我有很急的Ｃ程式問題　想問一下各位大大因為要考試了可是我不會寫　可以幫忙解答嗎已經問過很多同學可是大家都不會拜託了　謝謝題目如下： 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'. 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. 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. 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. 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. 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". 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 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 125.225.105.234
