Difference Between Syntax and Semantics

Computer ProgrammingProgrammingMiscellaneous

In this post, we will understand the difference between syntax and semantics.

Syntax

  • It defines the rules and regulations that helps write any statement in any programming language.

  • It doesn’t have any relationship with the meaning of the statement.

  • It is associated with the grammar and structure of the programming language.

  • A line of code is syntactically valid and correct if it follows all the rules of syntax.

  • It does not have to do anything with the meaning of the statement.

  • Syntax errors are encountered after the program has been executed.

  • Some examples include: missing semicolons in C++, undeclared variables in Java

  • Such errors are easy to catch.

Semantics

  • It refers to the meaning of the associated line of code in a programming language.

  • The semantic errors are handled during runtime of the program execution.

  • It tells about the meaning, and helps interpret what function the line of code/program is performing.

  • Semantic errors are encountered at runtime.

  • They are encountered at runtime.

  • Even when a statement has correct syntax, it wouldn’t do the function that was intended for it to do.

  • Such errors are difficult to catch.
