This section contains a brief introduction to the C language. It is intended as a tutorial on the language, and aims at getting a reader new to C started as quickly as possible. It is certainly not intended as a substitute for any of the numerous textbooks on C. 2. write a recursive function FIB (n) to find out the nth element in theFibanocci sequence number which is 1,1,2,3,5,8,13,21,34,55,…3. write the prefix and postfix form of the following infix expressiona + b – c / d + e * f – g * h / i ^ j4. write a function to count the number of nodes in a binary tr
C# BigInteger class. BigInteger.cs is a csharp program. It is the BIgInteger class. It has methods: abs() , FermatLittleTest(int confidence) ,gcd(BigInteger bi) , genCoPrime(int bits, Random rand) , genPseudoPrime(int bits, int confidence, Random rand) , genRandomBits(int bits, Random rand) , isProbablePrime(int confidence) , isProbablePrime() , Jacobi(BigInteger a, BigInteger b) , LucasSequence(BigInteger P, BigInteger Q, BigInteger k, BigInteger n) ,max(BigInteger bi) , min(BigInteger bi) , modInverse(BigInteger modulus) , RabinMillerTest(int confidence) ,
學生成績管理
假設有一個班級的學生n人，期末考試老師要對成績從高到低列出，并對各科的考試成績求出其最高分、最低分和平均成績。現(xiàn)在設計一個成績管理程序，能夠?qū)崿F(xiàn)以下的功能：
（1）對某門科目的成績進行排序并顯示輸出；
（2）求出每門科目的最高分、最低分和平均分的信息；
學生成績的數(shù)據(jù)用結(jié)構(gòu)數(shù)組表示，包括：學號、姓名、三門科目的考試成績，其結(jié)構(gòu)格式如下：
學號 姓名 語文 數(shù)學 外語 C++
int num char name[10] int score[4]
