C++ minimum string width

Question

Suppose I have ``` string a = "foo"; ``` How can I print `a` to the console using `printf` that ensure a minimum width, say, 10?

Accepted Answer

You can use `setw` manipulator to set the width of the output, like this:

```
cout << setw(10) << a << endl;
```

The `iomanip` header needs to be included in order for this to compile.
