The set of functions and their names varies depending on the computer programming language. The most basic example of a string function is the string length function – the function that returns the length of a string (not counting any terminator characters or any of the string's internal structural information) and does not modify the string.
sizeof is a unary operator in the programming languages C and C++.It generates the storage size of an expression or a data type, measured in the number of char-sized units.. Consequently, the construct sizeof (char) is guaranteed to be
In JavaScript, the empty string (""), null, undefined, NaN, +0, −0 and false [28] are sometimes called falsy (of which the complement is truthy) to distinguish between strictly type-checked and coerced Booleans (see also: JavaScript syntax#Type conversion). [29] As opposed to Python, empty containers (Arrays, Maps, Sets) are considered truthy.

The distance from (x 0, y 0) to this line is measured along a vertical line segment of length |y 0 - (-c/b)| = |by 0 + c| / |b| in accordance with the formula. Similarly, for vertical lines ( b = 0) the distance between the same point and the line is | ax 0 + c | / | a |, as measured along a horizontal line segment.
