Question Debug C++ String

[tuxprocesor]

Hello!
I want to start a new project that read a string of c++ code and debug it to tell me if they have errors.

Example: i have a Windows form/Website with a Textbox and a Button.
i need to write in the textbox
Example:
If var then
{
printf()
}

and press the button and debug it and i need to know that i miss a ; and the =.

i really don't know where to start, do anyone have something that can help me with this ?

Thanks So much for the help!
