how to set char * value from std string (c_str()) not working

Question

i dont know but this not working for me im getting garbege value when i try to set char * value from function that returns std string :

string foo()
{
  st         


        

Answer 1

Pass a memory location to foo() and have foo modify that:

void foo (string* _out_newStr)
{
    _out_newStr->assign("dummy string"); //This is wrong -> _out_newStr = "dummy string";
    return;
}

Then when you are using the "c_str()" function of the string object you will return a const char* value, as already pointed out.
