Sequential Programming

By: Muhammad Zidny Nafan

Introduction to Sequential Programming Executing program one by one instruction One isntruction exact one execute. No

instruction will be repeated The order of instruction will be executed by

the order in text (source code) The latest instruction is the latest algorithm

Example 1 Print Hello World in screen

Example 2 Count square’s area

Example 3 Problem: A salesman will receive commision

from sale as big as 5% for each sale. Write the program to count salesman’s commision

The algorithm is first program will asked user to input salesman’s name, and total sale. Then program will count commision. Then print name and commision in screen.

Example 3 Solving Problem: that program need 3

variablesvariable Data type

name string

sale long int

commision double

Example 3 Code:

Example 4 Convert time to second Problem: A runner take on run time in hour,

minute, and second. Write a program to convert run time become second. (example: run time= 1hour, 1minutes, 3second = 3663seconds)

Solving: formula: (hours*3600) + (minutes *60)+seconds

Example 4 Code:

Exercise 1Write program with these processes: Show “hello world” in screen Ask user to input his name And then print this message in screen:

“Nice to meet you, <name>.”

Exercise 2Write a program that asks the user to

type the price without tax of one kilogram of tomatoes, the number of kilograms you want to buy, and the tax in percent units. The program must write the total price including taxes.

Exercise 3 Write a program that asks the user to type 5

integers and writes the average of the 5 integers. (but use only 2 variables).

Exercise 4Write the program to help swalayan caseer for splitting return money by 50.000, 20.000, 10.000, 5.000, 2000, 1000, 500,and 100. Contoh:Return money : Rp. 88800Splitting

1 pieces 50.0001 pieces 20.0001 pieces 10.0001 pieces   5.0001 pieces    20001 pieces    10001 pieces      5003 pieces      100
