How to pass a pointer to a dynamic array to a void function?
<p><B>Updated question to reflect answers and my research</b></p>

<p>Thanks casablanca and wallyk for answering. Success!! I ended up having to edit my strcpy and strcat as well as changing my Displayname(char c_fullname) function and researching some more about the additional errors (both complier and runtime) I was getting, but now I have working code!! Thanks to everyone for your help and patience. My final problem was that I was supposed to write my function declaration and implementation (but not my function call) as "Displayname(char* c_fullname)" not "Displayname(char *c_fullname)". Simple mistake but definitely a costly one as my program was not passing the strings completely. Again thanks to everyne for their help. I know I would have gotten this far without it.</p>

<p>I am posting my completed working code below for anyone else who may have the same issue:</p>

<pre><code>#include &lt;iostream&gt;
#include &lt;cstring&gt;
using namespace std;

void DisplayName(char* c_fullname);

int main()
{
//Declaration of variables
const int n_SIZE = 25;          //Size declaration for first, middle, and last name arrays
char c_firstname[n_SIZE];       //Firstname array
char c_middlename[n_SIZE];      //middlename array
char c_lastname[n_SIZE];        //lastname array
int n_namesize = 0;             //size declaration for dynamic array
char *c_fullname;               //pointer for fullname. Later will be allocated an array size
bool b_test = true;             //while loop test value
char c_exittest;                //test value for user prompt

//Explanation of program to user
cout &lt;&lt;"This program inputs a user's first, middle, and last name.\nNext, the names are dynamically allocated to a single array\nand printed to the screen" &lt;&lt;endl &lt;&lt;endl;

while (b_test == true)
{
    cout &lt;&lt;"Please enter a first name: ";   //User inputs firstname
        cin &gt;&gt;c_firstname;
    cout &lt;&lt;"Please enter a middle name: ";  //User inputs middlename
        cin &gt;&gt;c_middlename;
    cout &lt;&lt;"Please enter a last name: ";    //User inputs lastname
        cin &gt;&gt;c_lastname;
    cout &lt;&lt;endl;                            //endl for aesetics

    //Testing of stored variables
    /*
    cout &lt;&lt;c_firstname;
    cout &lt;&lt;c_middlename;
    cout &lt;&lt;c_lastname;
    cout &lt;&lt;endl &lt;&lt;endl;

    cout &lt;&lt;strlen( c_firstname ) &lt;&lt;endl; 
    cout &lt;&lt;strlen( c_middlename ) &lt;&lt;endl; 
    cout &lt;&lt;strlen( c_lastname ) &lt;&lt;endl;
    */


    //setting size of n_namesize for length of array name[]
    n_namesize = (strlen(c_firstname) + strlen(c_middlename ) + strlen( c_lastname ) + 3);   //strlen used to determine length of each element + 3 for spaces
    c_fullname = new char[n_namesize];          //allocates memory to dynamic array 

    //Testing of n_namesize
    //cout &lt;&lt;n_namesize &lt;&lt;endl &lt;&lt;endl;

    //Concatenating strings to array fullname[n_namesize]
    strcpy_s(c_fullname, n_namesize, c_firstname );     //copies firstname to fullname
    strcat_s(c_fullname, n_namesize, " ");              //concatenates space to fullname
    strcat_s(c_fullname, n_namesize, c_middlename);     //concatenates middlename to fullname
    strcat_s(c_fullname, n_namesize, " ");              //concatenates space to fullname
    strcat_s(c_fullname, n_namesize, c_lastname);       //concatenates lastname to fullname

    //Testing of fullname[]
    //cout &lt;&lt;"Name: "&lt;&lt;c_fullname &lt;&lt;endl &lt;&lt;endl;

    //Passing pointer of array to function
    DisplayName(c_fullname);

    //Prompt users to enter a new name
    cout &lt;&lt;"Do you wish to enter a different name?" &lt;&lt;endl;
    cout &lt;&lt;"Enter 'y' for yes, or 'n' for no" &lt;&lt;endl;
    cin &gt;&gt;c_exittest;

    //User wants to enter a new name
    if (c_exittest == 'y')
    {
        delete[] c_fullname;    //deallocates memory assigned to array
    }

    //User does not want to enter a new name
    if (c_exittest == 'n')
    {
        b_test = false; //exits while loop
    }
}
}
void DisplayName(char* c_fullname)

cout &lt;&lt;"The full name entered is: "&lt;&lt;c_fullname &lt;&lt;endl;

<p>Hey everyone,</p>

<p>Thanks for your previous help. I have another assignment (past due) that is giving me problems. I think the assignment is to pass a pointer of a dynamic array to a function which then will display the strings. My instructions is to " pass the constructed array to a function called void DisplayName(char * Name)" However, I keep getting errors. My code is:</p>

<pre><code>#include &lt;iostream&gt;
#include &lt;cstring&gt;
using namespace std;

void DisplayName(char *c_fullname);

int main()
{
//Declaration of variables
const int n_SIZE = 25;      //Size declaration for first, middle, and last name arrays
char c_firstname[n_SIZE];       //Firstname array
char c_middlename[n_SIZE];      //middlename array
char c_lastname[n_SIZE];        //lastname array
int n_namesize = 0;          //size declaration for dynamic array
char c_fullname[100];           
     //fullname array. size initialy set to 100
char *c_pointer;                //pointer for dynamic array
bool b_test;                     //while loop test value
char c_exittest;                //test value for user prompt

//Explanation of program to user
cout &lt;&lt;"This program inputs a user's first, middle, and last name.\nNext, the names are dynamically allocated to a single array\nand printed to the screen" &lt;&lt;endl &lt;&lt;endl;

while (b_test = true)
{
    cout &lt;&lt;"Please enter a first name: ";   //User inputs firstname
        cin &gt;&gt;c_firstname;
    cout &lt;&lt;"Please enter a middle name: ";  //User inputs middlename

        cin &gt;&gt;c_lastname;
    cout &lt;&lt;endl;                            //endl for aesetics

<p>my error is: 
error C2664: 'DisplayName' : cannot convert parameter 1 from 'char' to 'char *'</p>

<p>I have tried to change several parts to make it work, all of which give me other errors. At this point I am really stuck, so looking for some advice. 
Thanks in advance for your help,</p>
