How to Make a Basic C++ Program

Intro: How to Make a Basic C++ Program

Welcome. In this instructable you will learn to make a simple non- graphical c++ program. The program will convert celsius to farenheit.

Step 1: Making It!!!

So lets start making it. These are the codes for making it :


#include
#include

main()

{clrscr();
int c, f;
cout << "Welcome, this is a program to covert celsius to farenheit\n\n\n";
cout << "Enter the degree in celsius: ";
cin >> c;
f = c * 1.8 + 32;
cout << "The degree in farenheit is " << f;
getch();
return 0;
}


Step 2: Video Tutorial

Here is a video of the program:

 

Step 3: How It Works

In thisstep I will tell you how it works.

#include <iostream.h>
#include <conio.h>             -          These lines add the base files i.e. iostream.h and conio.h

{clrscr();      -       The '{' marks the starting of our main code. clrscr() means clear screen which clears anything that was written before.
int c, f;       -         This line declares that 'c' and 'f' are integers.
cout << "Welcome......"\n\n\n;          -      This line prints and when we use " symbol it prints the exect words. \n means next line so the next line after leaving 3 lines.
cout << "enter.....";      -          It does the same as the upper one.
cin >> c;                 -              It takes the input of the value of 'c'.
f = c * 1.8 + 32;           -           This line declares the value of 'f'.
cout << "The........ << f;                    -                This line first prints the sentence then it prints the value of f because we didn't use " symbol.
getch();         -           This line halts the program. Without this line the program will come and go in 1 second.
return 0;        -        This line marks the completion of the program
}         -           This bracket is completing the program's code






Step 4: How and Why I Made It

One day I was doing my homework. There were a lot of questions that included converting celsius to farenheit so I thought why not make a program that will do my work. So I got on my computer and started making it.I will be honest, I took some help from my brother.After making it I learnt a lot of things about c++. The next time I make it I will make a graphical one.

    Why not explain the code a little bit more. And I think you got this code out of Beginning Programming with C++ for Dummies

    Had to find out how to do it in linux.

    #include
    #include
    using namespace std;

    main()
    {

    std::system ( "clear" );

    int c, f;
    cout << "Welcome, this is a program to covert celsius to farenheit\n\n\n";
    cout << "Enter the degree in celsius: ";
    cin >> c;
    f = c * 1.8 + 32;
    cout << "The degree in farenheit is " << f << "\n";
    cin.get();
    return 0;
    }

    convention states your use of {} is either right after the function call or one line after. i.e.
    main(){
    }
    or
    main()
    {
    }

    this allows better reading of the code.
    if you use cout as you have you should keep each part seperate from other parts. weird that didnt sound right but i.e
    cout << "Welcome, this is a program to convert Celsius to Farenheit."
    cout << "\n"
    cout << "Enter the degree in Celsius:"
    cin >> c

    again this is to keep the code clean and readable for the next coder. not that there would be a next coder however if you do it all the time you make it a habbit and it helps later on in a career.

    hope i helped
