Assuming i have a text file

```
ID       Name         A1      B1       C1     D1
1234567  Bob Persie   12.1    33.0     44.0   55.0
7654321  Tom Hard     12.2    13.0     31.0   3.0

```

I need to append the word:talking to the word: Tom so it will look like this

```
ID       Name         A1      B1       C1     D1
1234567  Bob Persie   12.1    33.0     44.0   55.0
7654321  Tomtalking Hard     12.2    13.0     31.0   3.0

```

I know i need to use the readt.seekp function to set the pointer to the position after the letter 'm' in the word: Tom. 

I have trouble determing the position of the letter 'm'.

readt.seekp(position, ios::beg);
