Write a C Program to Convert Decimal Number to Binary Number

 #include <stdio.h>
 #include<math.h>
 long decimalToBinary(int decimalnum)
 {



 	
    long binarynum = 0;
    int rem, temp = 1;

    while (decimalnum!=0)
    {
        rem = decimalnum%2;
        decimalnum = decimalnum / 2;
        binarynum = binarynum + rem*temp;
        temp = temp * 10;
    }
    return binarynum;
 }



 int main()
 {
    int decimalnum;
    printf("Enter a Decimal Number: ");
    scanf("%d", &decimalnum);
    printf("Equivalent Binary Number is: %ld", decimalToBinary(decimalnum));
    return 0;
 }
          

Output:

 Enter a Decimal Number: 9
 Equivalent Binary Number is: 1001
