Implémentation d'un programme en langage C pour convertir le décimal en binaire

while(dno != 0){
   rem = dno % 2;
   bno = bno + rem * f;
   f = f * 10;
   dno = dno / 2;
}

#include<stdio.h>
long tobinary(int);
int main(){
   long bno;
   int dno;
   printf(" Enter any decimal number : ");
   scanf("%d",&dno);
   bno = tobinary(dno);
   printf("</p><p> The Binary value is : %ld</p><p></p><p>",bno);
   return 0;
}
long tobinary(int dno){
   long bno=0,rem,f=1;
   while(dno != 0){
      rem = dno % 2;
      bno = bno + rem * f;
      f = f * 10;
      dno = dno / 2;
   }
   return bno;;
}

Enter any decimal number: 12
The Binary value is: 1100

#include <stdio.h>

   int dno;
   printf("Enter a binary number: ");
   scanf("%ld", &bno);
   dno=todecimal(bno);
   printf("The decimal value is:%d</p><p>",dno);
   return 0;
}
int todecimal(long bno){
   int dno = 0, i = 0, rem;
   while (bno != 0) {
      rem = bno % 10;
      bno /= 10;
      dno += rem * pow(2, i);
      ++i;
   }
   return dno;
}

Enter a binary number: 10011
The decimal value is:19
