Const-cast Typecast
Const casts are only available in C++. Const casts are used to strip the
const-ness or volatile-ness from a variable. Const casts should be used
sparingly; one example of a valid use of a const-cast is to strip the
const-ness of a pointer to pass it into a function when you are certain the
function will not modify the variable but the function designer did not
specify the input as const.
const_cast<<type>>(<value>);
This example casts a const pointer to a non-const pointer to pass into a
function:
void func(char *);
const char *x = "abcd";
func(const_cast<char *>(x));
