What is compile time and run time?
One COMPUTATION is Compile time is when it happens when your program is compiling (comuted by the compiler) and is Runtime when it happens when your program is running. C++ is faster than Java and C# and one of the reasons for that is that most of the work is done at compile time, even when we are talking about generic programming
compile time error happens when there is some fault in arrangement of codes I.e. syntax or there is something missing in the code run time error happens when memory gets full so code can't run
