Parsing Input as String using sscanf

I'm parsing an input of string using sscanf. I found that the way sscanf behaves is funny.

My input of String looks as follows :-

1000Prasun K 1004BANGL0

Initially I used the following command to parse the input :-

scanf (acEmpRecord, "%d%[^0-9]25s%d%5s%d",
&iEmpId, acEmpName, &iDeptCode, acLocation, &iTelExt);

and I get -> 1 1000 Prasun K ╠╠╠╠╠╠╠╠Prasun K -858993460.

Supposedly, my the output should look like :-

1 1000 Prasun K BCMD BANGL -

To solve the above problem, I've removed 25s from the sscanf and the command look likes the below statement.

sscanf (acEmpRecord, "%d%[^0-9]%d%5s%d",
&iEmpId, acEmpName, &iDeptCode, acLocation, &iTelExt);

I managed to get the intended output.
