Question

Consider Line 3 of the following C program:

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

Identify the compiler's response about Line 3 while creating the object module.

Accepted Answer

Correct answer: C — Correct answer: Only syntactic errors Lexical analysis: fro is a valid identifier token, and the symbols such as (, ,, ++, and ) are valid tokens. So this is not a lexical error. Intended syntax analysis: In this compiler-design/PYQ framing, the line is treated as a malformed for statement: fro is not the for keyword, and the loop header uses commas where semicolons are expected. Hence the intended compiler response is syntax errors. Clarification: Some C-language discussions treat fro(...) as a possible function-call expression in an older C dialect. That is a different interpretation from the intended answer key for this item.
