他三种方式产生实际值的确界。P28 Code and operationSecond, the problems encountered and how to solveThis week's course is mainly the reading and comprehension of textbooks, and the proportion of experiments is small.With regard to the application of bit patterns, it was doubtful at first that the concept of coercion was not clear. After further understanding, you slowly begin to understand the actual concept of coercion. It is known that coercion type conversions cannot be transferred arbitrarily.This week, we

double. On machines that support IEEE floating-point format, these data types correspond to single-precision and double-precision floating-point.The newer version of the C language, including the ISO C99, contains the third floating-point data type long double. For many machines and compilers, this data type is equivalent to a double data type. However, for Intel compatible machines, GCC uses the 80-bit "extended precision" format to implement this data type, providing a much larger range and p

particular trajectory through the execution state space, forgetting a guideline that the threaded program must work correctly for any viable trajectory.2. Elimination Method:Dynamically assigns a separate block to each integer ID, and passes to the thread routine a pointer to the block4. Deadlock1. A set of threads is blocked, waiting for a condition that will never be true. Programmers use P and V to operate improperly so that the forbidden areas of two semaphores overlap. Overlap
