char () and int () are functions in c++? : <p>after 30 min of googling I decided to ask here my doubt 
It maybe invalid question if I am not understanding below line of code correctly </p>

<p><code>result += char(int(text[i]+s-65)%26 +65);</code></p>

<p>In above code char() is a function ? If yes so I am unable to find any information about it and if no so what is this ?
And same doubt for inner int() .</p>

<p>Above code is copied from a C++ program.</p>
