計(jì)算機(jī)等級(jí)考試三級(jí)數(shù)據(jù)庫(kù)技術(shù)上機(jī)考試內(nèi)容

　　分析：根據(jù)題意分析得出：本題主要考查考生的字符串指針或字符串?dāng)?shù)組以及根據(jù)公式進(jìn)字符的ASCII值運(yùn)算，再根據(jù)運(yùn)算結(jié)果和條件進(jìn)行相應(yīng)的替代操作，要求考生僅編寫函數(shù)encryptChar()實(shí)現(xiàn)轉(zhuǎn)換功能。其中輸入及輸出函數(shù)給出且已調(diào)用，考生不必自己編寫。

　　編寫函數(shù)encryptChar()的程序內(nèi)容如下：

　　void encryptChar()

　　{ int i, j, val ;

　　for(i=0 ; i

　　for(j=0 ; j

　　val=(xx[i][j]*11) % 256 ;

　　if(! (val<=32 || val>130)) xx[i][j]=val ;

　　}

　　}

　　數(shù)據(jù)文件IN.DAT內(nèi)容如下：

　　You may WANT A FIELD in field in each record to uniquely identify that1234

　　record from all other records IN THE FILE. For example, the Employee123456

　　Number field is unique if you DO NOT ASSIGN the same number to two12345678

　　different employees, and you never reassign THESE NUMBERS to other12345678

　　employees. If you wish to FIND OR MODIFY the record belonging to a11111111

　　specific employee, this unique FIELD SAVES the thouble of determining22222

　　whether you have the correct record.12345678901234567

　　If you do not have a unique field, YOU MUST FIND THE first record123456787

　　the matches your key and determine whether THEN RECORD is the one you33333

　　want. If it is not the CORRECT ONE, you must search again to find others.4
