Non-Iterative Algorithm(Simple Input-Process_Output

In non-iterative algorithm we usually accept/input data to find/calculate some values either through some formula or from simple calculation. Once calculation is done we release the results. In some questions your calculation might be conditional, some time your output would be depending on some criteria but in any case there wont be any loop involved.

Write an algorithm in the form of a flowchart which takes temperatures input in Fahrenheit. Convert the temperature in Celsius with the help of following formula:Temp (in Celsius)=(Temp (in Fahrenheit) - 32)/1.8

Practice question:Question 01:Customers can withdraw cash from an Automatic Teller Machine (ATM). withdrawal is refused if amount entered > current balance withdrawal is refused if amount entered > daily limit if current balance < $100, then a charge of 2% is made if current balance $100, no charge is madeWrite an algorithm which inputs a request for a sum of money, decides if a withdrawal can be made and calculates any charges. Appropriate output messages should be included.

Practice Questions:Question 01:A company has 5000 CDs, DVDs, videos and books in stock. Each item has a unique 5-digit code with the first digit identifying the type of item, i.e.1 = CD2 = DVD3 = video4 = bookFor example, for the code 15642 the 1 identifies that it is a CD, and for the code 30055 the 3 identifies that it is a video.

Write an algorithm, using pseudocode or otherwise, that Inputs the codes for all 5000 items Validates the input code Calculates how many CDs, DVDs, videos and books are in stock Outputs the four totals.

Question 02:5000 numbers are being input which should have either 1 digit (e.g. 5), 2 digits (e.g. 36), 3 digits (e.g. 149) or 4 digits (e.g. 8567).Write an algorithm, using pseudocode or flowchart only, which inputs 5000 numbers outputs how many numbers had 1 digit, 2 digits, 3 digits and 4 digits outputs the % of numbers input which were outside the range

Question 03:A company is carrying out a survey by observing traffic at a road junction. Each time a car, bus, lorry or other vehicle passed by the road junction it was noted down. 10 000 vehicles were counted during the survey. Write an algorithm, using pseudocode, which: inputs all 10000 responses outputs the number of cars, buses and lorries that passed by the junction during the survey outputs the number of vehicles that werent cars, buses or lorries during the survey

Totaling

Totaling is usually done when you have to calculate average. In totaling we add the value entered by user or derived from any calculation. Calculation of average and result of total and average will be placed outside the loop. Never calculate average or show result of total or average inside the loop.

Practice Questions:Question 01:A school is doing a check on the heights and weights of all its students. The school has 1000 students.Write an algorithm, using pseudocode or a flowchart, which inputs the height and weight of all 1000 students outputs the average (mean) height and weight includes any necessary error traps for the input of height and weight

Question 02:Write an algorithm, using pseudocode, which inputs rainfall (in cm) for 500 days and outputs the average rainfall.Question 03:Fuel economy for a car is found using the formula:

Write an algorithm, using pseudocode or otherwise, which inputs the Distance Travelled (km) and the Fuel Used (litres) for 1000 cars. The Fuel Economy for each car is then calculated and the following outputs produced: Fuel Economy for each car average (mean) Fuel Economy for all of the cars input

Extreme Values

On many occasion you will be asked to find highest or lowest values or both. We call it finding extreme values i.e. maximum/minimum, highest/lowest, fastest/slowest etc. For example Write an algorithm in the form of a flowchart which takes temperatures input over a 100 day period (once per day) and outputs the highest and lowest temperature recorded in these 100days.
