Consider line number 3 of the following C- program. 

C

int main ( ) {                   /* Line 1 */
  int I, N;                      /* Line 2 */
  fro (I = 0, I < N, I++);       /* Line 3 */
}

Identify the compiler\’s response about this line while creating the object-module

(A)

No compilation error

(B)

Only a lexical error

(C)

Only syntactic errors

(D)

Both lexical and syntactic errors

Answer: (D)

Explanation:

Lexical errors refer to errors related to the lexemes or tokens in the program, such as misspelled keywords or identifiers that are not recognized by the language. Here, “fro” instead of “for”.
Syntactic errors occur when the code violates the grammar or syntax rules of the programming language. Here, inside  for loop there is coma instead of semicolomn
