pair Programming Photos: Code 3.1 cannot trigger fault Construction Example: Enter a string array to convert it to a string to get the string length. Analysis: The program exists in line 18th fault fault not triggered: 3.2 trigger fault, but cannot trigger error Construction Example: The mean value of a subtraction result of two numbers trigger fault, error not triggered: 3.3 trigger error, but cannot produce failure Construction Example: Three integers are added and subtracted, the sum of the results of the output plus and minus triggers the error, but does not produce failure:Add=0;errordel=2;error 4. SummaryThrough this program, the software in the fault,error,failure has a deeper understanding and understanding;
