strange situation in file

Hi All,

I am writing some data's into a file from C++ program. The files which i am writing is of fixed length . say 232 in length per line.
I am writing as . my c code is as

sprintf(szData1,"%.6d%-30s%-6s%-30s%-3s",m_nBrandCode,m_BrandDescription30.data(),m_SizeCode.data(),m_SizeValue.data(),m_MultiValue.data( ));
sprintf(szData3,"%.4d%.4d%-8s%-6s%-6s%-6s%-6s",m_nTgmModuleNumber,m_nTgmProductGroupCode,m_OldestSalesDate.data(),m_ContrCharCode.data(),m_Genr eCharCode.data(),m_VdfmtCharCode.data(),m_TypeCharCode.data());

But after the file operation finished when i cheked the file the file is not in
fixed line length there are some junk character after the new line ("\n")
i mean that some lines are with 232 in length and some are with 233 in length . When i tried convert the line into HEXA decimamal value it is showing a apecial charater 00.

Why that is happening . PLease let me know
