How can I make fibonacci output larger result?

I can't the right result of Fibonacci(10) or larger number .Help!


#include<stdio.h>

long fibonacci( long n);

int main()
{
long result;
long number;

printf("Enter an integer : ");
scanf("%1d",&number);

result =fibonacci( number );

printf("Fibonacci( %1d ) = %1d\n",number,result);

return 0;
}

long fibonacci( long n )
{
if( n == 0 || n == 1){
return n;
}
else{
return fibonacci( n-1)+fibonacci(n-2);
}
}
