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"...
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...
In this C++ tutorial, we will proceed to show exactly how one can convert an entire C++ String to uppercase, using the toupper() function.
comdef.StringMatchFunc) []string // source at strutil/format.go func Title(s string) string func Lower(s string) string func Lowercase(s string) string func Upper(s string) string func Uppercase(s string) string func UpperWord(s string) string func LowerFirst(s string) string func ...
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: ...
函数string.dump 返回一个函数二进制形式的字符串,用法为 string.dump (function) function test() print("just a test") end print(string.dump(test)) 函数string.dump 实现了函数的序列化,函数可以很轻松的传递,并在其他作用域调用。函数 string.dump 出来 ...
Usestd::transform()andstd::toupper()to Convert String to Uppercase std::transformmethod is from the STL<algorithm>library, and it can apply the given function to a range. In this example, we utilize it to operate onstd::stringcharacters range and convert eachcharto uppercase letters using...
_textThe string to convert to uppercase letters. Return value A copy of the specified string that contains only lowercase letters. Remarks ThestrUprfunction is complementary to thestrLwrfunction. ThestrUprfunction uses theLCMapString()function in the Win32 API. ...
2. Using std::for_each functionIf the boost library is not available, try using the standard algorithm std::for_each, which applies a given function object to every character of the string. The function needs to convert a character to uppercase in-place, as shown below:...
