  2. Syntax error - Wikipedia

    en.wikipedia.org/wiki/Syntax_error

    Type errors (such as an attempt to apply the ++ increment operator to a Boolean variable in Java) and undeclared variable errors are sometimes considered to be syntax errors when they are detected at compile-time.

  3. Cut, copy, and paste - Wikipedia

    en.wikipedia.org/wiki/Cut,_copy,_and_paste

    The functions were mapped to key combinations using the ⌘ Command key as a special modifier, which is held down while also pressing X for cut, C for copy, or V for paste. These few keyboard shortcuts allow the user to perform all the basic editing operations, and the keys are clustered at the left end of the bottom row of the standard QWERTY ...

  4. Online analytical processing - Wikipedia

    en.wikipedia.org/wiki/Online_analytical_processing

    For example, the overall sum of a roll-up is just the sum of the sub-sums in each cell. Functions that can be decomposed in this way are called decomposable aggregation functions, and include COUNT, MAX, MIN, and SUM, which can be computed for each cell and then directly aggregated; these are known as self-decomposable aggregation functions.

  5. Troubleshooting - Wikipedia

    en.wikipedia.org/wiki/Troubleshooting

    Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system.It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again.

  6. Exception handling syntax - Wikipedia

    en.wikipedia.org/wiki/Exception_handling_syntax

    C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions. In any case, a possible way to implement exception handling in standard C is to use setjmp/longjmp functions:

  7. Compilation error - Wikipedia

    en.wikipedia.org/wiki/Compilation_error

    xyz.cpp: In function `int main()': xyz.cpp:6: `cout' undeclared (first use this function) [3] This means that the programmer most likely forgot to include iostream . Parse error, e.g.:

  8. Pentium FDIV bug - Wikipedia

    en.wikipedia.org/wiki/Pentium_FDIV_bug

    Various software patches were produced by manufacturers to work around the bug. One specific algorithm, outlined in a paper in IEEE Computational Science & Engineering, is to check for divisors that can trigger the access to the programmable logic array cells that erroneously contain zero, and if found, multiply both numerator and denominator by 15/16.

  9. Name mangling - Wikipedia

    32-bit compilers emit, respectively: _f _g@4 @h@4 In the stdcall and fastcall mangling schemes, the function is encoded as _name@X and @name@X respectively, where X is the number of bytes, in decimal, of the argument(s) in the parameter list (including those passed in registers, for fastcall).
