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
