Conversion program from decimal to binary

Conversion program from decimal to binary

Question:

Write a program to convert the given number from decimal to binary.

Logic:

  • The number for conversion is getting from the user.
  • Modulus value of the number gives binary value.
  • Then divide the number by 2.
  • And then print the binary value.

Algorithm:

  1. Get the input number from the user.
  2. Take modulus of the number and stores into the array.
  3. Divide the number by two.
  4. Repeat step 2 and 3 until number becomes zero.
  5. Then print the binary number.

Program:

#include<stdio.h>
void main()
{
	int a[20],i=0,n,c;
	clrscr();
	printf("enter the number:");
	scanf("%d",&n);
	while(n>0)
	{
		a[i]=n%2;     //stores the remainder values as o's and 1's
		n=n/2;        //divide the number into half
		i++;          //increments the index value
	}c=i;                 //length of the binary number
	for(i=c-1;i>=0;i--)   //prints the binary numbers
	{
		printf("%d",a[i]);
	}
	getch();
}
