_memccpy
void *_memccpy(
void *dest,
const void *src,
int c,
size_t count
);

Parameters
dest
Pointer to the destination.

src
Pointer to the source.

c
Last character to copy.

count
Number of characters.

Return Value
If the character c is copied, _memccpy returns a pointer to the char in dest that immediately follows the character. If c is not copied, it returns NULL.


```cpp
#include <memory.h>
#include <stdio.h>
#include <string.h>
#include<iostream>

using namespace std;

int main(void)
{
	//char buffer[41] = { '0' };

	char string1[20] = "The qkhh";
	***char buffer[5] = { '0' };***
	char *pdest;

	printf("Function: _memccpy 60 characters or to character ' '\n");
	printf("Source: %s\n", string1)
