    • If function contain static variables.
    • If function returning value consists looping construct.
    • If inline functions are recursive.
    Inline functions provide following advantages:
    • It reduces Function call overhead.
    • It reduces overhead of a return call from a function.
    • Inline functions are best for small functions
    The syntax for defining the function inline is:
    inline return-type function-name(parameters)
    {
    // function code
    }
