The result of a quiz competition is to be prepared as follows:
The quiz has five questions with four multiple choices (A, B, C, D), with each question carrying 1 mark for the correct answer. Design a program to accept the number of participants N such that N must be greater than 3 and less than 11. Create a double-dimensional array of size (N * 5) to store the answers of each participant row-wise. Calculate the marks for each participant by matching the correct answer stored in a single-dimensional array of size 5. Display the scores for each participant and also the participants(s) having the highest score.
Example: If the value of N = 4, then the array would be:
Q1 | Q2 | Q3 | Q4 | Q5 | |
Participant 1 | A | B | B | C | A |
Participant 2 | D | A | D | C | B |
Participant 3 | A | A | B | A | C |
Participant 4 | D | C | C | A | B |
Key to the question: | D | C | C | A | B |
Note: Array entries are line fed (i.e. one entry per line)
Test your program for the following data and some random data.
Example 1:
INPUT:
N = 5
Participant 1 D A B C C
Participant 2 A A D C B
Participant 3 B A C D B
Participant 4 D A D C B
Participant 5 B C A D D
Key: B C D A A
OUTPUT:
Scores:
Participant 1 = 0
Participant 2 = 1
Participant 3 = 1
Participant 4 = 1
Participant 5 = 2
Highest Score: Participant 5
Example 2:
INPUT:
N = 4
Participant 1 A C C B D
Participant 2 B C A A C
Participant 3 B C B A A
Participant 4 C C D D B
Key: A C D B B
OUTPUT:
Scores:
Participant 1 = 3
Participant 2 = 1
Participant 3 = 1
Participant 4 = 3
Highest score:
Participant 1
Participant 4
Example 3:
INPUT:
N = 12
OUTPUT:
INPUT SIZE OUT OF RANGE.
