strlen
常见例句
- The strlen() function returns the length of a string.
函數的作用是:返廻字符串長度。 - We can use this fact to write another version of strlen, which computes the length of a string.
如果要更詳細的了解,建議還是把這章細讀一遍。 - When we call strlen, it returns the number of characters in a zero-terminated array of single-byte characters.
許多年來,許多人一直將字符串作爲一系列單字節字符來進行編碼,竝在結尾処加上0. - The strlen() call was there only to make sure the value is actually accessed....
如果在聲明中用表達式的結果對其賦值會導致解析錯誤。 - BTW: if you want to call recv() with the maximal length of return_msg, please use sizeof(return_msg) instead of strlen(return_msg).
但是就是不明白爲什麽如果接受的長度大於了實際返廻的長度就可能出現我上述的那種情況呢(好像不是所有的時候都那樣)! - The standard library function strlen(s) returns the length of its character string argument s,excluding the terminal ‘\0’.
內部表示字符串時,要用一個空字符‘\\0’來結尾,所以實際存儲該字串的存儲單元比括在雙引號中的字符多一個。) 返回 strlen
