by Long LuoPersonal blog LinksRecently in the study Java多线程 , encountered a following pen question, the topic is as follows:编写一个程序，程序会启动4个线程，向4个文件A，B，C，D里写入数据，每个线程只能写一个值。 线程A：只写A 线程B：只写B 线程C：只写C 线程D：只写D 4个文件A，B，C，D。 程序运行起来，4个文件的写入结果如下： A：ABCDABCD... B：BCDABCDA... C：CDABCDAB...

1. Read-write character function putc () and getc () These two functions are similar to the Putchar () and the GetChar () functions. Assuming FP is a file pointer, ch is a character variable, ch = getc(fp);// ch = getchar(); putc(ch,fp);// putchar(ch); C implementation that outputs the contents of a file (by character) to the standard output: #include #include /* 将文件内容(按字符)输出到标准输出 */ void read_ch(char * filename, char * mode) { 　　　　int ch; 　　　　F

reference elements, can choose the intermediate elements of the array, you can randomly get three elements, and then select the middle element (three number median method).Another thing is that when we split up, if the length of the split sub-sequence is small (less than 5 to 20), the efficiency of the recursive sorting is not as fast as the insertion sort or the hill sort. So you can judge the length of the array, if it is less than 10, directly with the insertion sort, instead of recursively
