(Common to All Branches)

Time: 3 hours Max Marks: 75

Answer any Five Questions

All Questions Carry Equal Marks

1. a) What is an algorithm? Write an algorithm to arrange three integer elements in ascendingorder.

b) What are the programming development steps? Explain. 8m + 7m

(a) Algorithm:

Refer Section 1.8 & 1.9

Algorithm to arrange three integer elements in ascending order:

Step 1: Start

Step 2 : Accept three numbers from user (a, b, c)

Step 3 : If a < b then goto step 4 else goto step 8

Step 4 : if a < c then goto step 5 else goto step 7

Step 5 : If b < c then goto step 9 else goto step 6

Step 6 : Interchange b and c and goto step 9

Step 7 : Interchange a and c and goto step 3

Step 8 : Interchange a and b and goto step 3

Step 9 : Display Ascending order

Step 10 : Display a, b, c

Step 11 : Stop

(b) Refer Section 1.22
