Which type of error occurs when there are missing semicolons at the end of statements?

Omitting the semicolon at the end of a statement is a syntax error. The computer issues an error message when it cannot recognize the statement. These messages can occur at the point of the error, or after it.

In some ways, semantic errors are the hardest to debug, because the interpreter provides no information about what is wrong. Only you know what the program is supposed to do. You will often wish that you could slow the program down to human speed, and with some debuggers you can.

A syntax error is an error in the source code of a program. A logic error (or logical error) is a ‘bug’ or mistake in a program’s source code that results in incorrect or unexpected behaviour. It is a type of runtime error that may simply produce the wrong output or may cause a program to crash while running.

Semantic errors are the most dangerous of the three types of errors, because in some cases they are not noticed by either the programmers or the users who use the program. However, programs often go for years with undetected semantic errors; no one realizes that the program has been producing incorrect results.

I understand that it is good syntax to use semicolons after all statements in Javascript, but does any one know why if/else statements do not require them after the curly braces? Basically, an if-else must be followed by either a statement or a group of statements.

Yes, forgetting a semicolon causes errors on the next line (in fact, gcc usually reports it on the line following the one missing a semicolon), but that isn’t a very strong cascading effect (most likely you will only get one error). a.cpp:4: error: expected `;’ before ‘printf’… Loading…

This generates a compilation error, as almost always the combined multi-line expression is invalid. The error is often not on the line where you omitted the semicolon but later, where the combined statement is ultimately invalid. If the compiler could figure out what you meant, then we wouldn’t need semicolons in the first place.

When an if statement requires several True conditions at the same time, we join those different conditions together with the and operator. Such a combined condition becomes False as soon as one condition tests False. Let’s look at some examples. So when we combine conditions with and, both have to be True at the same time.
