The output of the code will be "h123ello".

Here's the step by step explanation:

1. A string "hello" is created and assigned to the variable `str`.
2. The `insert()` function is called on `str`. This function inserts the string "123" at the position 1 of `str`. The position of the characters in a string is zero-based, which means the first character is at position 0, the second character is at position 1, and so on. So, "123" is inserted after the first character 'h'.
3. The `cout` statement prints the modified string `str` to the console.

So, the output is "h123ello".
