#include<stdio.h>

int main(){
  
  
   int integer;
   // array to store binary number
int bin[32];
// array to store hexadecimal characters
int hex[32];
  
printf("Enter an integer: ");scanf("%d",&integer);
int i = 0;
int n=integer;
while (n > 0) {
  
// storing remainder in binary array
bin[i] = n % 2;
n = n / 2;
i++;
}
// printing binary array in reverse order
for (int j = i - 1; j >= 0; j--)
printf("%d",bin[j]);
n=integer;
i=0;int remainder;
while(n>0){
// storing remainder in hex array
hex[i] = n % 16;
n = n / 16;
i++;
   }
   printf("\n\n");
   // printing hex array in reverse order
for (int j = i - 1; j >= 0; j--)
if(0<=hex[j] && hex[j<10]<10)printf("%d",hex[j]);
else if(hex[j]==10)printf("A");
else if(hex[j]==11)printf("B");
else if(hex[j]==12)printf("C");
else if(hex[j]==13)printf("D");
else if(hex[j]==14)printf("E");
else printf("F");
