    Sharda Singh
    This document provides an answer sheet for an Information Technology exam with 3 programming questions worth a total of 45 marks. The first question is worth 15 marks and involves tracing an algorithm through a table and identifying the alternative operator to DIV. The second question is worth 10 marks and covers Pascal symbols like ;, {, :=, and . as well as identifying a syntax error and examples of loops, assignments, declarations, and conditions. The third question is worth 15 marks and involves working with arrays - identifying size, indexing letters, writing values, and searching/modifying arrays with FOR loops. The final question is worth 5 marks and covers an algorithm that prints a prompt, reads a value, and
