An array of pointers to string would contain, per array position, a number dictating which memory address holds the string data.
For example, position [0] in an array would contain a memory address. This memory address can be de-referenced to obtain the actual information held within that memory address.

What is an array pointers?
I guess it is an 'array of pointers'. Example:int main (int argc, char *argv[])
How do you store a string of letters for example abcdeabcde each to an array?
In C programming you would use the following: char a[] = "abcdeabcde"; If you wish to create an array with more than one string, use an array of character pointers instead: char* a[] = {"abcde", "fgh", "ijklm", "nopq", "rstu", "vwxyz"};
How do you use bsearch function to search a name sorted in array of pointers to string?

How do you use string in bubble sort in c plus plus code?
Do you mean how do you sort strings using bubble sort? void exch( std::string& a, std::string& b) { std::string tmp = a; a = b; b = tmp; } void bubble_sort( std::string A[], size_t size ) { size_t last_exch, left, right; while( size ) { for( left=0, right=1, last_exch=left; right<size; ++left, ++right) if( A[right]<A[left] ) exch( A[left], A[last_exch=right] ); size = last_exch; } } Clearly this is inefficient. A better approach would be to use an array of pointers to strings, and swap the pointers instead. The same can be said of any array of objects: use an array of pointers to the objects, never store the objects themselves in the array that is to be sorted.
What is Arrays of Pointers?
An array of pointers is a contiguous block of memory that contains pointers to other memory locations. They essentially allow non-contiguous memory locations to be treated as if they were an actual array.
Why array is a implicit pointer?
An array of pointers is exactly what it sounds like - one or more pointers arranged in order in memory, accessible through a common base name and indexed as needed. Philosophically, there is no difference between an array of pointers and an array of objects...int a[10]; // 10 integers, named a[0], a[1], a[2], ..., a[9]int *b[10]; // 10 pointers to int, named b[0], b[1], b[2], ..., b[9]If you initialize the array of pointers...int i;for (i = 0; i < 10; i++) b[i] = &a[i];... then *b[0] would be the same as a[0], etc.
What is the array of string in c?
A string in C is stored in a 1 dimension array so an array of strings is simply a two dimension array.
How many constructors are there for the string class?
The String class has multiple Constructors. Some of them are: 1. String - new String(String val) 2. Character Array - new String(char[] array) 3. Character Array with index positions - new String(char[] array. int start, int end)
What is array of string?
An array of strings is usually implemented as an array of character pointers. Each pointer refers to a a null-terminated character array, and can be treated just as if it were a two-dimensional array where the length of each "row" is not fixed length (the null terminator marks the end of each row). The array of character pointers must be allocated in contiguous memory (as must all one-dimensional arrays), however the character arrays they point to need not be allocated contiguously with each other (only the individual one-dimensional character arrays must be contiguous).
How do you convert a string into a character array?
A string is, by definition, a character array. No conversion is required.
What elements are in string?
A string is an array of characters.
Why would you use the array of pointers to pointers?
You would use an array of pointers to pointers whenever you wished to implement a dynamic multi-dimensional array of 3 or more dimensions. Every multi-dimensional array can ultimately be reduced to a one-dimensional array where each element is itself a one-dimensional array (an array of arrays). With fixed-size arrays, all elements can be allocated contiguously regardless of how many dimensions there are. Fixed size arrays can be allocated both statically (when the size is known at compile time) or dynamically (when the size is unknown at compile time). However with large arrays it is often necessary to divide the array into smaller subarrays each of which is allocated separately (non-contiguously with each other) and maintain a separate array of pointers to keep track of each of those subarrays. Although this consumes more memory than a contiguously-allocated array would, it has the added benefit in that each subarray need not be the same length, thus it can actually save memory overall. However, if we had several such arrays then we would need yet another array in order to keep track of them all, and this array would need to be an array of pointers to pointers.
