strchr strrchr wcsrchr _tcsrchr 字符串操作

1）

char *strchr( const char*string,intc);
wchar_t*wcschr( const wchar_t*string,wchar_tc);
Find a character in a string. 查找一个字符串中首次出现的指定字符。

Return Value:Each of these functions returns a pointer to the first occurrence ofcinstring(address), or NULL ifcis not found.

（2）
char *strrchr( const char*string, intc);
char *wcsrchr( const wchar_t*string,intc);

Scan a string for the last occurrence of a character.:查找一个字符串中最后出现的指定字符。

Return Value:Each of these functions returns a pointer to the last occurrence ofcinstring(address), or NULL ifcis not found.
找出字符串中最后一个出现查找字符的地址，然后将该字符出现的地址返回。
