Converter a Number from Decimal to Binary
In the following example, we will convert a Decimal Number (500) to Binary Number (111110100).
Tips: It is recommended to use our online Decimal to Binary calculator for better understanding.
Example
C Compiler
#include <stdio.h>
int main()
{
int num = 500;
int arr[50];
int i = -1, j;
while(num != 0)
{
i++;
arr[i] = num % 2;
num = num / 2;
}
printf("Binary number of 500 (decimal) is ");
// reverse the array and display
for(j=i; j>=0; j--)
printf("%d", arr[j]);
return 0;
}
Output
Binary number of 500 (decimal) is 111110100
Converter any Given Decimal Number to Binary Number
In the following example, we will convert any given decimal number to a binary number.
Example
C Compiler
#include <stdio.h>
int main()
{
int num, copyNum, arr[50], j;
int i = -1;
printf("Enter a Decimal Number: ");
scanf("%d", &num);
copyNum = num;
while(copyNum != 0)
{
i++;
arr[i] = copyNum % 2;
copyNum = copyNum / 2;
}
printf("Binary number of %d (decimal) is ", num);
// reverse the array and display
for(j=i; j>=0; j--)
printf("%d", arr[j]);
return 0;
}
Output
Enter a Decimal Number: 10
Binary number of 10 (decimal) is 1010
