I do plastic surgery. You can also use other data types. Pay great attention to the range of data types here. The plastic I use can be up to 39 th.

# include & ltstdio.h & gt

void main()

{

int n，I；

int a[99]={ 1， 1，}；

int count = 1；

Printf ("Please enter the nth digit:");

scanf("%d "，& ampn)；

for(I = 2； I & ltn；; i++)

a[I]= a[I- 1]+a[I-2]；

Printf ("bit %d is", n);

printf("%d\n "，a[n- 1])；

And (0! =a[n- 1]/ 10)

{

a[n- 1]= a[n- 1]/ 10；

count++；

}

Printf ("Number of digits in %d is:", n);

printf("%d\n "，count)；

}

Of course, here I take A0 and A 1 as 1 and 1, and you can also take something else.
