THE PROCEDURE:a. Define the problem in terms of Input, Process, Outputb. Create a solution algorithm using pseudo-code

Problem No.1: Add three numbersA program is required to read 3 numbers, add them togetherand print their total.

Inputs: num_1, num_2, num_3Process: 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 TemperatureA 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 CharactersConstruct 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: CalculationsA 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
