Invalid class string endnote word 20136/24/2023 Note that you can add and append C-style strings as well as string objects to a string object.Ĭout > operator to read a string object and cout with the > operator to display a string object using the same syntax you use with a C-style string. Str1 += str2 // add str2 to the end of str1 Str3 = str1 + str2 // assign str3 the joined strings You can use the + operator to add two string objects together and the += operator to tack on a string to the end of an existing string object.Ĭontinuing with the preceding code, we have the following possibilities: The string class simplifies combining strings. Str1 = str2 // VALID, object assignment ok But you can assign one string object to another:Ĭhar charr1 // create an empty arrayĬhar charr2 = “jaguar” // create an initialized arrayĬharr1 = charr2 // INVALID, no array assignment For example, you can’t simply assign one array to another. The string class makes some operations simpler than is the case for arrays. This makes using a string object both more convenient and safer than using an array.Ĭonceptually, one thinks of an array of char as a collection of char storage units used to store a string but of a string class variable as a single entity representing the string. String str2 = “panther” // create an initialized stringĬout > str1 // str1 resized to fit input String str1 // create an empty string object
