Question

could some one help me out with this code please it says the function name is
nth_digit:
(int, int) -> int

and the description is
The first parameter is an arbitrary integer that you can think of as being base 10. The second parameter is an integer that specifies a digit in the first parameter. This function returns that digit. Digits are counted from right to left, so that 0 represents the 0s digit, 1 represents the 10s digit, 2 represents the 100s digit and so on. So nth_digit(123,0) should return 3, nth_digit(123,1) should return 2, and nth_digit(123,2) should return 1.

Answer 1

You can assume the first number is positive, and the second number refers to a digit that is explicitly written. So you will not need to handle something like nth_digit(123,4).

i do not know how to do this problem please help me outt

Answer 2

In c language try it......
#include<stdio.h>
#include<conio.h>
int nth_digit(long int,int);
void main()
{
long int n;
int p,b;
printf("Enter any number:");
scanf("%ld",&n);
printf("Enter the position of number do you want to know");
scanf("%d",&p);
b=nth_digit(n,p);
printf("the number at this position is %d",b);
getch();
}
int nth_digit(long int x, int y)
{
int a[30],i=0,k;
while(x>9)
{
a[i]=x%10;
x=x/10;
i++;
}
a[i]=x;
k=a[y];
return(k);

Answer 3

}

Answer 4

Answer 15

wait 10 minutes i am giving you source code in python for this program.today this is my first attempt in python language bro.this is so interesting..

Answer 16

like he also gave this for help

def nth_digit():
#You need to change the parameters.
pass

Answer 17

lol i would honestly really apppreciate it thanks a lot

Answer 18

hamza bhai ....first of all, write all the codes which has you tried for this program i will check it..

Answer 23

i need it for introduction computer programmingg course

Answer 24

in which class

Answer 25

you need to be able to pick out a digit from the first number passed in.
can formulate some pseudo code to do this?

Answer 26

csc108 introduction to computer programming

Answer 27

forget python. try and do this mathematically first.

Answer 28

@asnaseer i have do it in c ..and it is running and give correct output but how can i do this in python...

Answer 29

omg its so confusing both mathematically and in python

Answer 30

Taufique - the aim of this site is to teach - not just give entire answers out.

Answer 31

hamza - think about how to pick out a certain digit using maths

Answer 32

so in the number 1234, what can you do to isolate the digit 4?

Answer 33

yes I know it sorry

Answer 34

hamza-- try it your self only i can give you direction..

Answer 35

alright i am trying

Answer 36

step1:take a number and position of digit which you want to know from the keyboard ....
step2:declare a function to do this task.....
step3:logic...it is very important step in any language..
in this step declare an array ..
for example if anyone enter 12345 number then
12345%10=5 and 12345/10=1234
1234%10=4 and 1234/10=123
123%10=3 and 123/10=12
12%10=2 and 12/10=1
if number<9 stop this process and insert all the remainder in the array..like

now if you have entered 2 then output will be 3 from the array...now implements this in python...
