The last two lines should clue you in: one has y++ before the closing brace, and the other has it after. In the first, y will be incremented each time the loop runs, right before a=a+y is executed. In the second, y will be incremented after the loop ends.
str.replace(“\\D”, “”); will remove all non-digit characters from the string, then you can just parse it: Integer.parseInt(str);
Not likely to be your crash, but this code is terrible: if (fnameFile.is_open()) { while (fnameFile.eof() == false) { plFname.resize(numFnames); getline(fnameFile,line); numFnames += 1; } fnameFile.close(); } It doesn’t check for end of file correctly, because end of file happens during getline, not before. And the line variable goes nowhere. Try while (getline(fnameFile,line)) plFnames.push_back(line); fnameFile.close();
Use a try catch block. var serversToTry = new []{“Server1”, “Server2”}; foreach (var server in serversToTry) { try{ //connect to server return; //if you made it this far, connection succedded. } catch (Exception e) { //log e if you want } }
NSMutableDictionary *mdictionary = [NSMutableDictionary dictionary]; NSMutableArray *marray = [NSMutableArray array]; [mdictionary setObject:marray forKey:@”key”]; [mdictionary removeObjectForKey:@”key”];
There are some flaws in your code: you should prefer int.TryParse instead of Parse. An Exception should be an unexpected behavior, where you have to react in some way. A userinput is not unexpected, you know there’s a chance that the use inputs invalid data which you can/have to validate. When you use exceptions, you … Read more
if(condition): // some scripts here endif; Is same as if(condition) { // some scripts here } See http://php.net/manual/en/control-structures.alternative-syntax.php
See this here & here. i think it might be helpful in your case. EDIT: You can also use iRate (Steps).
Java is not a good platform for exploring this, and in fact I don’t know any high-level languages that are (not even C). The structure is so basic that the manipulation of it is built into the languages themselves, and they don’t really have constructs for implementing it (again). Try assembler, either a real assembler … Read more
In your commented line, % n=[0:10:100]; you create a vector with values from 0 to 100, with spacing 10, ie [0 10 20 30 40 50 60 70 80 90 100]. With your uncommented line, n=[0 3 5 10 50 100]; you have the values you specify. Since they’re not the same input, you won’t … Read more
