Syntax: It refers to the rules and regulations for writing any statement in a programming language like C/C++. It does not have to do anything with the meaning of the statement. A statement is syntactically valid if it follows all the rules. It is related to the grammar and structure of the language. Semantics:

GFG! Tabular Difference between Syntax and Semantic Error: It refers to the rules of any statement in the programming language. It is referred to as a syntax error. It is generally encountered at the compile time. It occurs when a statement that is not valid according to the grammar of the programming language.

Semantics follow directly from syntax. Syntax refers to the structure/form of the code that a specific programming language specifies but Semantics deal with the meaning assigned to the symbols, characters and words. Usually, syntax and semantics analysis of the code is done in the 'frontend' part of the compiler.

T he semantics of a language, in turn, indicates if a sentence has a concrete representation for those who hear or read it. Programming languages pay special attention to their lexicon, syntax, and semantics. It occurs due to the necessity of being exact (without ambiguity) in expressing the instructions for a computer.
