 3 are in fact the same combination. Some combination locks really do work this way, however the vast majority are actually permutation locks; we call them combination locks simply because we don't normally use the term "combination" in the much stricter mathematical sense.

To restate the question: How do you write a C program to print all permutations of a 3-digit number?

A 3-digit number has 6 permutations, thus we can print all six by treating the number as an array, and printing all 6 permutations of the array:

void print_permutations (int num) { char set[3];

int index;

if (num<100 num > 999) return; // not a 3-digit number

index = 0;

while (num>0) {

set[index] = num % 10; // least-significant digit

num /= 10; // shift all digits one position to the right

}

// sort the array in ascending order

if (set[0]>set[1]) set[0]^=set[1]^=set[0]^=set[1];

if (set[1]>set[2]) set[1]^=set[2]^=set[1]^=set[2];

if (set[0]>set[1]) set[0]^=set[1]^=set[0]^=set[1];

// print the permutations

printf ("%d%d%d\n", set[0], set[1], set[2]); printf ("%d%d%d\n", set[0], set[2], set[1]); printf ("%d%d%d\n", set[1], set[0], set[2]);

printf ("%d%d%d\n", set[1], set[2], set[0]);

printf ("%d%d%d\n", set[2], set[0], set[1]);

printf ("%d%d%d\n", set[2], set[1], set[0]);

}

The problem with this is when the 3-digit number contains duplicate digits. This would treat 100 as if it had 6 permutations when it really only has 3 {100, 010 and 001}, while 111 only has one permutation {111}. These must be treated as being special cases:

void print_permutations (int num) {

char set[3];

int index;

if (num<100 num > 999) return; // not a 3-digit number

index = 0;

while (num>0) {

set[index] = num % 10; // least-significant digit

num /= 10; // shift all digits one position to the right

}

// sort the array in ascending order

if (set[0]>set[1]) set[0]^=set[1]^=set[0]^=set[1]; // move larger of 1st and 2nd digit to middle

if (set[1]>set[2]) set[1]^=set[2]^=set[1]^=set[2]; // move larger of 2nd and 3rd digit to end

if (set[0]>set[1]) set[0]^=set[1]^=set[0]^=set[1]; // move larger of 1st and 2nd digit to middle

// print the permutations (handle special cases where digits are duplicated)

if (set[0]==set[1] && set[0]==set[2]]) { // same three digits (one permutation)

printf ("%d%d%d\n", set[0], set[1], set[2]);

} else if (set[0]==set[1]) { // first two digits are the same (three permutations)

printf ("%d%d%d\n", set[0], set[1], set[2]); // same as 1, 0, 2

printf ("%d%d%d\n", set[0], set[2], set[1]); // same as 1, 2, 0

printf ("%d%d%d\n", set[2], set[0], set[1]); // same as 2, 1, 0

} else if (set[1]==set[2]) { // last two digits are the same (three permutations)

printf ("%d%d%d\n", set[0], set[1], set[2]); // same as 0, 2, 1

printf ("%d%d%d\n", set[1], set[0], set[2]); // same as 2, 0, 1

printf ("%d%d%d\n", set[2], set[1], set[0]); // same as 1, 2, 0

} else { // all three digits are unique (6 permutations)

printf ("%d%d%d\n", set[0], set[1], set[2]);

printf ("%d%d%d\n", set[0], set[2], set[1]);

printf ("%d%d%d\n", set[1], set[0], set[2]);

printf ("%d%d%d\n", set[1], set[2], set[0]);

printf ("%d%d%d\n", set[2], set[0], set[1]);

printf ("%d%d%d\n", set[2], set[1], set[0]);

The node is the part of the stem of the plant from which leaves, branches, and aerial roots emerge.

There are many nodes on a plant stem. The distance between each node is called the inter node.

Quick sort is not stable, but stable versions do exist. This comes at a cost in performance, however.

A stable sort maintains the order of equal elements. That is, equal elements remain in the same order they were input. An unstable sort may change the order. In some cases, the order of equal elements is of no consequence, but when two elements with different values have the same sort key, then order can be important.

types of sorting in c language are:

insertion sort

selection sort

bubble sort

merge sort

two way merge sort

heap sort

quick sort
