What are considered common programming errors?
Back in the old days, long before our understanding of coding became what it is today, programming errors could be truly disastrous. Luckily for us all, modern coding approaches and debugging systems make it a lot easier to fix these mistakes.
The 7 most commonly encountered programming errors are:
1. Runtime errors
These bugs occur when the code “won’t play nice” with another computer, even if it worked perfectly fine on the developer’s own computer. These errors are especially frustrating because they directly impact the end user and make the application appear unreliable or even completely broken.
2. Logic errors
These errors can be extremely frustrating to deal with because nothing is inherently wrong with the code: the developer just didn’t program the computer to do the correct thing. In fact, a logic error caused by miscalculations between American and English units caused NASA to lose a spacecraft in 1999.
3. Compilation errors
Compilation is the process of converting a high-level coding language into a lower-level language that can be better understood by the computer. Compilation errors occur when the compiler isn’t able to properly transform the high-level code into the lower-level one. This prevents the software from being launched or tested.
4. Syntax errors
Computer languages have their own specialized grammar rules. When these rules aren’t followed (for example, the developer omits the parentheses while writing code), a syntax error prevents the application from running.
5. Interface errors
These bugs typically happen when the inputs the software receives do not conform to the accepted standards. When handled incorrectly, these errors can look like errors on your side even when they’re on the caller’s side, and vice versa.
6. Resource errors
Sometimes, a program can force the computer it’s running on to attempt to allocate more resources (processor power, random access memory, disk space, etc.) than it has. This results in the program becoming bugged or even causes the entire system to crash.
7. Arithmetic errors
These errors are just like logic errors, but with mathematics. For example, a division equation may require the computer to divide by zero. Since this is mathematically impossible, it results in an error that prevents the software from working correctly.
