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.

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;
}

Here is a video of the program:

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

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.
