[Solved] Java incrementing every character in a string by a large amount?

by

[ad_1] First I’m going to remove all of the I/O (except for outputting the result), get rid of the decryption piece for brevity, and write encrypt(String) and encrypt(char) as pure functions. public class EncryptionMain { public static void main(String args[]){ System.out.println(encrypt(“Hello”)); } static String encrypt(String plaintext) { StringBuilder ciphertext = new StringBuilder(plaintext); for (int i … Read more

[Solved] Why does assignment to parameter not change object?

by

[ad_1] The observed behavior has nothing to do with Value types vs Reference types – it has to do with the Evaluation of Strategy (or “calling conventions”) when invoking a method. Without ref/out, C# is always Call by Value1, which means re-assignments to parameters do not affect the caller bindings. As such, the re-assignment to … Read more

[Solved] Cannot use array with GCC

by

[ad_1] Because <array> got indirectly included from somewhere and you made the mistake of using namespace std, “array” in ErrorMessage refers to that name in the std namespace. That is a class template, not a type – hence the error message. Outside of value, its array is called value::array. (The typedef value::array array in value … Read more
