半夜睡不著所以佛心一下 明天還要上班 Orz ※ 引述《Vxprincessx (^^)》之銘言： : 1. [清除記憶體]Write a function "void bzero(char*p, int n)" to set the n : contiguous bytes of memory starting from the pointer p to '\0'. #include <cstring> void bzero(char*p, int n) { memset(p, 0, n); } : 2. [設定記憶體]Write a function "void bset(char*p, int n, char x)" to set : n contiguous bytes of memory starting from the pointer p to the value of x. #include <cstring> void bset(char*p, int n, char x) { memset(p, x, n); } : 3. [反向字元搜尋]Write a function "int findlast(char *s, char c)" to : retur : the index position of the last occurrence of a specified char c within the : string s, and return -1 if not found, such as findlast("language",'a') : returns 5. #include <string> int findlast(char *s, char c) { std::string str(s); return str.rfind(c); } : 4. [八進位字串轉整數]Write a function "int otoi(char h[])" to convert an : octal string h to an integer, such as otoi("377") returns 255. #include <stdio.h> int otoi(char h[]) { int i; sscanf(h, "%o", &i); return i; } : 5. [十六進位字串轉整數]Write a function "int xtoi(char h[])" to convert a : hexadecimal string h to an integer, such as xtoi("3ff") returns 1023. #include <stdio.h> int xtoi(char h[]) { int i; sscanf(h, "%x", &i); return i; } : 6. [去兩邊空白]Write a function "void trim(char s[])" to remove the : rightm : and leftmost spaces of string s, such as trim(" ab c ") gets "ab c". #include <boost/algorithm/string.hpp void trim(char s[]) { boost::algorithm::trim(s); } : 希望有好心人幫幫我這可憐的學生　　 : 這科沒過就要延畢了 : 拜託各位大大幫幫忙 : 我會感激不盡　　謝謝 不客氣 你們老師應該會覺得你很厲害 都只要一行就寫完了 半夜寫程式要開燈 不然對視力不好喔 要是因為都用現成的函式被當掉別怪我喔 重修一遍對你可能比較好喔 科科 --
