A logical error is when a program does not behave as intended, but does not crash. An example is that nothing happens when a button in a graphical user interface is clicke

unusually, due to errors in the compiler itself. A compilation error message often helps programmers debugging the source code for possible https://en.wikipedia.org/wiki/Compilation_error errors. Contents 1 Examples 1.1 Common C++ compilation errors 1.2 Internal https://www.youtube.com/watch?v=LyuqCLil-4Y Compiler Errors 2 References Examples[edit] Common C++ compilation errors[edit] Undeclared identifier, e.g.: doy.cpp: In function `int main()': doy.cpp:25: `DayOfYear' undeclared (first use this function)[1] This means that the variable "DayOfYear" is trying to be used before being declared. Common function undeclared, e.g.: xyz.cpp: In function `int main()': error handling xyz.cpp:6: `cout' undeclared (first use this function)[1] This means that the programmer most likely forgot to include iostream. Parse error, e.g.: somefile.cpp:24: parse error before `something'[2] This could mean that a semi-colon is missing at the end of the previous statement. Internal Compiler Errors[edit] An internal compiler error (commonly abbreviated as ICE) is an error that occurs not due error handling in to erroneous source code but rather due to a bug in the compiler itself. They can sometimes be worked around by making small, insignificant changes to the source code around the line indicated by the error (if such an line is indicated at all), but sometimes larger changes must be made such as refactoring the code to avoid certain constructs or using a different compiler or different version of the compiler. Example of an internal compiler error: somefile.c:1001: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See

Published on Aug 23, 2013CompilersBy Alex AikenThis course will discuss the major ideas used today in the implementation of programming language compilers, including lexical analysis, parsing, syntax-directed translation, abstract syntax trees, types and type checking, intermediate languages, dataflow analysis, program optimization, code generation, and runtime systems. As a result, you will learn how a program written in a high-level language designed for humans is systematically translated into a program written in low-level assembly more suited to machines. Along the way we will also touch on how programming languages are designed, programming language semantics, and why there are so many different kinds of programming languages.Why Study Compilers?Everything that computers do is the result of some program, and all of the millions of programs in the world are written in one of the many thousands of programming languages that have been developed over the last 60 years. Designing and implementing a programming language turns out to be difficult; some of the best minds in computer science have thought about the problems involved and contributed beautiful and deep results.
