The following code snippet is supposed to output “true” if the string “c++” is in the map and false otherwise. However, it has an error. Describe the error and give a fix.
What will be an ideal response?
```
if (mymap["c++"]==0)
{
cout << "false" << endl;
}
else
{
cout << "true" << endl;
}
```
The expression mymap["c++"] creates a new association if one does not
already exist. To see if something is in the map we should use the find method,
which returns m.end() if there is no such element:
