GDB allows you to view the internal structure of the program, print the variable value, set the breakpoint, debug the source code in a single step, modify the variable value during running, track the path, switch the thread, and display the assembly code.Compile To use GDB for debugging, you must add the

Simulate your database carefully Program Have you found that database data is frequently read repeatedly during computing (especially during multi-user computing ?! This is the primary killer of database processing program performance. Some people say that before writing a programAlgorithmMake sure that the data records are read in batches and at one time.
