c-dec2bin-decimal-to-binary: Decimal to Binary Conversion

This C program converts a decimal number entered by the user into its binary equivalent.

How to Use

1. Cloning from GitHub:

   • If you don't have Git installed, visit https://git-scm.com/downloads to download and install it.

   • Open a terminal window and navigate to your desired project directory.

   • Clone this repository using the following command:

     git clone https://github.com/akumathedyn123/c-dec2bin-decimal-to-binary.git

   This will create a new directory named c-dec2bin-decimal-to-binary in your current location.

2. Compiling and Running:

   • Linux/macOS:

     Open a terminal window, navigate to the project directory (c-dec2bin-decimal-to-binary), and compile the code using a C compiler like GCC:

     gcc main.c -o dec2bin

     This creates an executable file named dec2bin (dec2bin.exe). Run the program by typing:

     ./dec2bin

   • Windows:

     • Install a C compiler like MinGW (https://www.mingw-w64.org/).

     • Open a command prompt or terminal window and navigate to the project directory.

     • Compile the code using the following command (adjust the path to your MinGW compiler if necessary):

       mingw32-gcc main.c -o dec2bin.exe

     • Run the program by typing:

       dec2bin.exe

Usage:

The program will prompt you to enter a decimal number. After you enter the number and press Enter, it will display the equivalent binary representation.

Example:

Enter a decimal number: 15
The Binary equivalent: 1111

How the Code Works

• The dec2bin function takes an integer n as input.
• It initializes binary to store the binary equivalent, tracker to keep track of the place value in the binary number, and neg to check if the input is negative.
• If n is negative, it's converted to its positive absolute value using n = -n.
• A while loop iterates as long as n is greater than 0.
  • Inside the loop:
    • The remainder (n % 2) gives the last digit of the binary number. This is multiplied by tracker and added to binary.
    • n is divided by 2 to remove the last digit for the next iteration.
    • tracker is multiplied by 10 to represent the next place value in the binary number.
• If n was originally negative, two's complement is calculated using bitwise inversion (~binary) and adding 1 to get the correct binary representation for negative numbers.
• The main function prompts the user for a decimal number, calls dec2bin to convert it, and prints the result.
