Use the Custom Function to Convert String to Lowercase in C This article will demonstrate multiple methods about how to convert string to lowercase in C. Use thetolowerFunction to Convert String to Lowercase in C Thetolowerfunction is part of the C standard library defined in the<ctype.h>hea...
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 sport = "Basketball";...
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: --输出pi ...
函数string.lower 用于把字符串 s 里的字母转为小写,用法 string.lower (s) 例子: print(string.lower("AbCdEfG")) 7)string.upper 函数string.upper 用于把字符串 s 里的字母转为大写,用法 string.upper (s) 例子: print(string.upper("AbCdEfG")) ...
--string.lower(s) --将s中的大写字母转换成小写(string.upper将小写转换成大写).如果你想不关心大小写对一个数组进行排序的话,你可以这样: --string.upper(s) --将s中的小写字母转换成大写 --string.sub(s,i,j) --函数截取字符串s的从第i个字符到第j个字符之间的串.Lua中,字符串的第一个字符索引...
