"run time" is the opposite of "compile time". It refers to the time when the program is actually running.
coz at the run time object is provided memory , that's why object is called run time entity .
Linkage time.
A run time error occurs when a compiled program executes, and during execution, the binary code attempts a task that is not permitted by the operating system or libraries. Divide by zero is an example of a run time error. When the executed program divides one variable by a second variable, and the second variable holds a value of zero, the run time library will issue a run time error. Since the compiler cannot predict the values held by the variables, it cannot prevent such an error from occurring, and so the run time library traps the run time error during program execution. . Some run time errors include: - divide by zero - no stack space - memory reference out of bounds - write protected file
I've had mine for over a year, I typically get between 30-40 minutes of run time.
Solar, wind and tidal are three sources of fuel/energy that will only run out at the end of time.
