### Examples Using the Comma Operator ( , )

The table below gives some examples of the uses of the comma operator:

Statement | Effects
--- | ---
    for (i=0; i<2; ++i, f() );
| A for statement in which `i` is incremented and `f()` is called at each iteration.
    if ( f(), ++i, i>1 )
       { /* ... */ }
| An if statement in which function `f()` is called, variable `i` is incremented, and variable `i` is tested against a value. The first two expressions within this comma expression are evaluated before the expression `i>1`. Regardless of the results of the first two expressions, the third is evaluated and its result determines whether the if statement is processed.
    func( ( ++a, f(a) ) );
| A function call to `func()` in which `a` is incremented, the resulting value is passed to a function `f()`, and the return value of `f()` is passed to `func()`. The function `func()` is passed only a single argument, because the comma expression is enclosed in parentheses within the function argument list.
