Arduino内置教程-字符串

字符串

• Character Analysis：使用operators来识别对应的特征类型。
• String Addition Operator：用不同方法把字符串加到一起。
• String Append Operator：用+=运算符和concat()方法来添加东西到字符串里。
• String Case Changes：改变字符串的状态。
• String Characters：在字符串里获得或设置一个指定的字符的值
• String Comparison Operators：按字母排列顺序地比较字符串
• String Constructors：初始化字符串对象
• String Index Of：寻找在字符串里字符的第一个或最后一个的状态
• String Length & String Length Trim：获得和修剪字符串的长度
• String Replace：替换字符串里的个别字符
• String Start With Ends With：检查一个给定的字符或子串（substrings）的开始或结尾
• StringSubstring - 在给定的字符串里寻找"phrases"
• StringToInt - 允许你把字符串转换成整数数字

Character Analysis: Use the operators to recognise the type of character we are dealing with. String Addition Operator: Add strings together in a variety of ways. String Append Operator: Use the += operator and the concat() method to append things to Strings. String Case Changes: Change the case of a string. String Characters: Get/set the value of a specific character in a string. String Comparison Operators: Compare strings alphabetically. String Constructors: Initialize string objects. String Index Of: Look for the first/last instance of a character in a string. String Length & String Length Trim: Get and trim the length of a string. String Replace: Replace individual characters in a string. String Start With Ends With: Check which characters/substrings a given string starts or ends with. String Substring: Look for "phrases" within a given string. String To Int: Allows you to convert a String to an integer number.
