typeid to string c++
To convert the typeid
to a string in C++, you can follow these steps:
Include the necessary header file:
cpp #include <typeinfo>
Use
typeid
to get the type information of an object or a type. For example, let's say we have an object calledobj
:cpp int obj;
Using typeid to Convert Type Information to String in C++
#include <iostream>
#include <typeinfo>
int main() {
int x = 5;
const std::type_info& type = typeid(x);
std::cout << "Type of x: " << type.name() << std::endl;
return 0;
}
Explanation
Include Necessary Headers: Include the necessary headers for the program, such as iostream and typeid.
Declare Main Function: Declare the main function, which is the entry point of the program.
Declare Variable: Declare a variable
x
of type int and initialize it with the value 5.Get Type Information: Use the
typeid
operator to get the type information of the variablex
and store it in a reference tostd::type_info
namedtype
.Print Type Information: Print the type of
x
usingtype.name()
and output it to the console.Return Statement: Use the return statement to end the main function and return 0 to indicate successful execution.
