how to solve pointer problem?

In the following code :-

#include<iostream>
using namespace std;

main()
{
char*pch = new char[10];

pch = "rahul";
// this statement causees memory leak error when deleting pch
delete pch;

return 0;
}

what should I do so that we can avoid aboe error
BUT I want to use only pointer and don't want to use
in built C functions or C++ in built classes such as string.

I think you should use 'delete pch[];' for such (array) cases.

Try memcpy(pch, "rahul", 5) instead of pch = "rahual".
