string toupper

Today, we need to implement a function to convert lower-case letters to upper-case letters. Because the input parameter is a string class in SL, the first idea is to use the Transform Algorithm to implement this function, but an error is returned.

ToLower convert uppercase to lowercase.Non-alphabetic characters do not make processing.This function is a bit special. He handles the characters rather than the strings.The so-called inability to handle strings does not mean that he cannot handle

String comparisons (ignoring case), which we will generally write as str1. ToUpper () = = str2. ToUpper () or str1. ToLower () = = str2. ToLower () This will be relatively inefficient, especially in cycles, which are slow to run as compared to
