Hello again Codescharter, it took so long since my last devlog. As you may have read on the title this mock up project is about creating an Ordering System in C++. We may go to any fast-food stores, or any convenient store as a buyer. You are surely aware seeing a list of your orders in the screen, right? This system we are about to make is a simple as other programming system here on my blog. But don't you ever consider an ordering system as to easy coz' it may become a super system. What is a super system? Software system is composed not just one, but multiple systems.
What is the important of learning of ordering system?
Surely you must be aware of rapid growth of technology in our society. Where people are now buying their stuff on the internet, or may visit to buy books in your favorite bookstore. To long before computer came out this system actually exist, or you try to pay a visit to the local market area that are nearest from your location. You will probably hear people who are buying their stuff right from their hands.
Now lets code Ordering System in Step by Step
1. First set up a the main function
1 2 3 4 5 6 7 | #include<iostream> #include<conio.h> using namespace std; int main(){ return 0; } |
As you may be wonder for what can #include<iostream> do to your program well having it declared making you to be able to use or call all c++ functionality and syntaxes. On the lined to is a header for extra functionality that you’d like to have in your program. Remember that iostream can only be used for c++ program only, while conio.h can be used for both c++ and c. on the lined three you see using namespace std. for c++ program very useful to get rid off std:: commands. The main function where you will input your program.
2. Declaring variables
5 6 | int price, quant, set1 = 95, set2 = 100, set3 = 125, set4 = 115, payment, total = 0; char choice, gmenu; |
the int stands for integer where you are being able to store numerical numbers for specifically a decimal numbers or whole numbers, while char stands for character to stores a single letter value or alphabet. You see I declare many in integers and being separated by comma’s. do you even recognize those integers like set1 with an equal it’s about to replace its default value from one to 95.
