void conv(int n, int b);

int n;

clrscr();

printf("\n enteu any Natural  number :\n");

scanf("%d",&n);

void conv(int n, int b)

{

int rem[15];

int i=0;

while(n>0)

{

rem[i]=n%b;

n=n/b;

i++;

}

if(b==2)

printf("\n Binary Conversion  :\n");

if(b==8)

printf("\n Octal Conversion  :\n");

if(b==16)

printf("\n Hexadecimal Conversion  :\n");

for(i=i-1;i>=0;i--)
