Y The figures in the margin indicate Full Marks, Vv Assume suitable data if necessary. 1. Define computer program. Write an algorithm and draw a flowchart to calculate the HCF of two numbers entered by the user. [Hint: HCF is a number that divides both the numbers exactly. [l+4] 2. Why do we need type casting in C? Explain Header files & Library functions in C with an example [2+3] 3. Define Operator in C. Differentiate between pre and post-increment operators in C with proper examples. [1+3] 4. How formatted outputs are different from unformatted outputs [3] 5.a) Differentiate between counter-controlled & sentinel-controlled loops in C. Write a program in C to display the Armstrong numbers between given ranges P and Q. [Hint: An Armstrong number is a number that is equal to the sum of digits raised to the power total number of digits in the number, e.g. 1634 = 14+64434+44 = 1+1296+81+256 = 1634] [2+5] b) Display the following pattern using the concept of nested loop in C.
