}

Example:

Char STR [] = "m y B eautiful C hin! ";

Char * s = trim (STR, 32 );

+ S 0x0030fd0f "mybeautifulchina! "Char *

2) Remove the specified character C from string S.

Static char * ltrim (char * s, char C)
{
While (* s! = 0 & * s = c) {s ++;} return S;

Char * s = ltrim (STR, 32 );

+ S 0x0028f804 "m y B eautiful C hin! "Char *

2) Remove the specified character C from string S.

Static char * rtrim (char * s, char C)
{
Char * P = s, * q = s; while (* P! = 0) {If (* P! = C) {q = P; q ++;} p ++;} If (Q! = S) * q = 0; return S;

}

Example:

Char STR [] = "m y B eautiful C hin! ";

Char * s = rtrim (STR, 32 );

+ S 0x002cf6fc "m y B eautiful C hin! "Char *

Char * s = rtrim (ltrim (STR, 32), 32 );
