String-valued functions return NULL if the length of the result would be greater than the value of the max_allowed_packet system variable. For functions that operate on string positions, the first position is numbered 1.
1,ASCII(str)-Returns the numeric value of the leftmost character of the string str. Returns 0 if str is the empty string. Returns NULL if str is NULL. ASCII() works for characters with numeric values from 0 to 255.1. SELECT ASCII('2′);
2,BIN(N)-Returns a string representation of the binary value of N, where N is a longlong (BIGINT) number. SELECT BIN(12);
3,BIT_LENGTH(str)-Returns the length of the string str in bits.SELECT BIT_LENGTH('text');
4,CHAR(N,…)-CHAR() interprets the arguments as integers and returns a string consisting of the characters given by the code values of those integers. NULL values are skipped.1.SELECT CHAR(77,121,83,81,'76′);SELECT INSERT('Quadratic', 3, 4, 'What');
5,INSERT(str,pos,len,newstr)-Returns the string str, with the substring beginning at position pos and len characters long replaced by the string newstr.

How do you use the strtok function?
strtok sequentially truncate string if delimiter is found. If string is not NULL, the function scans string for the first occurrence of any character included in delimiters. If it is found, the function overwrites the delimiter in string by a null-character and returns a pointer to the token, i.e. the part of the scanned string previous to the delimiter. After a first call to strtok, the function may be called with NULL as string parameter, and it will follow by where the last call to strtok found a delimiter. delimiters may vary from a call to another. Parameters. string Null-terminated string to scan. separator Null-terminated string containing the separators. Return Value. A pointer to the last token found in string. NULL is returned when there are no more tokens to be found. Portability. Defined in ANSI-C.

Is there is any function or class in Java to check inputed string is valid char sequence and no numbers or any special char are there?
You should probably use regular expressions. For example, the following will check that the String s has only English (Latin) characters in it:boolean hasOnlyLatin = s.matches("^[a-zA-Z]*$");Learning to use regular expressions is scary at first, but worthwhile. See the related links for some information about regular expressions in Java.

How are the unrecognized character within the control string interpreted in printf function?
In the printf function in C, unrecognized characters within the format string are treated as literal characters. This means that any character that doesn't match a format specifier (like %d, %f, etc.) will be printed as-is in the output. For example, if the format string is "Hello %d!" and the integer value is 5, the output will be Hello 5!. Characters that are not part of a format specifier will simply appear in the output without any special formatting.
