cpp type casting code example

Example 1: casting C++

int main()
{
  short a = 2000;
  int b;
  b = (int)a; // c-like cast notation
  b = int(a); // functional notation
}

Example 2: c++ casting

static_cast:
//does implicit conversions between types.
void* data;
pointer *pData = static_cast<pointer*>(data);

const_cast:
//this can be used to remove or add the const to a variable.
const char* characters;
const_cast<char*>(characters);

reinterpret_cast:
//this cast is dangerous since it turns one type directly into another.
struct S1 { int a; } s1;
int* p1 = reinterpret_cast<int*>(&s1);
