trya = notaFunction(5,6);catchwarning('Problem using function. Assigning a value of 0.'); a = 0;end Warning: Problem using function. Assigning a value of 0. By itself, the call tonotaFunctionresults in an error. If you usetryandcatch, this code catches any exception and repackages...
In the above C program, theENDTRYfunction is used for providing the closing part of the do-while block. Conclusion If a program encounters an exception due to a data or coding error while it is running, “try” and “catch” describe how to manage it. In atryblock of code, exceptions...
foreach (string input in inputs) { if(TimeSpan.TryParseExact(input, formats, culture, TimeSpanStyles.AssumeNegative, out interval)) Console.WriteLine("{0} --> {1:c}", input, interval); else Console.WriteLine("Unable to parse {0}", input); } } } // The example displays the followi...
