Note: This question paper contains two parts A and B. Part A is compulsory which carries 25 marks. Answer all questions in Part A. Part B consists of 5 Units. Answer any one full question from each unit. Each question carries 10 marks and may have a, b, c as sub questions.
Part A
Distinguish between variables and constants. Give example.
Answer
A variable is a named storage location in memory whose value can be modified during the execution of a program. In contrast, a constant is a fixed value that does not change throughout the program's lifecycle.
For example, in C, the declaration
Explain the difference between break, goto and continue statements.
Answer
The break, continue, and goto statements are used to alter the normal flow of program execution:
- break: Immediately terminates the innermost loop (for, while, do-while) or switch statement in which it appears. Control shifts to the first statement following the loop or switch block.
- continue: Skips the remaining statements in the current iteration of a loop and forces the next iteration to begin immediately. It does not terminate the loop.
- goto: An unconditional jump statement that transfers control directly to a labeled statement within the same function. It is generally discouraged in structured programming due to the risk of creating complex, unreadable code.
