The eighth letter of the English alphabet, is classed among the consonants, and is formed with the mouth organs in the same position as that of the succeeding vowel. It is used with certain consonants to form digraphs representing sounds which are not found in the alphabet, as sh, th, th, as in shall, thing, thine (for zh see 274); also, to modify the sounds of some other letters, as when placed after c and p, with the former of which it represents a compound sound like that of tsh, as in charm (written also tch as in catch), with the latter, the sound of f, as in phase, phantom. In some words, mostly derived or introduced from foreign languages, h following c and g indicates that those consonants have the hard sound before e, i, and y, as in chemistry, chiromancy, chyle, Ghent, Ghibelline, etc.; in some others, ch has the sound of sh, as in chicane. See Guide to Pronunciation, 153, 179, 181-3, 237-8.

H stands for hydrogen, the first element on the periodic table.

Null indicates missing or unknown information in database fields.

H is the eighth letter of the English alphabet.

Null represents the absence of a value or a non-existent reference.

In physics, H can denote enthalpy or other specific variables.

Programmers need to check for null to avoid null reference errors.

H commonly abbreviates hours.

Null is used to represent missing data in SQL databases.

No, null signifies no value, while zero is a numerical value.

Most modern programming languages support null, but usage may vary.

Null requires careful handling to prevent runtime errors in applications.

No, null values cannot participate in arithmetic operations.

H often represents height in geometrical shapes and formulas.

H is the symbol for hydrogen, a crucial element in chemistry.

Null is not a type but a special value indicating the lack of a valid object or value.
