1. EXERCISES for ALGORITHMS WRITING

2. THE PROCEDURE:
Define the problem in terms of Input, Process, Output
Create a solution algorithm using pseudo-code
Problem No.1: Add three numbers
A program is required to read 3 numbers, add them together
and print their total.
Inputs: num_1, num_2, num_3
Process: Addition
Outputs: Display total of three numbers
Algorithm:
- Define num_1, num_2,num_3 and total
- Read num_1
- Read num_2
- Read num_3

3. - Add num_1, num_2 and num_3 into total
- Display total
Problem No.2: Find Average Temperature
A program is required to prompt the terminal operator for the maximum and minimum temperature readings on a particular day, accept those readings as integers, then calculate & display to the screen the simple average temperature, calculated by:
(maximum temperature + minimum temperature) / 2
Inputs: max_temp, min_temp
Process: Add the max_temp & min_temp and then
divide by 2
Outputs: Display avrg_temp

4. Algorithm:
- Initialize max_temp, min_temp, avrg_temp
- Read max_temp
- Read min_temp
- Add max_temp & min_temp and then divide by 2 into
avrg_temp
- Display avrg_temp
Problem No.3: Display Characters
Construct an algorithm that will prompt user to input 3 chars, receive those 3 chars and display them to screen with a message, such as Hello ABC
Inputs: chr_1, chr_2, chr_3
Outputs: Display “HELLO” with chr_1, Chr_2, Chr_3

5. Algorithm:
- Initialize chr_1, chr_2, chr_3
- Get chr_1
- Get chr_2
- Get chr_3
- Display chr_1, chr_2, chr_3 with a Hello message
Problem No.4: Calculations
A program is required to receive two integers from a terminal operator / user, process them and display to the screen their sum, difference, product and quotient
Inputs: num_1, num_2
Process: Addition, Subtraction, Multiplication & Division
Outputs: Display sum, diff, mul and div

6. Algorithm:
- Initialize num_1, num_2, sum, diff, mul, div
- Get num_1
- Get num_2
- Add num_1 & num_2 into sum
- Subtract num_1 from num_2 into diff
- Multiply num_1 with num_2 into mul
- Divide num_1 by num_2 into div
- Display sum, diff, mul and div
