Assigning const std::string to std::string in c++

I am trying to assign a const std::string variable to std::string variable.But getting some memory related error. code is like below:

#include <iostream>
#include <string>

using namespace std;
std::string sender1;

std::string fun()
{
      const std::string sender = "hi";
       sender1.assign(sender);
      
}

int main()
{
    fun();
    cout<<sender1<<endl;
    return 0;   
}
Solution

  • You've forgotten a return in fun. If you change that function like this:

    std::string fun()
{
    const std::string sender = "hi";
    sender1.assign(sender);
    return sender;
}

    then the code will compile and run fine.
