Question

2. (5 marks) Write an algorithm as a flow chart that reads in values for a series of numbers (so you will have to read in inside a loop, and test for EOF to end the loop). For each number, if it is the algorithm will print out "Positive". The algorithm should stop when five negative numbers have been found.

Answer 1

Algorithm:

1. Start.

2. Initialize counter to zero and n as input number.

3. Start while loop with condition counter<=5

4. read the number, check the condition >=0

5. if the number is greater than or equal to zero print positive

else

increment counter

6. when counter becomes 5 loop terminates.

7. Stop.

Flow Chart:

Start num=0,counter=0 Stop к — IF counter<=5 ОТКАТА Yes Read num IF num >=0 Yes , Print Positive No counter++

C-Program:

#include<stdio.h>

void main()

{

int num,counter=0;

while(counter<=5)

{

scanf("%d",&num);

if(num>=0)

printf("Positive\n");

else

counter++;

}

}
