What type of error is caused by bad syntax in a program?

The type of error caused by bad syntax in a program is known as a compile error. When a programmer writes code that does not conform to the rules of the programming language, the compiler is unable to translate the code into an executable format. This could be due to mistakes like missing punctuation, incorrect keywords, or mismatched parentheses. As a result, the compiler generates error messages indicating the line numbers and nature of the syntax issues that need to be corrected before the program can be successfully compiled and run.

Compile errors are typically caught at the development stage, meaning the program won't run until these issues are resolved. This contrasts with other error types, which may occur during the program's execution or due to logical missteps in code logic.
