EXERCISES for ALGORITHMS WRITING

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

- 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

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

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

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
