fgets () function is generally used to read the n-1 characters in the file into s , in fact, this function has a good use is to read the string from the standard input stream, And do not worry about the number of characters entered beyond the size of the character array, causing overflow problems! How do you do it? As follows:Char str[]; It is worth noting that: remember that fgets () reads only n-1 characters . therefore,fgets () reads the newline character, the end of the file, or the n-1 ch

get CPU usage through counters inside the CPU. In addition, you can visually obtain the program's speedup by comparing the execution time of the program. Note that the diagram in Windows Task Manager is unreliable, primarily because multiprocessor environments are complex, such as a dual-core processor with Hyper-Threading technology, when two full-load threads are executed in two physical cores, when Windows Task Manager reports a usage rate of 50% , it may be true that CPU utilization is 80~9
