Assigning Strings with Initializer Lists
- Can you explain to me why there are differences?
- What does it mean
PKcE
?
code:
#include <iostream>
#include <typeinfo>
using namespace std;
int main() {
string s {"IDE"};
std::cout<<typeid(s).name()<<std::endl;
auto S{"IDE"}; // why do not deduced as string?
std::cout<<typeid(S).name()<<std::endl;
auto c = {"IDE"}; // why do not deduced as string?
std::cout<<typeid(c).name()<<std::endl;
auto C {string{"IDE"}}; // why do not deduced as string?
std::cout<<typeid(C).name()<<std::endl;
auto Z = string{"IDE"};
std::cout<<typeid(Z).name()<<std::endl;
}
output:
Ss
St16initializer_listIPKcE
St16initializer_listIPKcE
St16initializer_listISsE
Ss

string s {"IDE"}; // Type of s is explicit - std::string
auto S{"IDE"}; // Type of S is an initializer list consisting of one char const*.
auto c = {"IDE"}; // Type of c is same as above.
auto C {string{"IDE"}}; // Type of C is an initializer list consisting of one std::string
auto Z = string{"IDE"}; // Type of Z is std::string
I don't know what it means PKcE
. I can only guess what P
Pointer K
stands for , stands for const, c
stands for symbol. I don't know what it meant E
.
