C Programming language

Nesting of Function using C

C permits nesting of two functions. There is no limit how deeply functions can be nested. Suppose a function abc can call function bca and function bca can call function cab and so on.

void f(void)
{
    // Declare a function called g
    void g(void);

    // Call g
    g();
}

// Definition of g
void g(void)
{
}
