How can I call a function using a function pointer?

Question

Suppose I have these three functions:

bool A();
bool B();
bool C();

How do I call one of these functions conditionally using a function poi

Answer 1

Slightly different approach:

bool A() {...}
bool B() {...}
bool C() {...}

int main(void)
{
  /**
   * Declare an array of pointers to functions returning bool
   * and initialize with A, B, and C
   */
  bool (*farr[])() = {A, B, C};
  ...
  /**
   * Call A, B, or C based on the value of i
   * (assumes i is in range of array)
   */
  if (farr[i]()) // or (*farr[i])()
  {
    ...
  }
  ...
}
