It makes one flight daily. Write a seating reservation program with the following features: The program uses an array of 12 structures. Each structure should hold a seat identification number, a marker that indicates whether the seat is assigned, the last name of the seat holder, and the first name of the seat holder. The program displays the following menu:To choose a function, enter its letter label: a) Show number of empty seats b) Show list of empty seats c) Show alphabetical list of seats d) Assign a customer to a seat assignment e) Delete a seat assignment f) Quit The program successfully executes the promises of its menu. Choices d) and e) require additional input, and each should enable the user to abort entry. After executing a particular function, the program shows the menu again, except for choice f). Data is saved in a file between runs. When the program is restarted, it first loads in the data, if any, from the file.

The first is the name of a file; the second is  a string . The program should then search the file, printing all  lines  that contains the string  Mon, 02 Apr 2012 17:38:28 +0800 http://lms.xms.com.tw/board.php?courseID=143&f=doc&cid=8162 1) 寫一個show_bitmap函式可將二維陣列的值輸出，輸出方式:當bit為1時輸出’*’,0輸出空白字元’  ’，每處理完2個byte輸出換行'\n' void show_bitmap(int (*a)[30],int row);char array[2][30]={0x8,0x20,0x8,0x24,0xfe,0xfe,0x8,0x20, 0x0,0x0,0x8,0x20,0x4,0x40,0x4,0x40, 0x2,0x80,0x1,0x0,0x2,0x80,0xc,0x70, 0x30,0xe,0xc0,0x4,0x0,0x0},{0x20,0x20,0x51,0xfc,0x88,0x88,0x0,0x50,0xfb,0xfe,0x22,0x22,0x22,0x22,0xf9,0xfc,0x21,0x24,0x21,0x24,0xa9,0x24,0x71,0x2c,0x20,0x20,0xf8,0x20,0x0,0x0}}; Fri, 30 Mar 2012 18:34:20 +0800 http://lms.xms.com.tw/board.php?courseID=143&f=doc&cid=8155 1) Write and test a Fibonacci() function that uses a loop instead of recursion to calculate Fibonacci numbers.f(n)=f(n-1)+f(n-2) if n > 2f(n)=n             if  0<=n<=2 2) Write a routine that rotates the bit pattern for the character c left b bits.   unsigned char rotate_left(unsigned char c, unsigned char b)         ex.  rotate_left(0xa3,2) returns 0x8e           3) Write a to_base_n(int number,int base) function which prints the number that is its first argument to the number base given by the second argument. For example, to_base_n(129,8) would display 201, the base-8 equivalent of 129. Please implement to_base_n() function in Recursive version and Non-recursive version. Wed, 28 Mar 2012 17:39:10 +0800 http://lms.xms.com.tw/board.php?courseID=143&f=doc&cid=8139 Write  a  program  that  prints the  following  diamond  shape.  Your  program  should  read  an  odd  number  in  the  range  1  to  51  to  specify  the  number  of  rows  in  the diamond, and then display a diamond of the appropriate size.    You  may  use  output  statements  that  print  either  a  single  asterisk  (*) or  a  single blank. Maximize your use of repetition (with nested for statements) and minimize the number of output statements.         *        ***       *****      *******     *********    ***********     *********      *******       *****        ***         * Sat, 24 Mar 2012 22:13:54 +0800
