Furthermore, the use of macros in C can also provide a way to convert variable names to strings. By defining a macro that takes a variable name asan argument and uses the `` operator, it is possible to create a
有些clang-tidy检查提供了特定的检查方式来消除诊断,比如bugpron-use-after-move后的变量可以通过在变量被移出后重新初始化来消除警告,bugpron-string-integer-assignment可以通过显式转换将整数转换为char来抑制,可读性-implicit-bool-conversion也可以通过显式转换来抑制等等。 如果特定的压制机制对某一警告不适用,或者...

String类包含用于连接两个字符串的方法: string1.concat (string2相等); 这将返回一个新的字符串,它是string1,末尾添加了string2。 字符串通常与+运算符连接,如in“Hello”+“world”+“! 需要注意的是:当使用字符串的时候,如果超过行大小,则需要+连接比如如下: String quote = "Now is the time for all...
Declare an integer variable and a character array (string) to store the converted value: int num; char str[20]; The int num will store the integer value we want to convert, and str will store the resulting string. Ensure that str has enough space to hold the converted string. Use snp...
