Yes.  In C, the syntax of an if statement is
    "if" "(" <condition> ")" <statement>

A <statement> may be a single statement or it may be a brace-enclosed
block.

If you expect to proceed along these lines I really have to urge you
to learn C.  C is a simple language, easy to learn if you already know
how to program.  (C++, on the other hand, is quite complex.)
