说明: Owing to the broad application value of audio
watermarking in remote transmission and mobile
extraction, it is very important to study watermarking
approaches against A/D and D/A conversion. Based
on wavelet decomposition and cepstrum technology,
an audio watermarking algorithm is proposed where
the low-frequency wavelet coefficients are chosen for
cepstrum transforming. Then, the obtained cepstrum
data shows stable for watermark hiding by the
methods of edging data cutting and statistical mean
modification. The synchronization is not required in
the algorithm. Experimental results show that the
proposed algorithm can resist on the attack of A/D
and D/A successfully with features of large capacity
and zero bit error. It will be helpful for the mobile
audio in secure broadcast and management in the

c语言实现,能够输入和查询客户存款取款记录。在客户文件中,每个客户是一条记录,包括编号、客户姓名、支取密码、客户地址、客户电话、账户总金额;在存取款文件中,每次存取款是一条记录,包括编号、日期、类别、存取数目、经办人。类别分为取款和存款两种。本系统能够输入客户存款或取款记录;根据客户姓名查询存款和取款记录。(c language, be able to enter and query the records of customer deposit withdrawals. , Each customer is a record in the customer file, including the number, customer name, withdraw the password, the customer address, customer phone account the total amount in the deposit file, each deposit is a record, including the number, date, category, access the number of managers. The categories are divided into two kinds of withdrawals and deposits. The system can enter the customer deposits or withdrawals records their deposits and withdrawals recorded according to the customer' s name.)
