Function pointers

Assume there are some functions

int func(int a, double b);
int fonc(int a, double b);

To create a pointer to these functions:

int(*p)(int, double);

p = func;

(*p)(1, 1.22);

/* or */

p = fonc;

p(2, 3.44) ;

Note: All functions that are used with the same function pointer must have the same parameters and return type.

Lazy evaluation
Assume we have an array with 10 elements
and we want to print only those are greater than 3
so
int arr[10] = {1,2,3,4,5,2,7,2,5,9};
for(int i = 0; i < 10; i++){
arr[i]>3 && printf("%d \n", a[i]); /* the second part of the condition is evaluated only when the first one is true */
}
