Question

write a program in recursion to convert decimal to binary​

Answer 1

Answer:

#include <stdio.h>

int convert(int);

int main(){

   int dec, bin;

   printf("Enter a decimal number: ");

   scanf("%d", &dec);

   bin = convert(dec);

   printf("The binary equivalent of %d is %d.\n", dec, bin);

   return 0;

}

int convert(int dec){

   if (dec == 0){

       return 0;

   }else{

       return (dec % 2 + 10 * convert(dec / 2));

   }

}

Output:

Enter a decimal number: 10

The binary equivalent of 10 is 1010.
