ARM下 Implement matrix multiplication of 2 square matrices, with data read from an input file and printed both to the console and to an output file. • Assume a file with correct data (no garbage, characters, etc.). • you must check and provide appropriate execution for 2 extra cases, namely when the matrix size given is either “0” , or when the size is greater than the maximum handled of “5” . In these 2 cases you must implement the following behaviour: o If size = 0, then print a message “Size = 0 is unacceptable” and continue by reading the next size for the next 2 matrices (if not end of file). o If size >5, then print two messages: “Size is too big - unacceptable”. Then read and discard the next (size2 ) integers and continue by reading the next size for the next 2 matrices (if not end of file).

數字運算，判斷一個數是否接近素數 A Niven number is a number such that the sum of its digits divides itself. For example, 111 is a Niven number because the sum of its digits is 3, which divides 111. We can also specify a number in another base b, and a number in base b is a Niven number if the sum of its digits divides its value. Given b (2 <= b <= 10) and a number in base b, determine whether it is a Niven number or not. Input Each line of input contains the base b, followed by a string of digits representing a positive integer in that base. There are no leading zeroes. The input is terminated by a line consisting of 0 alone. Output For each case, print "yes" on a line if the given number is a Niven number, and "no" otherwise. Sample Input 10 111 2 110 10 123 6 1000 8 2314 0 Sample Output yes yes no yes no

這個例子如果運行,將在仿真的PC窗口中的第1,2,3行顯示一些信息后,在隨機位置顯示 1 ~ 5 .由于keil c51默認不支持重入函數,它的重入函數使用仿真的重入棧而不使用系統棧,而Small RTOS 51沒有進行重入棧管理,所以在TaskA~TaskE雖然及其相似,但不能合并. 注意:(1)在KEIL C51 工程中,我已經把輸出文件目錄設在e:\temp中,您可以在Project->Options for Target "Target 1"的output頁點擊Select Folder for Objects...和Listing頁點擊Select Folder for Listing...改變. (2)編譯時會有5個警告,其中一個是因為沒有使用一個系統函數OSSendSignal引起,它可以忽略.另4個是禁止任務間變量覆蓋分析引起,必須忽略.感謝網友John X. Liu,在這個例子中我使用了他編寫的仿真(dllPc51Emu.dll),這個dll原來是為他移植的Ucos-ii for keil c51的例子編寫. (3)Pc51Emu.dll在KEIL C51 V6.23 V7.00工作不正常.

這個例子是例子2的另一種寫法（但任務數量不同）,它使用了最高優先級任務作為顯示任務,全局變量ShowChar作為參數.函數TaskB是優先級1~10的任務函數,因為沒有使用局部變量,這些任務可以用一個函數. 注意:(1)在KEIL C51 工程中,我已經把輸出文件目錄設在e:\temp中,您可以在Project->Options for Target "Target 1"的output頁點擊Select Folder for Objects...和Listing頁點擊Select Folder for Listing...改變. 感謝網友John X. Liu,在這個例子中我使用了他編寫的仿真dll(Pc51Emu.dll),這個dll原來是為他移植的Ucos-ii for keil c51的例子編寫. (2)Pc51Emu.dll在KEIL C51 V6.23 V7.00工作不正常.

2^x mod n = 1 acm競賽題 Give a number n, find the minimum x that satisfies 2^x mod n = 1. Input One positive integer on each line, the value of n. Output If the minimum x exists, print a line with 2^x mod n = 1. Print 2^? mod n = 1 otherwise. You should replace x and n with specific numbers. Sample Input 2 5 Sample Output 2^? mod 2 = 1 2^4 mod 5 = 1
