C++ » Class » cast Screenshots  The const_cast operator is used to explicitly override const and/or volatile in a cast.     #include <iostream> using namespace std;     void sqrval(const int *val){   int *p;       // cast away const-ness.   p = const_cast<int *> (val);       *p = *val * *val; // now, modify object through v }     int main(){   int x = 10;       cout << "x before call: " << x << endl;   sqrval(&x);   cout << "x after call: " << x << endl;       return 0; }                 Related examples in the same category 1.
