Reading/Writing integer values on a string object
<p>I have the contents of a file assigned into a string object. For simplicity the file only has 5 bytes, which is the size of 1 integer plus another byte.
What I want to do is get the first four bytes of the string object and somehow store it into a valid integer variable by the program.
Then the program will do various operations on the integer, changing it.
Afterward I want the changed integer stored back into the first four bytes of the string object.</p>

<p>Could anyone tell me I could achieve this? I would prefer to stick with the standard C++ library exclusively for this purpose. Thanks in advance for any help.</p>
