let c = b / a The code will fail to compile because a is an integer and b is a floating point value. In math class, no one ever cared about this. Why would a programming language force the programmer to write in the conversion when they will always write the same conversion every t...

Error rates in indexing using string index languages such as NEPHIS might be reduced at relatively low cost by having the indexer enter strings via a microcomputer system which could provide simple validation, and feedback in the form of graphic displays of concept links.Timothy...

The first char value character of the sequence is at index 0, the next at index 1, and so on, as for array indexing. If the char value specified by the index is a surrogate , the surrogate value is returned. Specified by: charAt in interface CharSequence Parameters: index - ...

This library provides generic functions for string manipulation, such as finding and extracting substrings, and pattern matching. When indexing a string in Lua, the first character is at position 1 (not at 0, as in C). Indices are allowed to be negative
