[Solved] C# help declaring variable i initialize it to

Yes, the output is correct: // This line increments the variable then prints its value. Console.WriteLine(“{0}”, ++ Cash); // This prints the value of the (incremented variable) Console.WriteLine(“{0}”, Cash); // The prints the value of the variable *then* increments its value Console.WriteLine(“{0}”, Cash ++); 1 solved C# help declaring variable i initialize it to

[Solved] Does printf alter variables?

The output will be 1. Your expression ++x will be x = x+1; In both the printf() you get 1 So the value of x is modified with the pre-increment operator here and in printf() in the second line prints the new value of x which is 1 printf() just prints the value of x … Read more

[Solved] Why 2 and -2 instead of 1 and -1? [closed]

You need to understand the concepts of post increment(decrement) and pre increment(decrement). Post increment cout << x++<<endl; You can understand this line as “Return the value of x” + “increment the value of x”. I.e The return value is before the increment. So return 0 and increase the value of x to 1. Pre increment … Read more

[Solved] Long condition C++ [closed]

I do not know whether this solution is more efficient, but maybe it is more readable and easier to code: #include <iostream> #include <cstdlib> int main() { const int magicNumber = 32640; const int maxOffset = 1920; int n; std::cin >> n; int y = 20; const std::div_t divresult = std::div(n, magicNumber); if (divresult.rem > … Read more

[Solved] Java and incrementing strings

You can’t apply the ++ operator to a string, but you can implement this logic yourself. I’d go over the string from its end and handle each character individually until I hit a character that can just be incremented simply: public static String increment(String s) { StringBuilder sb = new StringBuilder(s); boolean done = false; … Read more

[Solved] Alphanumeric increment algorithm in JAVA [closed]

Here’s 3 solutions: the first two are somewhat arithmetic incrementations while the third is more a character manipulations. The 3 implementations all pass the same unit tests: assertEquals(“1DDA01A”, MyClass.increment(“1DDA00Z”)); assertEquals(“1A9AV00”, MyClass.increment(“1A9AU99”)); assertEquals(“AFH00”, MyClass.increment(“AFG99”)); assertEquals(“A2GF24”, MyClass.increment(“A2GF23”)); assertEquals(“ABAA0000”, MyClass.increment(“AAZZ9999”)); assertEquals(“11AB0A”, MyClass.increment(“11AA9Z”)); First: public static String increment(String number) { Pattern compile = Pattern.compile(“^(.*?)([9Z]*)$”); Matcher matcher = compile.matcher(number); String … Read more
