Here’s a thought problem: Did you give it a try? Numbers Around the World . It's about offsets. It put a fair burden of the workload on the programmer, where other languages had the compiler and the machine do the heavy lifting. I told you above that Animals and Birds also can count. Words which meant ‘void,’ ‘sky,’ ‘space’ all represented nothingness or zero. In my experience indexes going from 1 to n is more popular than indexes going from 0 to n-1 in mathematics.

Why do most language's definition of substring allow substring(“abc”, 3) => “”.

It is an essential element in humanity's most basic counting machine, the Abacus. Counting units from zero too brings a few consistency advantages, notably with half-open intervals and (multi-dimensional) arrays. u/gratedcheeseinoven. Each time a sheep passes, place a stone in a pile. Assembly languages typically started from 0 because arrays are traditionally defined in terms of a starting address and an offset from the starting address. Yes. ... so they invented different clay tokens to represent different numbers of each specific commodity, and by 4000 BC strung the tokens like beads on a string. Basically the same, you don't really need zero for counting. Why was the percent sign (%) chosen as the format specifier for the printf family of functions?

The innovative Italians of the Renaissance (14th through 16th century) are widely acknowledged to be the fathers of modern accounting. Possible solution one:Obtain a large supply of stones. Is the intensity of light ONLY dependent on the number of photons, and nothing else? The convention spread because programmers started working in very low-level languages where memory addresses were directly manipulated and in most cases building up from there, maintaining the same convention at each step so that they wouldn't have to relearn or be prone to mistakes when switching between conventions. One of the first tools for counting invented, the abacus was invented around 1200 B.C. Which they had. Why put a big rock into orbit around Ceres? C++ got it from C because of the requirement that C++ be backward-compatible (some might say bug-compatible) with C. Java got it from C. Languages developed by C programmers with no significant exposure to anything else copied C, because they either wanted to be popular with other C programmers or they didn't know any other way to do it. Then in 1890 Japanese mathematicians worked on it and created ‘integers’. Algebra . all?) The Indian scholar Pingala used binary numbers and was the first to use the Sanskrit word ‘sunya’ for zero. Mathematics (from Greek: μάθημα, máthēma, 'knowledge, study, learning') includes the study of such topics as quantity (number theory), structure (), space (), and change (mathematical analysis). For example, Roman Numerals: I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII, XIII, XIV, XV.. and so on. WBT's explanation also makes sense as to why one would start with zero based on memory addresses. I thought, perhaps, it had to do with all being rooted in binary.

Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. So, for instance in K&R's C, when discussing array indexes, K or R matter-of-factly explains, "Array subscripts always start at zero in C..." (p. 22) Later, in discussing a function to process character arrays, "... a more useful design would be to return the length of the line, or zero if end of file is encountered. Then he thought of inventing a number system of adding and multiplication. What is the origin/meaning of the name 'NHibernate'? You need a symbol for zero if your number system includes the concept of "place value"; like how we use the same numeral "3" to mean 3 units, or 3 tens (30), or 3 hundreds (300) with zeroes occupying the other places to make it clear.
