Doesn't matter if it has addressed my example or not, what really matters is that I got the answer clearly. That guy explained it in a simple way that can be easy to understand to a naive programmer like me. Did you read the stackoverflow.

This is true relative to compile-time errors but runtime errors are much easier to debug than a program that produces invalid results silently, which is typically the most difficult class of bugs to identify and resolve. If you are unable to compile your code, that is a compiler error. If you compile and run your code, but then it fails during execution, that is runtime.
James Montagne James Montagne In your example, discountVariable is of declared type DiscountSale and saleVariable is of another type. If you put the cast in place DiscountSale , this tells the compiler that it's okay. It then breaks when you run it because saleVariable is not actually of the DiscountSale type. I would be much happier if the answer actually addressed the specific example offered by the OP, however. Community Bot 1 1 1 silver badge.

Compile time errors are errors of syntax and semantics. Hadi Hadi 7 7 silver badges 18 18 bronze badges. Kasun Siyambalapitiya 3, 6 6 gold badges 30 30 silver badges 53 53 bronze badges. These are the errors which are not detected by the compiler and produce wrong results.
They prevent the code from running as it detects some syntax errors. They prevent the code from complete execution. It includes syntax errors such as missing of semicolon ; , misspelling of keywords and identifiers etc.
It includes errors such as dividing a number by zero, finding square root of a negative number etc. Skip to content. The compiler will not allow to run the program until all the errors are removed from the program. When all the errors are removed from the program, then the compiler will generate the executable file. When the programmer does not follow the syntax of any programming language, then the compiler will throw the syntax error.
The above declaration generates the compile-time error as in C, every statement ends with the semicolon, but we put a colon : at the end of the statement.
The above statement throws a compile-time errors. In the above statement, we are assigning the value of 'c' to the summation of 'a' and 'b' which is not possible in C programming language as it can contain only one variable on the left of the assignment operator while right of the assignment operator can contain more than one variable.
The runtime errors are the errors that occur during the execution and after compilation. The examples of runtime errors are division by zero, etc. These errors are not easy to detect as the compiler does not point to these errors. In the above code, we have tried to print the value of 'a', but it throws an error. We put the colon at the end of the statement instead of a semicolon, so this code generates a compile-time error.

The terms "runtime" and "compile time" are often used by programmers to refer to different types of errors too.
Compile-time checking occurs during the compile time. Compile time errors are error occurred due to typing mistake, if we do not follow the proper syntax and semantics of any programming language then compile time errors are thrown by the compiler.
They wont let your program to execute a single line until you remove all the syntax errors or until you debug the compile time errors. The following are usual compile time errors:. Run-time type checking happens during run time of programs. Runtime errors are the errors that are generated when the program is in running state. These types of errors will cause your program to behave unexpectedly or may even kill your program. They are often referred as Exceptions.
The following are some usual runtime errors:. Home C VB. Runtime vs Compile time Runtime and compile time are programming terms that refer to different stages of software program development. The following are usual compile time errors: Syntax errors Typechecking errors Compiler crashes Rarely Run-time type checking happens during run time of programs.
