Reallocating Memory for dynamic character array

[shaynerossum]

I'm trying to allocate memory delete it and then allocate it again with more, less, or the same. I've tried this several different ways, but I don't know how to do it or if it can be done with any similarity to my attempts. In my test program it should try to reallocate the same amount of memory, but in my actual program this will prove untrue.

Thank You for your Time.

// Test Program built to troubleshoot Reallocation of Memory
#include<iostream>
using namespace std;

void makelong(char* pagepass[],char pass2[], char pass1[],char *subpass[], int size);
int make1(char *pass1[], char **pagepass, char **dir,int run);
int make2(char *pass2[], char **pagepass, char **subpass, char **dir);

int main()
{
//Main is built from scratch and is passed varibles that will look like those obtained in the actuall program
char **pagepass, pass2[50] = "C:\\InputData\\", pass1[50] = "C:\\OutputData\\", **subpass; int size = 4, x;
pagepass = new char*[3];
for(x=0;x<3;x++)
	pagepass[x] = new char[20];
pagepass[0] = "something0.html";pagepass[1] = "something1.html";pagepass[2] = "something2.html";
subpass = new char *[size];
for(x=0;x<size;x++)
	subpass[x] = new char[30];
subpass[0] = "dirOne"; subpass[1]= "dirTwo"; subpass[2]= "dirThree"; subpass[3]= "dirFour";
makelong(pagepass, pass2, pass1, subpass, size);

}
