A Jagged array is an array of arrays.
You can initialize a jagged array as −
int[][] scores = new int[2][]{new int[]{92,93,94},new int[]{85,66,87,88}};Where, scores is an array of two arrays of integers - scores[0] is an array of 3 integers and scores[1] is an array of 4 integers.
A bit array is a kind of array data structure that stores a sequence of bits or boolean values as an array. It is also called a bitset, bitmap or bitstring. A bit is the basic unit of data in computer science. The bit represents one of two possible values( 0 or 1, True or False, Yes or No) of a logical condition in the form of 0 and 1. An example of an eight-bit array is 10011100. A jagged array is a special kind of multidimensional array that stores a collection of arrays of variable sizes. Each row of the jagged array contains columns of different sizes. It is also called as a ragged array. This implies that you can create an array with each element serving as a pointer(reference or link) to another array of the same type. Consider an example of a 2D matrix of size 3 X 3. One can say that the rectangular collection of size 3 X 3 will have 3 rows and 3 columns, but this is not the case with jagged arrays. In the case of jagged arrays, the number of rows is fixed, but the number of columns may not be fixed. The differences between a bit array and a jagged array are as follows: Array Elements: The elements of a bit array are digits( only 0 and 1), whereas the elements of a jagged array are arrays of variable size. Example of a bit array: 11011100. Example of a jagged array: int jagged_arr[][] = new int[][]{ new int[] { 1, 5, 6, 4 }, new int[] { 2, 3}, new int[] { 9, 8, 7}, }; Dimensionality: A bit array is generally one-dimensional but can be represented as two dimensional bit array. On the other side, a jagged array is a multidimensional array. Size: The size of the bit array is fixed, whereas the column size of the jagged array may not be fixed. Complex: A bit array is a simple array data structure, whereas a jagged array is more complex than a bit array. Parallelism: Bit-level parallelism is possible in a bit array, whereas it is not possible in a jagged array. The bit-level parallelism enables long-term storage and manipulation of small arrays of bits in the register set. It also maximises the use of cache data. Speed: Jagged array is faster than a bit array since the traversal is faster in jagged arrays than in single or multi-dimensional arrays. Compactness: The bit arrays have a variety of uses in areas where the efficiency of the system or required space is at a premium due to their compact design. On the other side, the design of jagged arrays is not compact, but they have a flexible design. Uses: One can use the bit arrays for priority queues and boolean flags. A bloom filter is a hash-based probabilistic data structure to determine if a given element is a component of a set. A jagged array is mainly used for memory management and faster code execution.
The lowest subscript of an array in C, or C++ is 0.
#include main() { int array[100], minimum, size, c, location = 1; printf("Enter the number of elements in array\n"); scanf("%d",&size); printf("Enter %d integers\n", size); for ( c = 0 ; c < size ; c++ ) scanf("%d", &array[c]); minimum = array[0]; for ( c = 1 ; c < size ; c++ ) { if ( array[c] < minimum ) { minimum = array[c]; location = c+1; } } printf("Minimum element is present at location number %d and it's value is %d.\n", location, minimum); return 0; }
Wright a 'C' program for storage representation of 2-D array.
Option 1) Use a temporary variable: int x = array[i]; array[i] = array[i+1]; array[i+1] = x; Option 2) Use bit operators: array[i] ^= array[i+1] ^= array[i];

A two-dimensional array is the simplest multi-dimensional array and is implemented as a one-dimensional array where every element is itself a one-dimensional array. We can imagine a two-dimensional array as being a table of rows and columns where every row is an array in its own right. A three-dimensional array is simply a one-dimensional array of two-dimensional arrays, which can be imagined as being an array of tables. Extending the concept, a four-dimensional array is a table of tables. Multi-dimensional arrays may be jagged. That is, a two-dimensional array may have rows of unequal length. Unlike regular arrays, jagged arrays cannot be allocated in contiguous memory. Instead, we use the outer array (the first dimension) to store pointers to the inner arrays. An array of strings (character arrays) is an example of a two-dimensional jagged array.
A string in C is stored in a 1 dimension array so an array of strings is simply a two dimension array.
The lowest subscript of an array in C, or C++ is 0.
Heres something i whipped up in a hurry... This uses the Bubble Sort method found (related links) #include <iostream> using namespace std; int main(int argc, const char* argv) { int arraysize = 5; //Unsorted array size int array [] = { 5, 3, 4, 2, 1 }; //The array of numbers itself //Display the unsorted array cout << "Before: {"; for (int c=0; c <= arraysize; c++) { cout << array[c]; if (c != arraysize) { cout << ","; } } cout << "}" << endl; //Acctually sort the array int tmp=0; //Used for swaping values for (int loop=0; loop <= (arraysize - 1); loop++) { for (int c=0; c <= (arraysize - 1); c++) //The sort loop { if (array[c] > array[c + 1]) { //Swaps the two values in the array tmp = array[c]; array[c] = array[c + 1]; array[c + 1] = tmp; //Cleanup tmp = 0; } } } //Display the sorted array cout << "After: {"; for (int c=0; c <= arraysize; c++) { cout << array[c]; if (c != arraysize) { cout << ","; } } cout << "}" << endl; return 0; }
You cannot add elements to a fixed array in C or C++. If, however, the array is declared as a pointer to an array, you can add elements by allocating a new array, copying/adding elements as needed, reassigning the new array to the pointer, and deallocating the original array.
The syntax to access a particular element in an array are the same in both languages: For example: assume array is an array of 10 int(egers): to get the first element: array[0] (both are 0 based indexing] int i = 0; while (i < array.Length) { // do something to array[i] } int i = 0; int length = sizeof(array) / sizeof(int); while (i < length) { // do something to array[i] } However, an array in C# is also enumerable (C does not have this feature) in C#, you may loop thru the array by: foreach (int number in array) { // do something to array[i] } Plus, C# is an Object-Oriented Language, so that an array may be of some object types, not just those primitiives data types in C: object[] objectArray; // any object derived from Object may be placed into objectArray, not just struct. In another variation, an array may be of Delegate type in C#(sort of like function pointers in C)
If the array consists of r rows and c column, and the total number of cells in the array are n = r*c, then r*c = n and c*r = n so that r*c = c*r : which is commutativity of multiplication.
#include main() { int array[100], minimum, size, c, location = 1; printf("Enter the number of elements in array\n"); scanf("%d",&size); printf("Enter %d integers\n", size); for ( c = 0 ; c < size ; c++ ) scanf("%d", &array[c]); minimum = array[0]; for ( c = 1 ; c < size ; c++ ) { if ( array[c] < minimum ) { minimum = array[c]; location = c+1; } } printf("Minimum element is present at location number %d and it's value is %d.\n", location, minimum); return 0; }

To get the size of an array in C, you can use the sizeof() operator. This operator returns the number of bytes occupied by the array, so to get the number of elements in the array, you can divide the total size by the size of one element.
