Unfortunately, no programmer writes mistake-free code 100% of the time, so it is useful to learn how to debug your programs. Here, we will purposely place a bug in our code and then use feedback from the compiler error and TextPad to fix it.
return "Hello World!";Remove the semicolon from the end of the line.
HelloWorldBot.cs(11,25): error CS1002: ; expected Tool completed with exit code 1This is an error message telling you that the file on line 11, column 25 in HelloWorldBot.cs, a semicolon is expected.
Sometimes compiler error messages can be very cryptic, unlike this straightforward one. Interpreting error messages is a skill gained with experience. Also, the compiler is also not always correct about where the error occurs; the error often occurs on the line before or after the mentioned line. Also, it is not uncommon to have multiple error messages on one compile. In these cases, it is usually best to try and fix the first error message, and then recompile to see if any of the others are corrected by the same change.Previous Next
