String counter doesn't count the appropriate strings properly
I have this source code that is supposed to count the repeated occurrences of certain strings in the text file, "string.txt". The contents of the file are listed below:
AA-AB-AC-AG-AE-AL
AL-AQ-AE-AN-AO-AM
AM-AQ-AO-AA-AB-AC
AD-AJ-AK-AI-AM-AO
AN-AH-AC-AA-AP-AQ
AP-AP-AN-AN-AL-AP
AN-AD-AU-AE-AH-AQ
AK-AQ-AE-AL-AE-AA
AA-AJ-AB-AG-AE-AF
AF-AE-AL-AI-AP-AM
AU-AF-AJ-AV-AI-AM
AP-AI-AQ-AK-AB-AC
AU-AN-AL-AF-AO-AB
AM-AA-AN-AM-AH-AO
AP-AQ-AJ-AD-AN-AI
AG-AU-AO-AD-AF-AI
AQ-AM-AN-AB-AC-AK
AN-AB-AI-AL-AE-AJ
AB-AA-AP-AQ-AH-AD
AC-AL-AG-AU-AJ-AM
AL-AP-AB-AM-AA-AC
AD-AE-AA-AC-AL-AB
AO-AN-AQ-AK-AM-AQ
AE-AI-AC-AH-AD-AJ
AJ-AN-AM-AK-AL-AP
But as I checked it against the actual contents, the output program isn't counting the occurrences properly.
Instead of going through 10 lines as needed, it seems that it is skipping some lines.
I have made two versions of the code where the placement of the break statement varies. But in both versions, the same problem persists (that is, the occurrences aren't counted properly)."AH" and "AI" are supposed to be counted since they are within the required first 10 lines - but for some reason, they aren't included...
output for version01 source.jpg
output for version02 source.jpg
I couldn't place the break statement anywhere in the code without causing an error. Is there something I missed out? Here are two versions of the code by the way:
