<p>How should I use array of function pointers in C?</p>

<p>How can I initialize them?</p>

You have a good example
here (Array of Function pointers)
, with the
syntax detailed
.
```
```
int sum(int a, int b);
int subtract(int a, int b);
int mul(int a, int b);
int div(int a, int b);

int (*p[4]) (int x, int y);

int main(void)
{
  int result;
  int i, j, op;

  p[0] = sum; /* address of sum() */
  p[1] = subtract; /* address of subtract() */
  p[2] = mul; /* address of mul() */
  p[3] = div; /* address of div() */
[...]
```
```
To call one of those function pointers:
```
```
result = (*p[op]) (i, j); // op being the index of one of the four functions
```
```
