Binary System: A number system with base 2 i.e, only binary numbers 0 and 1 are used to represent a binary number system.
C program to convert a decimal number into a binary number
#include <stdio.h> #include<stdlib.h> void main() { int arr[20]; int num,i; printf("Enter the number: "); scanf("%d",&num); int n= num; for(i=0;num>0;i++) { arr[i] = num%2; num = num/2; } printf("Binary Value of %d is: ",n); for(i=i-1; i>=0; i--) printf("%d", arr[i]); } |
Output
Enter the number: 15 Binary value of 15 is: 1111 |
