算法导论难是因为里面有大量的数学证明,这学期教材就是这本书,有时候3,4页都是一个公式的证明,头都大了
String Manipulation These routines operate on null-terminated single-byte character, wide-character, and multibyte-character strings. Use the buffer-manipulation routines, described in Buffer Manipulation, to work with character arrays that do not end with a null character. String-Manipulation Routines Routine Use _mbscoll, _mbsicoll, _mbsncoll, _mbsnicoll Compare two multibyte-character strings using multibyte code page information (_mbsicoll and _mbsnicoll are case-insensitive) _mbsdec, _strdec, _wcsdec Move string pointer back one character _mbsinc, _strinc, _wcsinc Advance string pointer by one character _mbslen Get number of multibyte characters in multibyte-character string; dependent upon OEM code page _mbsnbcat Append, at most, first n bytes of one multibyte-character string to another _mbsnbcmp Compare first n bytes of two multibyte-character strings _mbsnbcnt Return number of multibyte-character bytes within supplied character count _mbsnbcpy Copy n bytes of string _mbsnbicmp Compare n bytes of two multibyte-character strings, ignoring case _mbsnbset Set first n bytes of multibyte-character string to specified character _mbsnccnt Return number of multibyte characters within supplied byte count _mbsnextc, _strnextc, _wcsnextc Find next character in string _mbsninc. _strninc, _wcsninc Advance string pointer by n characters _mbsspnp, _strspnp, _wcsspnp Return pointer to first character in given string that is not in another given string _mbstrlen Get number of multibyte characters in multibyte-character string; locale-dependent sprintf, _stprintf Write formatted data to a string strcat, wcscat, _mbscat Append one string to another strchr, wcschr, _mbschr Find first occurrence of specified character in string strcmp, wcscmp, _mbscmp Compare two strings strcoll, wcscoll, _stricoll, _wcsicoll, _strncoll, _wcsncoll, _strnicoll, _wcsnicoll Compare two strings using current locale code page information (_stricoll, _wcsicoll, _strnicoll, and _wcsnicoll are case-insensitive) strcpy, wcscpy, _mbscpy Copy one string to another strcspn, wcscspn, _mbscspn, Find first occurrence of character from specified character set in string _strdup, _wcsdup, _mbsdup Duplicate string strerror Map error number to message string _strerror Map user-defined error message to string strftime, wcsftime Format date-and-time string _stricmp, _wcsicmp, _mbsicmp Compare two strings without regard to case strlen, wcslen, _mbslen, _mbstrlen Find length of string _strlwr, _wcslwr, _mbslwr Convert string to lowercase strncat, wcsncat, _mbsncat Append characters of string strncmp, wcsncmp, _mbsncmp Compare characters of two strings strncpy, wcsncpy, _mbsncpy Copy characters of one string to another _strnicmp, _wcsnicmp, _mbsnicmp Compare characters of two strings without regard to case _strnset, _wcsnset, _mbsnset Set first n characters of string to specified character strpbrk, wcspbrk, _mbspbrk Find first occurrence of character from one string in another string strrchr, wcsrchr,_mbsrchr Find last occurrence of given character in string _strrev, _wcsrev,_mbsrev Reverse string _strset, _wcsset, _mbsset Set all characters of string to specified character strspn, wcsspn, _mbsspn Find first substring from one string in another string strstr, wcsstr, _mbsstr Find first occurrence of specified string in another string strtok, wcstok, _mbstok Find next token in string _strupr, _wcsupr, _mbsupr Convert string to uppercase strxfrm, wcsxfrm Transform string into collated form based on locale-specific information vsprintf, _vstprint Write formatted output using a pointer to a list of arguments 肯定有人说这些不是算法,是字符串处理函数。但我认为这些就是最常用的“算法”。
如果非要说 那就是排序吧
你写的程序实时性要求高不高? 处理的数据量大不大? 是单独的项目还是批量的产品(即你的程序会同时在大量地方同时运行)? 是否有成本和功耗要求? 如果这些要求都没有, 那确实算法没什么用.
