Why not show output of this code.someone explain it.Thanks

Question

#include <string>
using namespace std;

int main() {
string a = "I am learning C++";
return 0;
}

Answer 1

Because you never printed the string.

#include <iostream>
#include <string>
using namespace std;

int main() {
string a = "I am learning C++";
cout << a;
return 0;
}

Answer 2

because you initialize a string variable but you don't print that... you need to include iostream (#include<iostream>) and print with cout ostream ... inside your main () cout<<a;
