If our program has no compile-time errors and no link-time errors, it’ll run. This is where the fun really starts.
Errors which happen during program execution (run-time) after successful compilation are called run-time errors. Run-time errors occur when a program with no compile-time errors and link-time errors asks the computer to do something that the computer is unable to reliably do.
It happens after we give the ./ execute command:
Some common run-time errors:
- Division by zero also known as division error. These types of error are hard to find as the compiler doesn’t point to the line at which the error occurs.
- Trying to open a file that doesn’t exist
There is no way for the compiler to know about these kinds of errors when the program is compiled.
Here’s an example of a run-time error message:
Instructions
There’s a run-time error in ratio.cpp.
This program is supposed to find the ratio of a table’s dimensions, which is supposed to be 20 x 30.
