This means we need to be able to isolate the characters of a string so we can apply the toupper() or tolower() function. The way we do this is by referring to the string as an array. In our example of string
publicstringToLower(); 返回 String 一个小写字符串。 示例 以下示例将多个混合大小写字符串转换为小写。 C# usingSystem;publicclassToLowerTest{publicstaticvoidMain(){string[] info = {"Name","Title","Age","Location","Gender"}; Console.WriteLine("The initial values in the array are:");foreach...
string.upper(),string.lower()和string.title()方法是Python中的内置方法,用于将字符串格式化为特殊格式,例如大写,小写或小写。 1) string.upper() 1)string.upper() Method returns uppercase string (where all characters of the string are in uppercase). 方法返回大写字符串(其中字符串的所有字符均为大写...
Console.WriteLine("Comparing '{0}' and '{1}':", stringUpper, stringLower); // Compare the uppercased strings; the result is true. Console.WriteLine("The Strings are equal when capitalized? {0}", String.Compare(stringUpper.ToUpper(), stringLower.ToUpper()) == 0 ? "true" : "false"...
In this program, we will learn how to implement our ownstrlwr()andstrupr()function in C language? Implementing strlwr() and strupr() functions in C This program will read a string from the user (string can be read using spaces too), and convert the string into lowercase and uppercase wi...
TOLOWER: This function is used to convert English characters in a string into lowercase characters. TOUPPER: This function is used to convert English characters in a string into uppercase characters. INITCAP: This function is used to convert the first letter of each word in English in a st...
语法BI_LOWER(string)参数说明string:需要全部转化为小写的字符串。定义 以全小写字符返回 string。输出 字符串 示例BI_UPPER('Hello World')='hello world' BI_LTRIM BI_LTRIM用于移除字符串的前置空格。语法 BI_LTRIM(string)参数... CONCAT_WS 返回将参数中的所有字符串或ARRAY数组中的元素按照指定的分隔符...
4). string.upper(s) 和lower相反,将小写转换为大写; 5). string.sub(s,i,j) 提取字符串s的第i个到第j个字符。Lua中,第一个字符的索引值为1,最后一个为-1,以此类推,如: --输出hello world 6). string.format(s,...) 返回格式化后的字符串,其格式化规则等同于C语言中printf函数,如: ...
