What is the maximum value support in CHAR data type in PHP?
0 to 255
The length can be any value from 0 to 255. When CHAR values are stored, they are right-padded with spaces to the specified length. When CHAR values are retrieved, trailing spaces are removed unless the PAD_CHAR_TO_FULL_LENGTH SQL mode is enabled. Values in VARCHAR columns are variable-length strings.
What is the value of CHAR data type?
The default value of Char is the character with a code point of 0.
What is the maximum length of a character data field?
65000 octets
CHAR is conceptually a fixed-length, blank-padded string. Trailing blanks (spaces) are removed on input, and are restored on output. The default length is 1, and the maximum length is 65000 octets (bytes).
What is the size of CHAR datatype *?
1 byte

What values can char hold?
A single char can hold an integer value from -127 to +127. ( An unsigned char can hold 0 to 255. ) Ascii characters fall in the range of 0 to 127.

What is the maximum size of character stored in field declared with text data?
TEXT is a string data type that can store up to 65,535 characters.
What is the maximum value an unsigned char data type can store?
A maximum value that can be stored in an unsigned char data type is typically 255, around 28 – 1 (but is compiler dependent). The maximum value that can be stored in an unsigned char is stored as a constant in the header file, whose value can be used as UCHAR _ MAX. A minimum value that can be stored in an unsigned char data type is 0.
What is the maximum length of A varchar character?
The default length is 1, and the maximum length is 65000 octets (bytes). VARCHAR is a variable-length character data type. The default length is 80, and the maximum length is 65000 octets. For string values longer than 65000, use Long Data Types.
What is the maximum value of INT in C++?
The limits for integer types in C and C++ are listed in the following table. Minimum value for a variable of type int.-2147483647 – 1: INT_MAX: Maximum value for a variable of type int. 2147483647: UINT_MAX: Maximum value for a variable of type unsigned int. 4294967295 (0xffffffff)
How much memory does Char take in C?
char The char type takes 1 byte of memory (8 bits) and allows expressing in the binary notation 2^8=256 values. The char type can contain both positive and negative values.
