pointer-to-pointer (double pointer). "pass by pointer“ of function parameter means passing a pointer by value In most cases, no problem! Problem comes when modifying the pointer inside the function In this case, we need pointer-to-pointer. int g_One=1; void func(int* pInt); int main() {

void *. Why did we use them in C? Why are they dangerous in C?. Tagged unions. Why did we use them in C? Why are they annoying in C?. Interface. A set of methods only If a class implements an interface, that is a guarantee it has all of that specific set of functions.
Func ţii. Funcţia este un program care poate să execute operaţii complexe şi care furnizează un rezultat ce poate fi folosit ca operand într-o expresie. Fiecare funcţie se identifică printr-un nume. Referirea la o funcţie se face astfel : Nume_funcţie(listă_de_argumente)
