First locate the position of an array by search after than use a delete function to delete an array
If you are referring to the character object 'char,' then here are a couple of uses:To create an object, use this:char object = 'a';To create an array of chars, use this:char array[10];To dynamically allocate an array of chars, use this:char array = new char[10];(Don't forget to delete the object with 'delete [] array')
The only way to delete objects in an object oriented programming language (unless they were created in heap memory) is for the object to go out of scope. If the object is declared in the heap, in c++ you would use delete[] ptr; or delete ptr; where ptr is a pointer to your object.
C compiler delete only those memory which is dynamically created. So we can't delete the value of array.
You use delete object in C++ to delete an object. You can also implicitly delete the object, if it is automatic type, by going out of local scope.
You cannot delete elements from an array. But you can move the elements: if (del_index < no_of_elements-1) { memmove (&array [del_index], &array [del_index+1], sizeof (array [0]) * (no_of_elements - del_index - 1)); } --no_of_elements;
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)
In C++ you would pass a std::array if the array is fixed-length, otherwise you'd use a std::vector. Most object oriented languages will provide some method of passing a self-contained array object to a function. In C and other non-object oriented languages you would pass a reference or pointer to the start address of the array along with a variable indicating the number of valid elements within the array. The array type will determine the size of each element.
A std::string is an object that encapsulates an array of type char whereas a C-style string is a primitive array with no members. A std::string is guaranteed to be null-terminated but a C-style string is not.
#include<iostream> struct object { int m_data; }; void main() { object obj=new object; obj.m_data = 42; delete( obj ); return( 0 ); }
Any name can be placed in an array, be it a primitive name or an object name, even a function pointer. Four examples of common objects that may be placed in an array include any object defined in the STL (standard template library), which includes vectors, lists, iterators and maps. All are self-explanatory, although a vector is simply an array implemented as an object. Therefore an array of vectors is nothing more than an array of arrays (effectively a multi-dimensional array). However, vectors are the "correct" way of implementing arrays in C++ (unless you specifically wish to use C-style code in your C++ projects), thus a multi-dimensional array is best implemented as a vector of vectors.
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.
