typeid Operator - Type Casting
How is typeid operator used in C++?
Explanation
typeid operator is a type casting method which is used to check the type of an expression. In C++, the typeid keyword is used to determine the class of an object at runtime
Result :
The type of a is: int
The type of c is: char *
In the above example the "typeid" is used to find the data type.
Example :
| #include <iostream.h> #include <typeinfo.h> int main() { int a; char *c; cout << "The type of a is: " << typeid(a).name() << endl; cout << "The type of c is: " << typeid(c).name() << endl; return 0; } |
Result :
The type of a is: int
The type of c is: char *
In the above example the "typeid" is used to find the data type.
