C Program to Convert Decimal to Binary System

Write a C Program to Convert Decimal to Binary System using Recursion. Here’s simple Program to Convert Decimal to Binary System using Recursion in C Programming Language.

Recursion : :

• Recursion is the process of repeating items in a self-similar way. In programming languages, if a program allows you to call a function inside the same function, then it is called a recursive call of the function.
• The C programming language supports recursion, i.e., a function to call itself. But while using recursion, programmers need to be careful to define an exit condition from the function, otherwise it will go into an infinite loop.
• Recursive functions are very useful to solve many mathematical problems, such as calculating the factorial of a number, generating Fibonacci series, etc.

Problem : :

The following C program using recursion finds a binary equivalent of a decimal number entered by the user. The user has to enter a decimal which has a base 10 and this program evaluates the binary equivalent of that decimal number with base 2.

Below is the source code for C Program to Convert Decimal to Binary System using Recursion which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

```/* C Program to Convert Decimal to Binary System using Recursion */

#include <stdio.h>

int convert(int);

int main()
{
int dec, bin;

printf("Enter a decimal number: ");
scanf("%d", &dec);
bin = convert(dec);
printf("The binary equivalent of %d is %d.\n", dec, bin);

return 0;
}

int convert(int dec)
{
if (dec == 0)
{
return 0;
}
else
{
return (dec % 2 + 10 * convert(dec / 2));
}
}```

Output :

```***************** OUTPUT *******************

Enter a decimal number: 10

The binary equivalent of 10 is 1010.```
