C++, Progam Detection -

i want detect if window/process running, , if does, make c++ program close.

something this:

    if (findwindow(null, text("fiddler"))) {         ;         std::exit              ;     }

it doesn't works reason.

why have random semi-colons floating in space?

this code should like:

if (findwindow(null, text("fiddler")) != null) {     std::exit(0); }
